When Laptop Battery Won’t Hold a Charge, how to do?
Most laptop batteries have a life expectancy of two years or 400 to 450 charge and discharge cycles. After this time, the battery may lose the ability to charge or to hold a charge for substantial periods of time. When this happens, it’s likely the battery needs replacement. However, troubleshooting can narrow the problem and ensure you are not wasting money on a battery replacement. toshiba laptop battery

There’s absolutely no way to do this justice without a tripod. This is a hand-held HDR using 5 images, 0.7EV apart from each other. So the colours are a bit smeared due to my slight hand motions. This church is the most breathtaking place I have ever seen.
If you’re wondering where I am… I’m back home, but my laptop with all of my photos from France has malfunctioned. The power adaptor will not power the laptop up anymore, and the batteries have run dry. So until I get a replacement, I will be posting nothing.
See you when I get the laptop back from the shop.
Charge a New Laptop Battery
Laptop batteries are notorious for dying out and losing charge quickly. If you treat your battery with the utmost care, you’ll have success in getting the most out of it. Know what type of battery you have and understand how it needs to be treated in order to perform. But first make sure you charge your laptop battery properly when using it for the first time.
Your new laptop battery comes in a discharged condition and must be charged before use (refer to your computer manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity.
When charging the laptop battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Simply remove the battery from the computer and repeat the charging procedure.
It is important to condition (fully discharge and then fully charge) the toshiba laptop battery every two to three weeks. Failure to do so may significantly shorten the battery’s life (this does not apply to Li-ion batteries, which do not require conditioning). To discharge, simply run your device under the battery’s power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your user’s manual.
First Time Charging
The amount of time it takes for your toshiba PA3534U-1BRS battery to fully charge depends on many factors, like your battery type and operating system. Many newer laptops will charge in 15 to 20 minutes, while others can take a few hours.
When you’re charging your battery for the first time, charge it fully before using your laptop. You may have to go through a battery cycle a couple times before your battery begins performing at its maximum capability. To do this, charge your battery fully, let it discharge to about five percent, and then fully charge it again.
Charging your battery for the first time is just the beginning. You must give your battery the utmost attention if you want to get the best out of it.
Never let your battery stay connected to a power source once it’s fully charged. This leaves the battery in a constant state of charging up, ultimately reducing its life cycle. Once your battery is charged, unplug your laptop AC adapter, or remove the battery.
When you’re storing a battery, expect it to naturally discharge itself about 10 to 15 percent over a four-month period. It’s best to fully charge your battery before storage. When you are storing your battery, you should plug it into your laptop every month or so and let it discharge and charge back up a little. Make sure you fully discharge and charge your battery every three or four months.
Maximizing Battery Performance
There are several tips to preserving your battery life and achieving its maximum performance. One simple thing users can do is turn down the brightness of their screen as low as possible. Another option is to check your battery performance tool installed on your computer. This will allow you to control exactly how you want your battery’s power to be used.
Preventing the Memory Effect – Keep your battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-ion batteries which do not suffer from the memory effect.
Keep Your Batteries Clean – It’s a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and your portable device.
Exercise Your Battery – Do not leave your battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure described above.
When you’re using your laptop, try not to run many programs at once. This will kill your battery life quickly, and also try to close down any programs that you aren’t using at the moment. Go into your computer’s settings and adjust features like screen savers, sleep/hibernate mode and auto-save functions to suit your desire.
If you don’t plan on using the battery for a month or more, we recommend storing it in a clean, dry, cool place away from heat and metal objects. Ni-Cd, NiMH and Li-ion batteries will self-discharge during storage; remember to break them in before use. Sealed Lead Acid (SLA) batteries must be kept at full charge during storage. This is usually achieved by using special trickle chargers. If you do not have a trickle charger, do not attempt to store SLA batteries for more than three months.
For Notebook Users – To get maximum performance from your battery, fully optimize the notebook’s power management features prior to use. Power management is a trade off: better power conservation in exchange for lesser computer performance. The power management system conserves battery power by setting the processor to run at a slower speed, dimming the screen, spinning down the hard drive when it’s not in use and causing the machine to go into sleep mode when inactive. Your notebook user’s guide will provide information relating to specific power management features.

