Managing Low-Battery Conditions

Some low-battery condition alerts and system responses can be changed in the Power Options Properties window of the operating system. The information in this chapter describes the alerts and system responses set at the factory. For information about setting preferences in the Power Options Properties window, refer on this CD to the Software Guide, “Power” chapter, “Setting Power Preferences” section.

Identifying Low-Battery Conditions

The notebook has alerts for 2 types of low-battery conditions: a low-battery condition and a critical low-battery condition.

Low-Battery Condition

When a battery pack that is the only power source available reaches a low-battery condition (10 percent of a full charge), the battery light flashes.
