Using Battery Power
Setup Guide 53
To respond to a low-battery warning
The OmniBook automatically alerts you when the battery power drops to a critically
low level. First you will hear a high-pitched beep. Then, if you have not taken
restorative action within a short time, the system hibernates.
You won’t be able to turn the computer on again until you restore power by one of
the following actions:
•
Plug in the AC adapter (see "To connect AC power" on page 20).
–or–
•
Replace the battery with one that is charged (see “To install the battery” on page
19).
Note
If you plug in the AC adapter, you can continue to work while your battery
recharges.