Troubleshooting Dell Laptop Battery Does Not Charge Problem
A laptop utilizes a battery for power when it is not plugged into an electrical outlet. Dell Inspiron laptops use rechargeable lithium ion batteries. The laptop battery has a life expectancy of 12 to 24 months, depending on several factors, such as care and battery usage. If the battery is not holding a charge, it may be damaged or dead and need to be replaced. Prior to replacing the battery, you should troubleshoot it, just to be sure.
Attempt to fully charge the battery. Plug the power adapter into the laptop and allow the battery to charge overnight.
Turn the Dell Insprion laptop off. Unplug the laptop from the laptop power adapter.
Flip the laptop upside down so the battery is visible. The battery is located on the underside of the laptop.
Slide the Dell Inspiron 1520 Laptop Battery lock switch and hold it in place. Lift the battery upward for removal. Once removed, release the battery lock switch.
Examine the battery. Look for signs of damage to the battery. If you notice any damage, the battery must be replaced.
Clean the battery contacts. Dip a cotton swab in rubbing alcohol and clean the battery contacts and the contacts inside the battery bay to remove dust.
Check the battery (Dell Latitude D830 Laptop Battery) charge. Press the “Status” button on the back side of the battery. It has five lights that will display how charged the battery is. Five lit lights indicates a full charge, one lit light indicates a low charge and no lit lights indicates the battery has no charge. If the battery has no charge, it is dead and needs to be replaced. If the battery does indicate it is partially or fully charged, continue troubleshooting.
Recalibrate the battery. Place the battery back in the laptop. It will just pop into place. Turn the computer on and allow the computer to run on battery power until the battery dies. Once the battery dies, plug the power adapter into the computer and allow the battery to fully charge again. Remove the battery and check the battery charge. If it still has not fully charged, you need a new battery.

Charge A Laptop Battery Without A Charger
Without your AC charger/adapter, you may feel like your laptop is next to worthless. After all, not only do you not have a way to charge the battery in your laptop, you don’t even have a way to run your computer via a wall outlet. While new technologies are being developed every day in the area of mobile power solutions (including Intel’s research into wireless electrical transmissions), there aren’t many current alternatives to charging your laptop battery without a charger. If your problem is that you are without your original charger (which is what normally comes with a new laptop), here are some workarounds you can try that will keep your laptop humming. Keep in mind, though, that they cost money and require an advanced purchase, in which case it may be just as economical and convenient to buy a new charger from your laptop’s manufacturer.
Use a universal power adapter. This is perhaps the most obvious solution to your battery woes. Readily found at most retail outlets that carry electronics, a universal power adapter can range anywhere in price from to 0 (or more, depending on how fancy you get). The adapter comes with multiple tips, one of which will likely fit your laptop’s charging port. When plugged in, the adapter will not only power your laptop, but will charge its battery as well.
Use a universal auto/air adapter. If you’re the road-warrior type who spends more time in your car than at a desk, this might be the sensible solution for you. An auto adapter is similar to a regular power adapter, except it has a modified end that plugs into your car’s cigarette lighter. The adapter will keep you powered while in your car (or inflight if it’s a combination adapter), and will simultaneously charge your laptop so you’re ready for those occasions when you do have to leave your car or plane for the real world.
Buy an external laptop battery charger. These are standalone devices that do not plug into your laptop. Rather, you take the battery out of your laptop, attach it to the charger, plug the charger into an electrical outlet, and rejuice your battery that way. When fully charged, you reinsert the battery back into your laptop. External chargers are usually brand and model specific, so make sure you get one that matches your laptop’s specs. One advantage to an external battery charger is that you can charge spare batteries without tying up your laptop.
