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 16).
–or–
Replace the battery with one that is charged (see "To install the battery" on page 15).
If you plug in the AC adapter, you can continue to work while your battery recharges.
