Things You Should Know About Cheap Laptop Batteries

Laptop has become very important in our lives, so that the power source also very important for efficiency and survival of our laptops. If the laptop cannot be used for more than two hours the user will get stuck with a device created for speed and mobility but shut down very quickly because the electricity supply is inefficient.

There are many types of batteries such as nickel hydride, lithium ion batteries and nickel-cadmium batteries. Batteries price depends on the materials used to manufacture them. Among these three batteries, nickel cadmium batteries are the cheapest. The price of nickel cadmium batteries can range from $ 50 to $ 100.

Nickel hydride battery is a little expensive compared to the cadmium batteries. The price of nickel hydride batteries can range from $ 80 to $ 150. A lithium polymer battery is more expensive than the two types of batteries mentioned above.

Another discovery is revolutionizing the laptop battery is a new external battery  that offers run-time of about seven hours in about half the price, but also depends on the programs used on a laptop. Many vendors on the internet offer cheap laptop batteries when purchased in large quantities.

Some companies offer a discount on the battery if the same company that produces laptops. Alkaline batteries are the cheapest among batteries, but bear the highest cost per cycle. Other cheap laptop batteries include lithium ion batteries and lithium ion polymer batteries. Cheap laptop batteries are also available in the Chinese market and can be sent to the United States with reservations over the Internet.

Life of a battery can be increased about fifty percent, so lowering the same price. Many preventive measures can be taken in order to increase the battery life like – fully discharging and charging the battery at least once a month back, the battery remains cold and dry, and make sure that the battery is not overcharged.

Things You Should Know About Laptop Battery Chargers

There are two types of laptop batteries consist of nickel metal hydride and nickel cadmium. We recommend that you fill in a new battery in cycles of fourteen to sixteen hours. Your battery should be allowed to cool down before charging as overcharging will shorten their lives.

The price laptop battery chargers range from $ 200 to $ 300 and have one year warranty period. Ready access to important chargers for nickel cadmium may suffer from a ‘flawed memories”.

The owner of the laptop may face this problem if the battery is not fully discharged before charging. A nickel-cadmium battery must be charged only once been completely exhausted. There are two ways to recharge laptop batteries.

First, every time the PC using the AC power, a small electric current to the battery ran called trickle charge. This fee will automatically recharge the laptop battery after it was decided. The second is with external laptop battery chargers. Battery charger plugged into, then the charger is plugged into a standard electrical outlet.

Some chargers are available in the market offering to charge the battery in seven hours, but this can permanently damage the battery. Nickel-cadmium batteries tend to break away, which means they can lose power when they are not being used.

Laptop battery chargers solve this problem by providing a small charge batteries that store the battery fully charged. Nickel-cadmium batteries work more efficiently when they are fully discharged and then recharged.

If the battery is used in a fashion that more little by little and then, sometimes fully discharging the battery before charging to the same increase productivity. Some laptop battery chargers do this automatically, but leave your laptop during the night and charging the battery in the morning also can refresh the battery efficiently.

A few things you should know about your Laptop Battery

We can see laptops every where, they’re becoming more and more popular as they are light, portable and personal to each of us. It is like they are nondetachable part of our daily life.

But behind every Laptop is lying the power source which runs everything from CPU to DVD Rom, laptop battery at the edge of technology which is getting thinner, more powerful and easier to handle everyday thanks to improvements and researches have been made. But do we know enough about them? How to charge-discharge them, how long they will run our laptop and when is the time to replace them…

Hope this following article will help you get a better understanding of a laptop battery and it’s functionality:

(1.) Does using the wireless network card drain a laptop battery?

Yes, wireless network cards do reduce the battery run time. It is difficult to quantify the adverse effect a wireless card has on battery run time because it varies depending on laptop model and wireless card. The operating system and the software installed with the card may have utilities for conserving battery life.

(2.) Does disconnecting USB devices from my laptop, help conserve battery life?

Yes, disconnecting USB devices helps conserve battery life. It has also been widely reported that a flaw in Windows XP affects certain Intel based laptops to drain the battery at a faster rate than normal when a USB device is connected.

(3.) How long should my new rechargeable battery last?

The life of a battery under normal use is around 500 to 900 charge-discharge cycles times. This is between one and a half to three years of battery life for the average user. As the rechargeable battery begins to fail the running time of the battery will begin to drain. When a battery can supply only around 30 minutes of charge, it is time for a new replacement.

(4.)What is the run time of a battery? How long will my laptop stay ‘powered’ with the battery?

Run time varies between each laptop. This makes it difficult to tell exactly how long a battery is will last. There are several other factors that affect a batteries run time:

(a.)The chemistry and capacity of the battery (Li-ion, Ni-Mh, Ni-Cd)

(b.)How old your laptop battery is.

(c.)The number of times a file is saved or retrieved from the hard drive or DVD Rom drive.

(d.)The type of software being run, i.e. some applications such as games, graphical software or wireless networking will dramatically reduce run time.

But for overall, a realistic predict of run-time for our laptops is between 1.5-2 hours (4400mah),3-4 hours(7200amh),5-6 hours(10400mah)…etc

What You Should Know about Lithium Ion Laptop Battery

The greatest advantage of owning a laptop is its unmatched portability. The battery power is a decisive factor to determine how long you could use your laptop in the place where electricity is unavailable. The most common-used laptop batteries today are Lithium Ion batteries.

Traditional rechargeable batteries might have “memory effect” that does not apply to Lithium Ion. The effect is also used to explain once there is any battery doesn’t work for us at its full capacity. In order to overcome this, people charge this laptop battery in certain ways to avoid or fix. Lithium Ion batteries’ poor performance is usually caused by mishandling or age.

