Lots of little tweaks, but not much eye candy.
UNO cleans up the interface, giving everything the "sunken metal" style, instead of the combination of stripes, brushed metal, and sunken metal that OS X currently suffers from.
The Missing Sync keeps my PDA synchronized much more cleanly than Palm Desktop. Plus, the iSync conduit keeps my calendar and to-do lists synchronized between PDA and computer.

How to Choose a Good Laptop Battery and Get Longest Laptop Battery Life
How to choose a good laptop battery and get the longest laptop battery life available or hold your laptop battery more charging time.
Comparing various laptop batteries, you may wonder how to choose a good laptop with a good battery. And how to find the battery with the longest life available for your computer. That’s need a practical way to contrast them side by side. However, there is an important measurement of WHr(watt-hours) that determines the amount of laptop battery charging. The more WHr, the longer the battery will last between recharges. If your battery can produce one watt of power for 12 hours, then its rating is 12 WHr. Amp-Hours is another batteries’ charging measurement. The difference between WHr and Amp-Hours is that the watt as a measurement of power and the Amp as a measure of current.
The laptop battery provides a fixed voltage to your computer, measuring charge in watt-hours or amp-hours are equally valid methods. For instance, if your battery lasts for 20 watt-hours and always provides 10 volts, then it is valid to state your battery’s energy storage capacity as 2 amp-hours. Different batteries use different chemicals to store charges. Whether you’re talking about the rechargeable or non-rechargeable variety, all batteries work on the same basic principle: They are essentially a canister of chemicals that produce electricity.
For battery life, how long a laptop with a fully charged battery is able to run typical productivity apps, such as Microsoft Office, McAfee VirusScan, Adobe Photoshop and so on. The longest-lasting notebook according to some reports is the Lenovo (IBM) ThinkPad X60s. When configured with the high-capacity battery, its 8 hours, 16 minutes of life can get you through an entire workday. A Fujitsu Q2010 configured with an extended battery can last 7 hours, 38 minutes. The Dell Inspiron E1405 ran for 7 hours, 21 minutes; the Panasonic ToughBook 74 lasted 7 hours, 18 minutes; and the Lenovo ThinkPad R60 went for 6 hours, 25 minutes on a charge. The inexpensive HP Compaq nc2400 also performed well, clocking out after a lengthy 6 hours, 6 minutes.
After you choosing a good laptop battery, you will take care to make your battery life longer. Your laptop battery should never be stored in an area that drops below 50ÂºF (10ÂºC) or rises above 95ÂºF (35ÂºC); this means that your laptop should not be left in the car or in a storage area that is not climate controlled. Also, for extended storage of six months or more, the laptop battery should be discharged to 50% capacity and removed from the computer; a battery stored for an extended period of time at full capacity may lose the ability to charge fully, while a battery stored in a fully discharged state may never be able to charge again at all.
Modern laptop batteries tend to last three to five hours, depending on the power needs of the computer and the programs the user runs. Few things are as frustrating as when your laptop battery suddenly won’t charge fully or stops holding its charge for as long; when this happens, you’ll probably want to buy a replacement battery.

Laptop Batteries Replacement
The actual life of a laptop battery varies according to the usage habits of the laptop. If your laptop’s battery is experiencing shorter life cycles then you have to identify if it needs a replacement or not. Both original new and repaired laptop batteries are available online and at stores – better go for a new one.
The performance of a laptop’s battery depends upon its physical devices that require more electricity to operate. The hard drive, the floppy drive and the CD-ROM are the devices that sap up maximum power.
The computational programs and the calculation processes used by spreadsheet applications and database programs engage the processor to a greater degree as well resulting in large consumption of electricity. Other physical devices that consume greater strength of battery are audio and display devices. The display panel also consumes lot of electricity. The brighter the screen appears, the more electricity it is consuming. Video applications also have an intense effect on electrical needs, due to its usage of virtual memory. Laptop batteries, like other batteries, start discharging faster as they age.
Now if your laptop’s battery is giving frequent problems then go for a replacement. The best option is to go for online shopping portal like gadgets.in, and select suitable laptop batteries for replacement. There are laptop batteries of all makes that will replace the ageing battery of your laptop to make it all new and latest. The brand new battery will be proffered to you at a bargain price that will fit your laptop perfectly. The only thing that needs to be done is to correctly identify the model and serial number of your laptop battery and verify the Voltage and Amp rating prior to your purchase.
Before placing order for a replacement battery at Gadgets.in, view the model and serial numbers labeled on the bottom of the battery. For this, remove the battery from the laptop and you’ll see that the battery serial number is printed in black lettering beneath a barcode. After the removal of the ageing battery from the laptop do plug in the AC adapter to provide power to your laptop until a replacement battery arrives. After serial number verification, a new battery will be shipped to you promptly. All laptop batteries are built with the highest quality cells and appropriately meet the original manufacturer’s specifications.

We’ve been running on generator power here for the last few hours, and
the oil company stopped by to top off the reserve and give us the max
operational duration possible. Good times!
When this happened a year or so ago, we only had battery backup for
the servers. As the power in our laptop batteries faded, people
dropped out to work from other locations. That was a legitimate
disaster, while this is more of an adventure! Or at least a
distraction. This afternoon is sure to go quickly.

