Managing Low-Battery Conditions

It is important to respond to a low-battery or critical low-battery
condition. This section describes default battery settings and
ways to protect your work in a low-battery condition.

Identifying a Low-Battery Condition

When the battery pack is the only power source for the notebook
and drops to 5 percent of a full charge, the notebook has reached a
low-battery condition. When this condition occurs, the battery
light blinks and a text warning message is displayed.
The Power Options utility allows you to redefine a low-battery
condition, set audio warnings, and change other power defaults.
For details, see the "Power" chapter in the Software Guide on the
Documentation Library CD.

Identifying a Critical Low-Battery Condition

If you do not resolve a low-battery condition, the notebook enters
a critical low-battery condition. By default, the notebook defines
a critical low-battery condition as 3 percent of a full battery
charge remaining.
The battery light continues to blink and:
■
If Hibernation is enabled (the default setting) and the
notebook is on or in Standby, the system initiates Hibernation
and saves system memory to the hard drive. Unsaved work
might be lost.
■
If Hibernation is disabled and the notebook is on or in
Standby, the notebook remains briefly in Standby, then
shuts down. The power/Standby light turns off, and the
notebook cannot save system memory to the hard drive.
