Windows 7: New Battery stops charging at 45%

New Battery stops charging at 45%

Hi,

I hope somebody can help me. I have just purchased a new battery for my Fujitsu Amilo pi 3660 notebook.

I have tried so many times to charge it. I have fuilly discharged it and recharged it. I have installed and reinstalled drivers. No matter what I do, it stops charging at exactly 45%.

I know the battery is sound and the problem is a software issue. Does anyone know how to change this cap on the battery.

BTW The new battery has slightly, (very) more capacity. This has not been a problem in other laptops, but this Fujitsu certainly caps the charge at 45%

Please can anybody help. You have no idea the hours I have wasted trying to resolve it.

Many thanks Ceira.

How much more capacity does it have? if it is around double the original capacity, then it's the BIOS that still thinks the battery is the old one. Try to go in BIOS options and see if you can change something, and try "resetting to factory defaults" (the bios, not windows 7).

Remove all system utilities that came preinstalled on that machine (those that could interfere with charging, like power utilities and assistants and whatnot, not programs like photoshop or whatever)
