Identifying Low-Battery Conditions

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

If a low-battery condition is not resolved and the amount of charge remaining in the battery pack continues to drop, the computer eventually enters a critical low-battery condition. If the computer 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 computer remains briefly in standby, and then shuts down. All unsaved work is lost.

Hibernation is enabled by default. To be sure 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.

Resolving Low-Battery Conditions

ÄCAUTION: To reduce the risk of losing information when the computer reaches a critical low-battery condition and has initiated hibernation, do not restore power until the power lights are off.

To resolve a low-battery condition:

■If external power is available, connect the computer to the external power source.

■If a charged battery pack is available, shut down the computer or initiate hibernation. Insert a charged battery pack, and then turn on the computer.

■If no power source is available, save your work. Then initiate hibernation or shut down the computer.
