Managing Low-Battery Conditions

The information in this section describes default alerts and system responses.

Identifying Low-Battery Conditions

When the battery pack is the only power source for the notebook and drops to 10 percent of a full charge, the notebook has reached a low-battery condition. A text warning message appears on the screen.

If a low-battery condition is not resolved and the amount of charge remaining in the battery pack continues to drop, the notebook eventually enters a critical low-battery condition. Then, if the notebook is on or in Standby:

■If Hibernation is enabled, the system initiates Hibernation. Unsaved work may be lost.

■If Hibernation is disabled, 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.

Resolving Low-Battery Conditions

ÄCAUTION: If the notebook has reached a critical low-battery condition and has begun to initiate Hibernation, do not restore power until Hibernation is complete. When Hibernation is complete, the power/standby light turns off.

If external power is available, connect the notebook to the external power source.

If a charged battery pack is available, shut down the notebook or initiate Hibernation. Insert a charged battery pack, then turn on the notebook.

If no power source is available, save your work. Then initiate Hibernation or shut down the notebook.
