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 Standby, the computer initiates Hibernation.

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