Identifying low battery levels
When a battery that is the sole power source for the computer reaches a low or critical battery level,
the power meter icon on the Windows desktop shows a low or critical battery notification.
NOTE: For additional information about the power meter, refer to Using the power meter and power
settings on page 37.
The computer takes the following actions for a critical battery level:
●
If Hibernation is disabled and the computer is on or in the Sleep state, the computer remains
briefly in the Sleep state, and then shuts down and loses any unsaved information.
●
If Hibernation is enabled and the computer is on or in the Sleep state, the computer initiates
Hibernation.
