Help toshiba satellite c655 Consider Replacing Your Battery

Well, in my opinion you should definitely try a new battery..

Of course it would be better to test this before purchasing a new battery…
Try these suggestions I got from TOSHIBA Supports Forum..
1) Check whether the BIOS version was up to date, which it was (BIOS version 2.00) as confirmed by clicking F2 on start up.

2) Uninstall the old version of the program "Toshiba Value Added Package" then go to the mytoshiba.com.au site, enter the laptop model/part number and download the latest Value Added Package, followed by a reboot.

If all the updates (BIOS, VAP, etc…) didn’t help then a new battery should be tested.
