Main battery
Any laptop computer has a battery pack which provides power to the laptop while it’s not connected to the wall-plug through AC/DC power adapter. Laptop batteries come in many different shapes and they are model-specific.
The laptop battery life depends upon many conditions and circumstances: screen brightness, intensity of running programs, the temperature of the working environment, etc…
The same battery could last longer in the same laptop if you optimize the power usage settings in the control panel. You can lower screen brightness, reduce CPU processing speed, chance cooling method, and other settings available on your laptop. Some of these settings could be changed only through the manufacturer’s power management software.
In most laptops the main battery connects directly to the system board.
TROUBLESHOOTING LAPTOP BATTERY PROBLEMS.
Let’s say your laptop stopped running on the battery power. It works fine from the AC adapter but shuts down as soon as you unplug the adapter. If that’s the case, try reconnecting the main battery. Remove it from the laptop and install back. It’s possible the battery is not making good connection with the motherboard.
Unfortunately, the only reliable way to test the main battery is replacing it with another known good battery.
If the laptop cannot detect the battery, even though it’s installed, try replacing the battery with a new one. If you still have the same issue, most likely there is a problem wiht the system board.

I have a laptop Dell 2650, when i unplug the power cord, the battery is detected the laptop works fine for a few minutes and when the discharging level reaches 95%, the laptop turns off immediately yet i set it to get into hibernation when the battery level clocks 30%.Thus it misses hibernation and just turns off
What would be the problem. Cause initially the battery was discharging upto 0% then it hibernates.
Thanks

hazel,
That’s a really strange problem. Are you getting error message? How exactly the flash drive fails?
Did you try flash drives in any other working computer?

Hello, just want to share a problem with my laptop. It only accepts flashdrive which I bought from the US. But when I came back here in the Phils, when I tried inserting other devices like flashdrives from my bro,card reader,and other devices,they don’t seem to work in my notebook. By the way, it’s OS is Windows Vista. It’s bothering me already since I can’t copy files from other devices. What’s the possible cause for this?Hope you can answer. Thanks..:)

Qadir,
Try this. Turn off the laptop, remove the battery, unplug the AC adapter and wait for a few minutes. Test the laptop.
Take a closer look at the battery contacts, it’s possible overtime they got oxidized and will not make proper connection with the motherboard.
Make sure the battery is seated correctly.

I want say thank you Tim with comment 3. I had same laptop like yours Satellite A105. Bought it I think 4 years ago and it’s not in warranty. My battery did not hold charge for more than 30 minutes.
I checked my battery on website you gave us and called to Toshiba.
They will replace my battery for free because the recall.
Thank you for saving my money!

Jim, I had same exact problem with the battery in my laptop. You have to buy a new battery, that’s what I did and it works fine now.

I hope you know the answer.
The battery in my laptop charges fine and goes to 100%. After I unplug the adapter, the battery starts discharging normally until it reaches about 85% and after that the cahrge drops to 0% in a few minutes.
I plug the adapter back in and the battery starts charging normally again and charges to 100%. When I unplgu the adapter everythign repeats.
What is wrong with my laptop?

I just want to share.
I had a 3 year old Toshiba Satellite A105 laptop and the battery was dying. I was searching for a new battery pack for my laptop and found this page about battery recall in Satellites A105and Tecra A7 laptops. http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/bulletin.jsp?soid=1788033
I was going to buy a new battery but Toshiba replaced it at no charge! And yes, my laptop is not in warranty.

girl_M,
Your laptop will run longer without recharging with a battery with higher mAh. I would order the 4500mAh battery.

I’m replacing laptop battery but not sure which one to order. I found two compatible batteries and everything looks exatly the same but one of them says 2000mAh and another one 4500mAh. Which one to order? Thanks.
