To prolong battery life and optimize the accuracy of battery charge displays, follow these
recommendations:
●
If you are charging a new battery, charge it fully before turning on the Slate.
NOTE:
the far right of the taskbar, may show 100 percent charge before the battery is fully charged.
●
Allow the battery to discharge below 5 percent of a full charge through normal use before
charging it.
●
If the battery has been unused for one month or more, calibrate the battery instead of simply
charging it.
Maximizing battery discharge time
Battery discharge time varies depending on the features you use while on battery power. Maximum
discharge time gradually shortens, as the battery storage capacity naturally degrades.
Tips for maximizing battery discharge time:
●
Decrease the brightness on the display.
●
Store the battery in a cool, dry location.
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.

●
If Hibernation is disabled and the Slate is on or in Sleep, the Slate remains briefly in Sleep, and
then shuts down and loses any unsaved information.
