Resolving Low-Battery Conditions

Ä
CAUTION: If the notebook has reached a critical low-battery
condition (1 percent of a full charge) and has initiated Hibernation,
do not restore power until Hibernation is complete. Hibernation is
complete when the power/standby light turns off.
When External Power Is Available
Select 1 of the following options:
■
Connect the AC Adapter.
■
Plug an optional Automobile Power Adapter/Charger into the
notebook and into a vehicle cigarette lighter receptacle.
■
Plug an optional Aircraft Power Adapter into the notebook
and into the in-seat power supply available on some
commercial aircraft. (An optional Aircraft Power Adapter
can run the notebook but cannot charge a battery pack.)
When a Charged Battery Pack Is Available
Turn off the notebook or initiate Hibernation, insert a charged
battery pack while the notebook is off or in Hibernation, then turn
on the notebook.
When No Power Source Is Available
Initiate Hibernation. Or, save your work, then shut down the
notebook.
When the Notebook Cannot Exit Hibernation
If the notebook lacks the power to exit Hibernation:
1. Insert a charged battery pack or connect external power.
2. To exit Hibernation, briefly press the power button.
