Maximizing battery discharge time
Battery discharge time varies depending on features you use while on battery power. Maximum
discharge time gradually decreases as the battery storage capacity naturally degrades.
Tips for maximizing battery discharge time:

Remove the battery on the computer when it is not being used or charged, if the computer
contains a user-replaceable battery
Store the user-replaceable battery in a cool, dry location.
Select the Power saver setting in Power Options.
Managing low battery levels
The information in this section describes the alerts and system responses set at the factory. Some
low-battery alerts and system responses can be changed using Power Options in Windows Control
Panel. Preferences set using Power Options do not affect lights.