Quite a few of us like to fully discharge a laptop battery before we recharge it. This is wrong. Lithium Ion laptop batteries have limited amount of charge cycles – a fully discharge will shorten its serving life span.

How to make your laptop battery pack have longer life span?

The charge cycles of Lithium Ion batteries are from 300 to 600, which could be used from 2 to 4 years. For taking advantage of your laptop battery optimally, the following things you should notice:

* If you don’t need the laptop to finish a task, don’t forget to enable the power saving feature while you use your laptop on battery power.

* Calibrate your battery with a full discharge every 30 charges for keeping its fuel gauge’s accuracy. Before recharging, set your setting to the automatic cut-off point.

* Disconnect the battery when you use AC power. If the two used at the same time, the internal temperature of the battery rises, thus the aging process of your battery accelerate.

* For battery not use for a long time, make sure that it has about 40% charge level and store in a cool dry place. Lower temperature slows down aging process of laptop battery.

* If you like to use battery to run your laptop, charge it as often as possible.

* If the outside temperature is high, don’t leave your laptop or battery in your car. Higher temperature shortens the life of your battery.

Things You May Not Know About Laptop Battery

As usual, most manufacturers will tell you that a laptop battery can run up to 2 hours, but actually not. After a certain time, the laptop battery will be running shorter and shorter so that we need more often to charge it. Laptop battery degradation will happen overtime. However, we can try to minimize the degradation by knowing some laptop battery information.

We all know that any new laptop battery usually comes empty with the laptop. Thus, it is suggested that you charge the battery at least 4 hours non-stop on the first charging. This can help to prolong the laptop battery’s lifespan. Also, it is not suggested that you use the laptop battery at all during the first charging.

Due to that laptop battery types are different, it is important to know how you should charge the battery. Nickel Cadmium laptop battery is an older type. For this kind of battery, it’s suggested that you use it until empty, and then charge it to full. Lithium based battery is another type of battery. For this kind of battery, it’s suggested that you use the battery until 10%-20% before you charge it to full.

After you have got to know how to charge the laptop battery, it is time to know about effective usage of laptop battery. On Windows base, it’s suggested that you use the Power Schemes for Laptop to control how the laptop behaves after a period of inactivity. This can greatly reduce the drainage on the laptop battery. Also lowering the brightness of laptop LCD monitor is a good way to reduce the laptop battery usage.

After knowing these laptop battery information, you should be able to know how to prolong the laptop battery lifespan and also maximize your runtime when running on battery.

About Laptop batteries… 

Keeping your laptop running for longer without recharging…
The beauty of notebook PCs is the portability, making them an essential device with an obivous advantage of mobility over desktop computers. Of course, after several hours, you will need to recharge your laptop’s battery(for example,dell inspiron 2650 battery), plugging an AC charger from the mains into your laptop, which means, for a short period of time, it’s fixed to one place, making it effectively a desktop PC for a short while. Annoying, but with the incredibly increased run times from new laptop computers on the market, the need for recharging is less frequent, as battery run-times have significantly increased over the past few years. It’s not uncommon to have a laptop that can run for a working day without recharge, making it ideal for those on the move.

Of course, if you’re demanding a lot of performance from your machine, the battery will drain faster than normal. Your system might be running unnecessary programs right now, which creates a burden on the battery run time. We have a few tips for you to get the absolute potential from your laptop and its battery. These tips apply to old as well as new laptop computers, for the now ubiquitious Lithium Ion (Li-Ion) batteries, the Nickel Metal Hydride (Ni-MH) batteries and the virtually obsolete Nickel Cadmium (Ni-Cd) batteries.

1  Essential treatment of a new battery

Whether you have a new battery, or a totally brand new laptop system, the most important thing to do before normal usage is to fully charge the dell inspiron 2650 laptop battery to 100%, then deliberately discharge it completely. Then, charge it up again, and use your laptop normally. Why do this? Well, this method allows your battery to ‘learn’ how much electrical charge it can hold. Without this important treatment, you won’t be getting the potential out of your battery’s life span. Also, ensure that when you charge your battery, it reaches 100 percent.

 2  Turn down your screen brightness!

The LCD display is quite a big drain on your battery power. Do you really need the brightness on the highest setting? Adjust your display so that the screen is not fully lit, but comfortable enough for your viewing. This will help increase your battery run time.

 3  Use power wisely

Unused devices are also a drain on your system’s power. Remove USB devices and other connected units when they’re not needed. Try to only use your CD/DVD drive when necessary. If you need to repeatedly access files/music from a disc, it helps to copy the material to your hard disk – the spinning of a CD/DVD to read files is a huge factor in battery drainage, whereas hard disk access is a significantly lighter burden. If you’re not using your laptop, put it into sleep mode, which keeps enough power running to maintain minimal function, so you can resume full power when you’re ready to return to your work or play. Also, close down programs you’re not using. If you don’t have a net connection, you won’t be needing a web browser or an Instant Messenger running, for example.

 4  Streamline your system’s hard drive

If you’ve been using your computer quite a lot, it helps to defragment your hard drive. This cuts out a lot of work your computer must do when accessing files. You can do this in Windows XP by clicking on the START button, All Programs, Accessories, System Tools and selecting Disk Defragmenter. It’s simple to use, and should be performed regularly to get the most out of your system. Doing this will ease stain on your hard drive, and thus will make the battery run time last longer.

 5  Remove start-up items

When you switch on and run Windows, start-up items load into memory, adding to the load on your CPU. It’s possible that you may never use any of these programs in your session, but with them hanging around ready to be used, your battery will be drained further. You can review and remove selected programs from the start-up process by clicking the START button, selecting RUN… and type MSCONFIG into the prompt.

