in the computer are fully charged. If the computer is not plugged into an external power source,
the light stays off until the battery reaches a low battery level.

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 > System and Security > 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
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.
