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

Low-Battery Condition
The battery light blinks in a low-battery condition. The
low-battery default is 10 percent of a full charge, but is
programmable by the user.
Critical Low-Battery Condition
If a low-battery condition is not resolved, the notebook enters a
critical low-battery condition; the default is 3 percent of a full
charge but is programmable by the user.
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.
Hibernation is enabled at the factory. To verify that Hibernation
has not been disabled, 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.