 6  The heat is on…

High temperatures are not good for laptop batteries. They work at their best in cold conditions, although they are optimised for great usage at room temperature, so you don’t have to worry about taking your laptop into an igloo to have it running! Where possible, keep your laptop battery away from excessive heat and/or hot weather – which is also vital for the safety of batteries. Having your battery relatively cool will increase its total lifespan. It can help to remove the battery and utilise AC power from the mains when possible, to keep the battery lifespan safe.

 7  Power up frequently

Lithium Ion (Li-Ion) batteries should be charged as soon as possible, and often. (The exception to this rule if if you’re not using them for a longer time, in which case you should bring them to a charged level of 40%.) Get your battery charged up before it hits 0%, this will prolong the battery lifespan and avoid major problems.

 8  Storing spare or rarely-used batteries

We’re not kidding, the best place for a rarely used Lithium Ion (Li-Ion) laptop battery is in your refridgerator – the benefits for the battery lifespan are at the best! At 0°C, the battery loses less charge than at higher or lower temperatures. Before doing this, we recommend the charge to drop to 40%. We also highly recommend that when taking a dell inspiron 2650 battery out of such a cold condition, that you let it remain in room temperature for at least 24 hours before using it in any laptop.

See About Dell Alienware M15X Laptop Battery

Stay unplugged longer with the new Dell Alienware M15X 7800mAh 5200mAh Li-ion dell Inspiron Battery. This 10.8V Rechargeable Li-ion battery can replace the original system battery or be used as a spare. Dell computer batteries  life (and recharge times) will vary based on many factors including screen brightness, applications, features, power management, battery conditioning and other customer preferences.

Alienware announced a compact high performance notebook a long time ago. But although it was already available in the USA for quite a while, it is just now finally coming to Europe. The Area-51 m15x notebook makes Alienware the first producer that offers a 15? gaming notebook with a 8800 GTX graphics card and Intel Core 2 extreme processor. This is also the current maximum of what’s possible in the compact multimedia class. Compared with other Alienware models we tested so far, the Area-51 m15x looks very simple and discreet (fujitsu battery), at least as long as the various LED lights aren’t activated. The display lid and the base unit are kept in a silver-grey plastic frame. We especially liked the seamless workmanship of this part, which creates a compact impression of the notebook.

The geometrical and simple shape perfectly fits the colour scheme. The most outstanding details are firstly the two openings on the left and right of the keyboard, which contain the loud speakers, and secondly the central display hinge. But the Area-51 m15x becomes the center of attention only after turning on the LED illumination. The LEDs are very effective due to the unobtrusive case design, (Cheap FPCBP216 10.8V,3 cell Laptop Batteries,battery for FUJITSU FPCBP216) especially if other light sources are dimmed.

One can tweak the illumination of the Area-51 m15x with the Alien FX Lightning software in the command center. Various different colours or separate areas can be chosen for the light effects. The laptop distinguishes different areas of illumination, like the light pipe around the display in the shape of a small gap that emits light, the illumination of the hot keys, as well as the touch pad and keyboard. Our test sample had a keyboard without illumination however.

Another interesting gadget to personalise the m15x is the aluminum plate on the bottom of the notebook, on which up to 23 characters chosen by the soon to be owner (FUJITSU LifeBook M2010 laptop batteries), are engraved by laser. The text is translated into alien characters and also added to a foil which is put on the touch pad.

Ah yes, don’t forget the well known alien face on the display lid, which is illuminated as well. It starts to pulsate if the notebook is put into standby mode, which is also called “breathing” by Apple. The Alienware m15x unfortunately fails to do this smoothly, so that it looks more like it is clearing it’s throat.

We also had to clear our throat on closer inspection of the case, which makes a compact and robust impression at first due to the design, but clearly disappoints in the actual test (Cheap F310J 11.1V,9 cell Laptop Batteries,battery for DELL F310J). Holding the notebook, lifting it, or applying a bit of pressure, always results in creaky noises, which seem to be the norm with the m15x. Especially bad in this regard are the display and display hinges.

Although the display is with 12 millimeter not exactly slim, it seems to be very susceptible to any kind of pressure or twisting. Just opening and closing the display is apparently already too much for the notebook and results in loud creaking and squeaking. Furthermore, deformations and even colour changes on the display are noticeable. (Cheap a32-f82 11.1V,11.25V,6 cell Laptop Batteries, battery for ASUS a32-f82 ,brand new, 1 year warranty! Ship to most countries)

The hinge itself failed to make a good impression as well. Even though the resistance while adjusting the display is acceptable, the noise it creates and the wobbling of the display after it is put into the desired position is clearly not. Considering it is a compact notebook, which can be carried around, those problems are rather serious.

Especially the creaking noises while working with the notebook overshadow the impression of the m15x. The only average haptics of the plastic parts also fail to change this fact. The low quality is particularly hard to understand if one considers the current price of the Alienware Area-51m15x in our configuration of 2.799.- Euro. ( Replacement battery for ASUS A32-U6, 11.1 voltage, 4400 mAh, 6 cells, Li-ion Laptop Batteries)

The front and the back side of the notebook stay clear of connections. On the front right side of the notebook is a card reader ( 7in1 ) followed by an ExpressCard slot (54mm). Both slots are closed by well shaped flaps. Rubberplugs or plastic dummies are thus unnecessary.

Further back is a HDMI port, which allows a full digital transfer of image and video data. After that comes an USB 2.0 port and a Firewire 1394b (9-Pin) interface, which is a bit unusual for notebooks. Completely at the back is a Kensington lock.

The left side of the m15x is occupied by the power supply, LAN port, two USB 2.0 ports and audio connections (microphone, earphones). All those ports were located at the back half of the left side, which concentrates various cables and prevents annoying cable tangle. The Area-51 m15x has thus not only an extensive enough interface equipment, but also very good alignment of the available ports.

