Power Identifying Low-Battery Conditions When a battery pack that is the only power source for the notebook reaches a low-battery condition, the battery light blinks. If a low-battery condition is not resolved, the notebook enters a critical low-battery condition. 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: 1. Select Start > Control Panel > Performance and Maintenance > Power Options > Hibernate tab. 2. Make sure that the Enable hibernate support check box is selected. Resolving Low-Battery Conditions Ä CAUTION: If the notebook has reached a critical low-battery condition and has initiated hibernation, do not restore power until the power/standby light is turned off. When External Power Is Available To resolve a low-battery condition when external power is available, connect the AC adapter or an optional automobile or aircraft adapter. 2-26 Hardware and Software Guide
