Hi,
Check with System maker's Support, their on-line documentation and drivers, and their forums
(if any) for known issues. Some maker's have issued BIOS and other updates to help with battery
problems.
Control Panel - Power Options - Power Plans - Change plan Settings - check the Advanced
Settings for drain and usage settings (this is how much to be used and not how much or how

Check with the support of the system maker and many of them have on line forums.