The DVD multi drive is located on the left side on the front. The SmartBay slot could also be equipped with another optical drive, like for example a Blu-Ray drive . Another possibility would be to put an additional hard disk or SQU-724 battery into the SmartBay slot of the m15x.

As opposed to other drives, the Optiarc AD-5540AD doesen’t have a reject button on the drive itself. Instead, it can be opened with the key combination FN+F8.

The m15x has also various integrated communication modules. The gaming notebook offers a Gigabit Ethernet module made by Broadcom for fast transfers over local networks, as well as a wireless LAN card by Intel, standard4965AGN. A Bluetooth 2.0 module provides wireless communication with various extra devices.

Alienware offers only a Kensington lock regarding security, but at least this allows to fix the notebook to a table or other heavy items on LAN parties, to prevent thieves from stealing the notebook.

Included in the shipment of our Alienware m15x test sample was a small leathercase containing the rather short user manual, a thin protection cover, recovery and driver CD ( Cheap UM09A75 11.1V,6 cell 9 cell Laptop Batteries,battery for ACER UM09A75 ), as well as Nero 7 Essentials. Further included was a mouse pad in Alienware design made by Func, which turned out to be very suitable for gaming in our tests ( in combination with a Logitech MX510 mouse ).

The Alienware Area-51 m15x offers a standard keyboard without additional number pad, which is not surprising for a 15.4 inch notebook. The lack of layout experiments, 18×18mm standard keys and the generous enter and space keys, make typing intuitive and adjustments unnecessary.

Typing on the keyboard, which offered a soft stroke and good resistance, was very pleasant as a result. Another positive feature is the quiet typing. The keyboard was also robust, even punctual pressure didn’t cause much deformation of the keyboard unit, which is especially handy when playing fast games that often lead to strong pressure on single keys in the heat of the moment. ( Replacement battery for ACER UM09A31, 11.10 voltage, 7200 mAh, 9 cells, Li-ion Laptop Batteries )

The individual keys seem a bit overloaded, because of the coloured border every key has, which emit light on models with integrated keyboard illumination (38.- Euro extra).

The touch pad is optically very well integrated into the look of the Alienware m15x. It is evenly built into the surrounding case and offers a single continuous touch pad button. The main weakness of the pad is the smooth surface. Alienware included two stickers with rough surface with the notebook that can be put on the touch pad, in order to improve handling. Most users will probably prefer the rough surface, which leads to the question why the pad wasn’t equipped with that surface from the beginning. Compared with the original surface, handling was clearly better after putting the sticker on the touch pad.

The single touch pad key was apparently also produced to please the eye, and not to be user friendly. The continuous button has a very large dead area in the middle (about a third of the total width!), and can only be pressed properly on the left and right edges (Cheap AL31-1005 10.8V,11.25V,6 cell Laptop Batteries,battery for ASUS AL31-1005). We thus highly recommend to use an external mouse, which should be the not a question for a real gamer anyway.

A touch sensitive panel above the keyboard of the m15x provides additional control of the notebook. The term “touch sensitive” is in our opinion not very accurate however, because the symbols require the finger to rest on them for a rather long time to actually react.
Especially annoying in this regard is the adjustment of the volume. A lot of patience is required to get the desired volume.

Alienware currently offers two different displays for the 15.4 inch models. They differ in supported resolution and type of display surface. The choice is between a 1440×900 pixel WXGA+ display with ClearView technology (glossy surface) and a 1920×1200 pixel WUXGA display with matte surface and HD compatible resolution. (ASUS Eee PC 1101HA laptop batteries)

Our test sample was equipped with the high resolution WUXGA display (LPL1801) and was instantly loved because of it’s non reflecting surface. This is unfortunately rare, since multimedia notebooks hardly ever offer matte surfaces. It is thus impressive that Alienware went against the common trend, and offers their high end display with an eye friendly surface.

Fears that the matte display might not be able to compete with glossy displays regarding brightness, colours or contrast, quickly disappeared after a couple of tests. The WUXGA display achieved a very good maximum brightness of 191.3cd/m2 in the central display area. The illumination of the panel is with 87.6% significantly above average.

The measured minimum brightness (black value) of the display was 0.37cd/m2. This, together with the maximum brightness of 191.3cd/m2, resulted in a maximum possible contrast of good 517:1 . Subjectively, the display is always sharp and with good contrast. (Cheap A32-F80 11.1V,6 cell Laptop Batteries,battery for ASUS A32-F80 ,brand new, 1 year warranty! Ship to most countries)

Rather untypical for a gaming notebook, but possible nonetheless, is the outdoor use of the Alienware Area-51 m15x . The dim display surface and the high brightness of the display allow outdoor usage with proper image quality.

The dim WUXGA display offers enough viewing angle stability in vertical and horizontal direction for a sufficiently large working area. The image does hardly change even if the horizontal viewing angle is very flat. Deviations from the optimal viewing angle in vertical direction have a bigger effect however, and overshadowing of the display happens quickly if the viewing angle gets flatter. But this shouldn’t be much of a problem in stationary use. (Cheap AS09C71 11.1V,6 cell Laptop Batteries,battery for GATEWAY AS09C71
)

Alienware praises the Area-51 m15x to be the first 15? notebook with Geforce 8800M GTX graphics. This is correct, but it is very likely that other producers will follow soon. Clevo for example, exhibited a 15.4? model at the last Cebit, which is planned to be equipped with a Geforce 8800 graphics card. We look forward to a direct competitor to the m15x, but it will play in a separate class until then.

