To recharge a battery

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.
2. Connect the ac adapter to the OmniBook's right side, as shown.
