Managing Low-Battery Conditions
Some low-battery condition alerts and system responses can be
changed in the Power Options window of the operating system.
The information in this section describes the alerts and system
responses set at the factory. Preferences set in the Power Options
window do not affect lights.
Identifying Low-Battery Conditions
This section explains how to identify low and critical battery
conditions.
Low-Battery Condition
When a battery pack that is the sole power source for the
notebook reaches a low-battery condition (5 percent of a full
charge), the battery light blinks.
Critical Low-Battery Condition
If a low-battery condition is not resolved, the notebook enters a
critical low-battery condition (3 percent of a full charge).
In a critical low-battery condition:
■ If Hibernation is enabled and the notebook is on or in
Standby, the notebook initiates Hibernation.
■ If Hibernation is disabled and the notebook is on or in
Standby, the notebook remains briefly in Standby, then shuts
down and loses your unsaved work.
To verify that Hibernation is enabled, be sure that the Enable
Hibernate Support check box on the Hibernate tab is selected. To
access the tab select Start > Control Panel > Performance and
Maintenance > Power Options icon.