The hardware of the Area-51 m15x reads like the wish list of a gamer to Santa Claus: nVIDIA Geforce 8800M GTX with 512MB GDDR3 video memory and Intel Core 2 Extreme processor with 2.8GHz and 6MB L2-cache are the fastest possible configuration of the m15x. This not only marks the top components of the m15x series, it is also the maximum possible performance of 15.4? notebooks. No series notebook is currently available that matches the performance of the Area-51 m15x.

A first glimpse at the impressive performance gives the 3D Mark benchmark tests. 15805 points in 3D Mark 05 and 9217 points in 3D Mark 06, catapult the Alienware notebook to the top. Even the former top dog in the ranking, the Dell XPS M1530, has to content itself with the second place far behind the m15x.

This result is not very surprising, and a comparison with various all-round multimedia notebooks seems almost pointless . The Alienware Area-51 m15x is a high performance machine, which would sacrifice everything in favor of performance. This idea was also applied when choosing the hard disk : A Hitachi ( HTS722020K9A300 ) with a speed of 7200r/min and a capacity of 200GB. The most outstanding feature is of course it’s performance. In the HDTune test it achieved excellent transfer rates of up to 70.5MB/sec and an exceptionally low access time of only 15.2ms. This result makes the hard disk one of the best of it’s class.

The m15x uses both available memory slots for RAM, which can hold up to 4096MB and supports dual-channel mode. Our test sample contained two 1024MB DDR2 PC5300 memory modules. Additionally, a Intel Turbo Cache module is available.

Apart from all the pushing to achieve maximum performance, the m15x also has a very interesting feature: The user can switch between the Geforce 8800M GTX and an integrated Intel graphics chip (BinaryGFX), by simply pressing the key combination FN+F7 [lenovo laptop battery]. Even though this makes a system restart necessary, it gives all the benefits of an integrated graphics card, like significantly lower temperatures, and thus quieter fans, as well as much lower energy consumption

The performance of the test sample convinces in the PCMark 2005 benchmark test as well. The m15x moves with 7669 points ahead to the top of the multimedia class once more. But that is not all. Even performance giants like for example the Dell XPS M1730 (still with Merom processor) are beaten by the m15x in this test. The main reason is the powerful Core 2 Extreme processor, which is fully utilised in this test.

This result is supported by the Cinebench R10 benchmark test. The Alienware Area-51 m15x manages top results in rendering and shading again. Actually, the Alienware m15x could also be used professionally for graphics and calculation intensive applications, but it’s main strength will always be games.

Probably the most important advantage of the Alienware m15x is the performance when running current games – at least this is what Alienware says. We obviously take this announcement as an invitation to immediately test Crysis performance on the Alienware m15x.

The Area-51 m15x provided a good impression of it’s performance. With a resolution of 1024×768 pixel and medium details, it achieves about 45 frames per second (fps) in the benchmark. Increasing the resolution to high details lets the result drop to below 30 fps. When playing the first single player level with 1024×768 and high details, it ran with 20 – 40 frames per second . The game was playable, but had frequent frame drops.

The m15x also achieved good results in the performance test of the real time strategy game World in Conflict with medium details (DirectX9). It managed an average of smooth 47 fps even on the maximum resolution of 1920×1200 pixels.
Changing to DirectX10 on the other hand, puts even the well equipped Alienware m15x under pressure. While it manages acceptable 31 frames per second with a 1024×768 resolution, it drops to 19 fps in native resolution (1920×1200).
This result changed in the practical test of a multiplayer game (2 vs. 2, map Seaside), which was sufficiently playable with 20-40 fps, despite DirectX10 and native resolution. But for LAN battles with more opponents it would be a good idea to reduce the resolution or detail level.

A mandatory test candidate is of course also the currently very popular multiplayer first person shooter Call of Duty 4 – Modern Warfare . The practical test of the first single player mission with a resolution of 1024×768, anti-aliasing deactivated, other settings on default, resulted in frame rates between 50 and 90 fps.
An increase of the resolution to 1920×1200 pixel reduced the frame rates slightly to 40-90 fps. But even with those settings the game was smoothly playable and looked excellent.

The Alienware Area-51 also successfully passed the Unreal Tournament 3 practical test. The observed frame rate (map Heat-Ray, details standard – level3) with a resolution of 1024×768 and native resolution of 1920×1200, stayed between 60-65 fps. Only an increase of the details to level 6 (world and textures), slowed the frame rate a bit down to 40-60 fps. But the game is still smoothly playable with those frame rates.

Our last test sample was Supreme Commander – Forged Alliance. In the practical test of the real time strategy game we played a four player multiplayer game with a resolution of 1024×768 and medium details, and observed a frame rate of 25-30 fps. The game was even with the maximum resolution of 1920×1200 pixel with 20-25 fps playable.

Note: Various forums discuss currently about a Bios update of the m15x, because the first m15x notebooks that appeared in the USA had apparently problems with heat sensors, which caused performance drops.
Our test sample already had the Bios version vX30P3, which should fix the issues and we also didn’t notice anything during the game tests. Just in case some users still have problems, Alienware offers another Bios update to version X32RC1. For more info and download, go here.

Depending on how the Area-51 m15x is run, it has two completely different noise levels. In office mode with little load it is possible to run it virtually silent. Two options make this possible: Either the stealth mode, which lowers performance of the m15x and can be activated by pressing a hot key above the keyboard, or by switching from powerful Geforce graphics card to the slow integrated Intel graphics chip. These options significantly reduce the noise level during undemanding tasks like internet surfing or typing, to quiet 32.8dB(A), which is an excellent result.

This quietness quickly changes to loud fan noise under load without any attempt to reduce performance and activated 8800M GTX graphics. The noise level of the m15x ranges, depending on game or application, from 43.3 dB(A) up to a maximum of 50.6 dB(A) if both cores and graphics card work at the limit. The fan noise can be described as unpleasant loud at this point. But gamers will probably be able to ignore the fan screaming, considering the performance the notebook offers.

