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:
●
Lower the brightness on the display.
●
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.
The computer must be connected to external power for Battery Check to work properly.
