Tips for maximizing battery discharge time:

●Lower the brightness on the display.

●Remove the battery from the computer when it is not being used or charged.

●Store the 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.
