Power Managing Low-Battery Conditions You can change some low-battery condition alerts and system responses using 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 battery or power 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, and 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. Be sure that the Enable Hibernate Support check box is selected. Hardware and Software Guide 3-19