The surface temperature also reflects the performance of the Area-51 m15x. Although the upper side of the base stays with 43.4°C at reasonable levels, the situation looks different on the bottom side around the central area, which heats up to a very hot maximum of 51.4 °C. It is thus important to always put the notebook on a flat and solid surface to guarantee proper airflow, especially if the notebook is often under load.

The m15x offers two speakers, located on the left and right above the keyboard, which produce clear sound. Although we wished for a bit more sonority and more bass for music replay, the sound quality is sufficient.

Although mobility isn’t so important for a gaming notebook like the Alienware m15x, it is actually capable of mobile use away from the power plug as long as only undemanding applications are used.

Important in this regard, apart from acceptable case size and weight, is the DELL Alienware M15X laptop battery life. The m15x has an ace up it’s sleeve that helps a lot – the option to switch to integrated graphics. The test of the maximum possible battery life (BatteryEater readers test) shows the difference: While the notebook runs for only 138 minutes with activated Geforce 8800M GTX graphics, despite having all energy savings activated (energy saving profile, stealth mode activated, minimum display brightness, WLAN and Bluetooth deactivated), it manages 223 minutes with the same settings after switching to integrated graphics.

Battery lifetime under load with dedicated graphics card (BatteryEater classic test) is only 77 minutes.
Acceptable is the laptop battery life when watching DVD’s. The m15x runs for 124 minutes with integrated graphics card, and is thus able to show a complete movie with average length.
Even better is the result in the practical WLAN test (integrated graphics,energy saving mode, brightness level 6 out of 7), with a battery life of 170 minutes.

Alienware makes with the Area-51 m15x a big step forward in the compact gaming segment. Somebody who is looking for high performance among 15.4? multimedia notebooks will quickly notice a distinct lack of competition for the m15x .

The biggest weakness of the Area-51 m15x is the case of the notebook. The plastic parts don’t convey high quality, neither regarding feel of the surface nor stability , not to mention the constant creaking noises when handling the notebook.
Although the m15x only offers a small amount of ports, everything a gamer needs is available. Especially the alignment of ports impressed during the test. So did the excellent keyboard, which is ready for a successful gaming career.

A strength of the Alienware Area-51 m15x is certainly the display, which offers a high resolution, good brightness and illumination, as well as excellent contrast and a matte surface, which prevents annoying reflections.

There is not much more to say about the performance. An increase in the 15.4? class would currently only be possible, if a producer managed to put two Geforce 8800M GTX graphics cards in one 15.4 inch notebook, which seems highly unlikely for several reasons (hp mini series laptop battery). The m15x offers thus awesome gaming performance, although a reduction of the detail levels in DirectX10 games might be necessary, if one wants to play at native resolution.

Another important point that speaks for the m15x is the low noise level in office and internet mode, because the notebook offers the possibility to switch between dedicated and integrated graphics , which significantly reduces the noise. This obviously doesen’t help in high performance mode, which results in a very loud notebook when using demanding programs.

The integrated graphics chip also helps to extend the battery life of the Area-51 m15x to acceptable levels, which makes mobile usage possible.

About Dell Alienware M15X Laptop Batteries

Stay unplugged longer with the new Dell Alienware M15X 7800mAh 5200mAh Li-ion dell Inspiron Battery. This 10.8V Rechargeable Li-ion battery can replace the original system battery or be used as a spare. Dell computer batteries life (and recharge times) will vary based on many factors including screen brightness, applications, features, power management, battery conditioning and other customer preferences.

Alienware announced a compact high performance notebook a long time ago. But although it was already available in the USA for quite a while, it is just now finally coming to Europe. The Area-51 m15x notebook makes Alienware the first producer that offers a 15? gaming notebook with a 8800 GTX graphics card and Intel Core 2 extreme processor. This is also the current maximum of what’s possible in the compact multimedia class. Compared with other Alienware models we tested so far, the Area-51 m15x looks very simple and discreet (fujitsu battery), at least as long as the various LED lights aren’t activated. The display lid and the base unit are kept in a silver-grey plastic frame. We especially liked the seamless workmanship of this part, which creates a compact impression of the notebook.

The geometrical and simple shape perfectly fits the colour scheme. The most outstanding details are firstly the two openings on the left and right of the keyboard, which contain the loud speakers, and secondly the central display hinge. But the Area-51 m15x becomes the center of attention only after turning on the LED illumination. The LEDs are very effective due to the unobtrusive case design, (Cheap FPCBP216 10.8V,3 cell Laptop Batteries,battery for FUJITSU FPCBP216) especially if other light sources are dimmed.

One can tweak the illumination of the Area-51 m15x with the Alien FX Lightning software in the command center. Various different colours or separate areas can be chosen for the light effects. The laptop distinguishes different areas of illumination, like the light pipe around the display in the shape of a small gap that emits light, the illumination of the hot keys, as well as the touch pad and keyboard. Our test sample had a keyboard without illumination however.

Another interesting gadget to personalise the m15x is the aluminum plate on the bottom of the notebook, on which up to 23 characters chosen by the soon to be owner (FUJITSU LifeBook M2010 laptop batteries), are engraved by laser. The text is translated into alien characters and also added to a foil which is put on the touch pad.

Ah yes, don’t forget the well known alien face on the display lid, which is illuminated as well. It starts to pulsate if the notebook is put into standby mode, which is also called “breathing” by Apple. The Alienware m15x unfortunately fails to do this smoothly, so that it looks more like it is clearing it’s throat.

