On the battery pack
1. Remove the battery pack from the notebook. See the
“Getting Started with Your Notebook” chapter in this guide.
2. Press the contact pad on the side of the battery pack. The
number of lights that turn on indicates the remaining charge
(each light represents 20 percent of a full charge).
To Respond to a Low-Battery Warning
The notebook automatically alerts you when the battery power
drops to a critically low level. The notebook first emits a
high-pitched beep or displays a warning message. Then, if you
do not restore power within a short time, the notebook goes into
Hibernation.
After the notebook enters Hibernation in this way, you will not
be able to turn it on again until you restore power by doing one
of the following procedures:
Replace the battery pack with a charged one.
Plug in the AC adapter.
NOTE: If you plug in the AC adapter, you can continue to work
while your battery pack recharges.