How to Re-calibrate laptop battery
How to Re-calibrate laptop battery
In the last artcile we know how to calibrate laptop battery. Now let me introduce some tips about re-calibrate laptop battery.
It is difficult to predict how long a laptop battery charge will last because each computer user has different habits and needs. The rate at which you use laptop battery power will determine how long you can use the battery of your laptop. You can re-calibrate your laptop battery if the battery’s life has gotten shorter over time. Your laptop battery might need a good calibration if it doesn’t seem to be getting the mileage that it should. How to re-calibrate laptop battery? The following paragraphs will give you the answer.
First put the laptop computer to sleep by turning off the screensaver and other power management settings of the computer. Then fully charge the computer and allow it to run all the way down until the computer shuts off automatically. Once the laptop battery has fully drained, charge it back up again and restore the screensaver and power management settings.
Re-calibrate your battery every month or so by fully charging, fully discharging, and then fully charging again. Basically to have a chance to re-calibrate your laptop battery is to turn off all power-saving features completely and then fully recharge them. If it doesn’t work for the first time then try two more full discharges and recharges.
The above way of re-calibrating thelaptop batteries works well with laptops using Ni-MH cells. But not with laptops using Li-Ion batteries because deep discharges will actually decrease the charge capacity and lifespan of Li-Ion cells. Moreover Li-ion batteries irreversibly lose approximately 20% capacity per year from the time of manufacture at a typical 100% charge level at 25deg.C, even when unused. Li-ion batteries irreversibly lose approximately 2%, 4%, 15% at 0deg.C, 25deg.C and 40deg.C respectively, when stored at 40% charge level. That is every deep discharge cycle decreases the capacity of the Li-ion batteries. As the Li-Ion batteries are chemical in nature, charging and recharging is not going to fix the problem once the chemical reactions stop happening. Therefore the best advice for re-calibrating the Li-Ion batteries is to store the battery at 40% charge if it kept unused for any unlimited period of time. Also don’t leave the battery in the laptop if you don’t use the battery or if you plug the laptop into outlet power.
You can also re-calibrate your laptop battery using Thinkpad T61 Battery Maximizer in order to maximize your laptop battery’s life. If your laptop has IBM ThinkPad Battery MaxiMiser and Power Management features installed, you can verify the condition of the laptop battery. You can check the status of your battery using the Battery MaxiMiser Gauge in the taskbar tray. The ThinkPad’s Lithium Ion battery pack that seems to be an intelligent battery uses a microprocessor to monitor its capacity. Then the microprocessor of the battery pack passes the information about the remaining battery capacity to the laptop. The laptop indicates the capacity with high accuracy.
Using the Dell Learning Utility, a modified version of a Win98 boot floppy, can also help you. Just place it in the floppy drive, and then turn on the computer. The re-calibration process is automated and takes about six hours to finish. This utility is available in different versions for different models. You can run the utility every two months.
If the laptop battery is still bad then it must have developed a memory that cannot be erased easily. If calibration doesn’t help, then it is the right time to purchase another battery.
Long and beefy overview and review of the Acer TimelineX 4820TG laptop. I do run some tests like 3dMark Vantage and Prime95 to measure its power. I also run CounterStrike Source to see some basic graphical performance on it. It is a light, powerful laptop that costs around 750-800 Dollars. Its fast and has a very good battery life. It can run most games smoothly, although I haven’t tried more stressful games. Overall, it is a very good laptop that is good for school, light surfing, work and gaming. It is a winner in my book.

How to Revive a Dead Laptop Battery
Bring a seemingly-dead laptop battery back to life, to a usable condition, although not quite like-new. It could be almost as good as a replacement laptop battery and a lot cheaper than a universal external laptop battery. Using a Freezer, the same place you put your frozen peas and TV dinners, you could restore a dead laptop battery.
Simply follow the instructions below and save yourself some money. It will only cost you the time it takes to complete the list below. So do yourself a favour and do it yourself.
1. Place a dead laptop battery in a completely sealed plastic bag. 2. Place the bag and battery in your freezer for between 11-14 hours. 3. Remove the bag from your freezer and allow the battery return to room temperature after taking it out of the bag, this is very important. 4. If your laptop batteries are still damp dry it using a cloth or towel. 5. Place your once dead laptop batteries back into your laptop. 6. Now completely charge your battery then leave it on to discharge it completely. Repeat this step at least 3-4 times. 7. Your dead battery should be much more usable, if not totally restored.
Well, consider replacing the internal batteries at a fraction of the cost of the alternatives methods. So, do not condemn your laptop battery to the recycle bin just for the moment. Using this method could see you saving yourself between 30-90% of the cost of your replacement laptop battery. This cheap alternative method is to substitute the batteries inside the battery pack with a brand new set. You first need to remove the battery pack from your laptop. You will then need to open the battery pack carefully, a screwdriver should do the job. Inside you will be confronted with several batteries and a host of wires. A word of warning, if any battery is leaking proceed carefully. If you are not sure then do not continue.
Now you will need to make a note of the type of laptop battery you have and exactly, I repeat exactly how it is connected (wired) to each other. Just to be sure you could test your old batteries with a millimeter or similar device to see just what state they are in. If you touch these leaking batteries then dispose of them appropriately and then make sure you wash your hands thoroughly and you’re back in business. After confirming that they are in fact dead laptop batteries you will need to order some replacement batteries. To do this ensure the replacement have a higher milliamp value than the old ones, just slightly. When you receive your replacement laptop batteries put the new batteries in the correct positions and replace the wiring so you can do the necessary soldering. Make sure to use the appropriate safety equipment and double check all connections are correct. Once your laptop batteries are in place and everything confirmed you should test them with your millimetre to ensure they are working as expected.
Reassemble the laptop battery pack and seal it properly. Re-install the laptop battery into your laptop and start enjoying your laptop’s new lease of life.
You might consider the limited list below that could also benefit from any of the methods above.