We also had to clear our throat on closer inspection of the case, which makes a compact and robust impression at first due to the design, but clearly disappoints in the actual test (Cheap F310J 11.1V,9 cell Laptop Batteries,battery for DELL F310J). Holding the notebook, lifting it, or applying a bit of pressure, always results in creaky noises, which seem to be the norm with the m15x. Especially bad in this regard are the display and display hinges.

Although the display is with 12 millimeter not exactly slim, it seems to be very susceptible to any kind of pressure or twisting. Just opening and closing the display is apparently already too much for the notebook and results in loud creaking and squeaking. Furthermore, deformations and even colour changes on the display are noticeable. (Cheap a32-f82 11.1V,11.25V,6 cell Laptop Batteries, battery for ASUS a32-f82 ,brand new, 1 year warranty! Ship to most countries)

The hinge itself failed to make a good impression as well. Even though the resistance while adjusting the display is acceptable, the noise it creates and the wobbling of the display after it is put into the desired position is clearly not. Considering it is a compact notebook, which can be carried around, those problems are rather serious.

Especially the creaking noises while working with the notebook overshadow the impression of the m15x. The only average haptics of the plastic parts also fail to change this fact. The low quality is particularly hard to understand if one considers the current price of the Alienware Area-51m15x in our configuration of 2.799.- Euro. ( Replacement battery for ASUS A32-U6, 11.1 voltage, 4400 mAh, 6 cells, Li-ion Laptop Batteries)

The front and the back side of the notebook stay clear of connections. On the front right side of the notebook is a card reader ( 7in1 ) followed by an ExpressCard slot (54mm). Both slots are closed by well shaped flaps. Rubberplugs or plastic dummies are thus unnecessary.

Further back is a HDMI port, which allows a full digital transfer of image and video data. After that comes an USB 2.0 port and a Firewire 1394b (9-Pin) interface, which is a bit unusual for notebooks. Completely at the back is a Kensington lock.

The left side of the m15x is occupied by the power supply, LAN port, two USB 2.0 ports and audio connections (microphone, earphones). All those ports were located at the back half of the left side, which concentrates various cables and prevents annoying cable tangle. The Area-51 m15x has thus not only an extensive enough interface equipment, but also very good alignment of the available ports.

The DVD multi drive is located on the left side on the front. The SmartBay slot could also be equipped with another optical drive, like for example a Blu-Ray drive . Another possibility would be to put an additional hard disk or SQU-724 battery into the SmartBay slot of the m15x.

As opposed to other drives, the Optiarc AD-5540AD doesen’t have a reject button on the drive itself. Instead, it can be opened with the key combination FN+F8.

The m15x has also various integrated communication modules. The gaming notebook offers a Gigabit Ethernet module made by Broadcom for fast transfers over local networks, as well as a wireless LAN card by Intel, standard4965AGN. A Bluetooth 2.0 module provides wireless communication with various extra devices.

Alienware offers only a Kensington lock regarding security, but at least this allows to fix the notebook to a table or other heavy items on LAN parties, to prevent thieves from stealing the notebook.

Included in the shipment of our Alienware m15x test sample was a small leathercase containing the rather short user manual, a thin protection cover, recovery and driver CD ( Cheap UM09A75 11.1V,6 cell 9 cell Laptop Batteries,battery for ACER UM09A75 ), as well as Nero 7 Essentials. Further included was a mouse pad in Alienware design made by Func, which turned out to be very suitable for gaming in our tests ( in combination with a Logitech MX510 mouse ).

The Alienware Area-51 m15x offers a standard keyboard without additional number pad, which is not surprising for a 15.4 inch notebook. The lack of layout experiments, 18×18mm standard keys and the generous enter and space keys, make typing intuitive and adjustments unnecessary.

Typing on the keyboard, which offered a soft stroke and good resistance, was very pleasant as a result. Another positive feature is the quiet typing. The keyboard was also robust, even punctual pressure didn’t cause much deformation of the keyboard unit, which is especially handy when playing fast games that often lead to strong pressure on single keys in the heat of the moment. ( Replacement battery for ACER UM09A31, 11.10 voltage, 7200 mAh, 9 cells, Li-ion Laptop Batteries )

The individual keys seem a bit overloaded, because of the coloured border every key has, which emit light on models with integrated keyboard illumination (38.- Euro extra).

The touch pad is optically very well integrated into the look of the Alienware m15x. It is evenly built into the surrounding case and offers a single continuous touch pad button. The main weakness of the pad is the smooth surface. Alienware included two stickers with rough surface with the notebook that can be put on the touch pad, in order to improve handling. Most users will probably prefer the rough surface, which leads to the question why the pad wasn’t equipped with that surface from the beginning. Compared with the original surface, handling was clearly better after putting the sticker on the touch pad.

The single touch pad key was apparently also produced to please the eye, and not to be user friendly. The continuous button has a very large dead area in the middle (about a third of the total width!), and can only be pressed properly on the left and right edges (Cheap AL31-1005 10.8V,11.25V,6 cell Laptop Batteries,battery for ASUS AL31-1005). We thus highly recommend to use an external mouse, which should be the not a question for a real gamer anyway.

A touch sensitive panel above the keyboard of the m15x provides additional control of the notebook. The term “touch sensitive” is in our opinion not very accurate however, because the symbols require the finger to rest on them for a rather long time to actually react.
Especially annoying in this regard is the adjustment of the volume. A lot of patience is required to get the desired volume.

Alienware currently offers two different displays for the 15.4 inch models. They differ in supported resolution and type of display surface. The choice is between a 1440×900 pixel WXGA+ display with ClearView technology (glossy surface) and a 1920×1200 pixel WUXGA display with matte surface and HD compatible resolution. (ASUS Eee PC 1101HA laptop batteries)

Our test sample was equipped with the high resolution WUXGA display (LPL1801) and was instantly loved because of it’s non reflecting surface. This is unfortunately rare, since multimedia notebooks hardly ever offer matte surfaces. It is thus impressive that Alienware went against the common trend, and offers their high end display with an eye friendly surface.

