Identifying Low-Battery Conditions

Low-Battery Condition

When a battery pack that is the only power source for the notebook reaches a low-battery condition, a text warning message is displayed.

If you try to start the notebook from a battery pack that is in a low-battery condition, the battery light blinks.

Critical Low-Battery Condition

If a low-battery condition is not resolved and the amount of charge remaining in the battery pack continues to drop, the notebook eventually enters a critical low-battery condition. If the notebook is on or in standby when a critical low-battery condition is reached:

■If hibernation is enabled, the system initiates hibernation. Some unsaved work may be lost.

■If hibernation is disabled, the notebook remains briefly in standby, and then shuts down. All unsaved work is lost.

The battery light blinks until the notebook shuts down.

Hibernation is enabled by default. To verify that hibernation remains enabled:

»Select Start > Control Panel > Performance and Maintenance > Power Options > Hibernate tab.

If hibernation is enabled, the Enable hibernation check box is selected.
