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.
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 begins blinking 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.
