Identifying low battery levels

When a battery that is the sole power source for the computer reaches a low battery level, the battery

light blinks.

If a low battery level is not resolved, the computer enters a critical battery level, and the battery light

blinks rapidly.

The computer takes the following actions for a critical battery level:

●

If Hibernation is enabled and the computer is on or in the Sleep state, the computer initiates

Hibernation.

●

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.
