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 Hiberntion 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
CAUTION: 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.
