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
(Start > Control Panel > Performance and Maintenance > Power options). 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 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.
