When battery power is critically low, the battery indicator in the status panel appears
empty and starts to blink. A warning beep reminds you to save your work. (Press

be able to restart until you restore power by one of the following actions:
•
Plug in the ac adapter.

•
Replace the main battery with one that’s charged.

To recharge a battery
Charging the battery takes about 1.5 hours when the computer is off or suspended,
or about 2.2 hours when the computer is in use.
C A U T I O N The ac adapter is normally warm to the touch whenever it’s plugged into an ac
outlet. The OmniBook is normally warm while it’s charging. Don’t charge it in a
briefcase or other confined space as this may cause the battery to overheat.
1. Connect the power cord to the ac adapter, then plug the cord into an ac outlet.
The indicator light on the ac adapter shines when the adapter is on.
If the ac adapter does not light, make sure that cord is not damaged. Also ensure
that the battery has been inserted correctly into the OmniBook.
2. Connect the ac adapter to the OmniBook’s left side, as shown in the following
illustration.