Fears that the matte display might not be able to compete with glossy displays regarding brightness, colours or contrast, quickly disappeared after a couple of tests. The WUXGA display achieved a very good maximum brightness of 191.3cd/m2 in the central display area. The illumination of the panel is with 87.6% significantly above average.

The measured minimum brightness (black value) of the display was 0.37cd/m2. This, together with the maximum brightness of 191.3cd/m2, resulted in a maximum possible contrast of good 517:1 . Subjectively, the display is always sharp and with good contrast. (Cheap A32-F80 11.1V,6 cell Laptop Batteries,battery for ASUS A32-F80 ,brand new, 1 year warranty! Ship to most countries)

Rather untypical for a gaming notebook, but possible nonetheless, is the outdoor use of the Alienware Area-51 m15x . The dim display surface and the high brightness of the display allow outdoor usage with proper image quality.

The dim WUXGA display offers enough viewing angle stability in vertical and horizontal direction for a sufficiently large working area. The image does hardly change even if the horizontal viewing angle is very flat. Deviations from the optimal viewing angle in vertical direction have a bigger effect however, and overshadowing of the display happens quickly if the viewing angle gets flatter. But this shouldn’t be much of a problem in stationary use. (Cheap AS09C71 11.1V,6 cell Laptop Batteries,battery for GATEWAY AS09C71
)

Alienware praises the Area-51 m15x to be the first 15? notebook with Geforce 8800M GTX graphics. This is correct, but it is very likely that other producers will follow soon. Clevo for example, exhibited a 15.4? model at the last Cebit, which is planned to be equipped with a Geforce 8800 graphics card. We look forward to a direct competitor to the m15x, but it will play in a separate class until then.

The hardware of the Area-51 m15x reads like the wish list of a gamer to Santa Claus: nVIDIA Geforce 8800M GTX with 512MB GDDR3 video memory and Intel Core 2 Extreme processor with 2.8GHz and 6MB L2-cache are the fastest possible configuration of the m15x. This not only marks the top components of the m15x series, it is also the maximum possible performance of 15.4? notebooks. No series notebook is currently available that matches the performance of the Area-51 m15x.

A first glimpse at the impressive performance gives the 3D Mark benchmark tests. 15805 points in 3D Mark 05 and 9217 points in 3D Mark 06, catapult the Alienware notebook to the top. Even the former top dog in the ranking, the Dell XPS M1530, has to content itself with the second place far behind the m15x.

This result is not very surprising, and a comparison with various all-round multimedia notebooks seems almost pointless . The Alienware Area-51 m15x is a high performance machine, which would sacrifice everything in favor of performance.

In the HDTune test it achieved excellent transfer rates of up to 70.5MB/sec and an exceptionally low access time of only 15.2ms. This result makes the hard disk one of the best of it’s class.

The m15x uses both available memory slots for RAM, which can hold up to 4096MB and supports dual-channel mode. Our test sample contained two 1024MB DDR2 PC5300 memory modules. Additionally, a Intel Turbo Cache module is available.

Apart from all the pushing to achieve maximum performance, the m15x also has a very interesting feature: The user can switch between the Geforce 8800M GTX and an integrated Intel graphics chip (BinaryGFX), by simply pressing the key combination FN+F7 (lenovo laptop battery). Even though this makes a system restart necessary, it gives all the benefits of an integrated graphics card, like significantly lower temperatures, and thus quieter fans, as well as much lower energy consumption

The performance of the test sample convinces in the PCMark 2005 benchmark test as well. The m15x moves with 7669 points ahead to the top of the multimedia class once more. But that is not all. Even performance giants like for example the Dell XPS M1730 (still with Merom processor) are beaten by the m15x in this test. The main reason is the powerful Core 2 Extreme processor, which is fully utilised in this test.  http://www.cheap-laptop-batteries.com/fujitsu-laptop-battery.htm

The m15x also achieved good results in the performance test of the real time strategy game World in Conflict with medium details (DirectX9). It managed an average of smooth 47 fps even on the maximum resolution of 1920×1200 pixels.
Changing to DirectX10 on the other hand, puts even the well equipped Alienware m15x under pressure. While it manages acceptable 31 frames per second with a 1024×768 resolution, it drops to 19 fps in native resolution (1920×1200).
This result changed in the practical test of a multiplayer game (2 vs. 2, map Seaside), which was sufficiently playable with 20-40 fps, despite DirectX10 and native resolution. But for LAN battles with more opponents it would be a good idea to reduce the resolution or detail level.

The Alienware Area-51 also successfully passed the Unreal Tournament 3 practical test. The observed frame rate (map Heat-Ray, details standard – level3) with a resolution of 1024×768 and native resolution of 1920×1200, stayed between 60-65 fps. Only an increase of the details to level 6 (world and textures), slowed the frame rate a bit down to 40-60 fps. But the game is still smoothly playable with those frame rates.

Our last test sample was Supreme Commander – Forged Alliance. In the practical test of the real time strategy game we played a four player multiplayer game with a resolution of 1024×768 and medium details, and observed a frame rate of 25-30 fps. The game was even with the maximum resolution of 1920×1200 pixel with 20-25 fps playable.

Note: Various forums discuss currently about a Bios update of the m15x, because the first m15x notebooks that appeared in the USA had apparently problems with heat sensors, which caused performance drops.

The integrated graphics chip also helps to extend the battery life of the Area-51 m15x to acceptable levels, which makes mobile usage possible.
