Monitoring Battery Power
The primary source of power for the OmniBook is its rechargeable battery pack. You can
use the ac adapter to recharge the battery—or to run on ac power to preserve the battery.
Important
Running external connections is a power-intensive operation that significantly shortens
the length of a battery session. Whenever possible, connect the ac adapter when using
external connections.
In addition to the replaceable battery, there is a permanent, internal backup battery, which
recharges whenever the OmniBook is on or connected to ac. It maintains certain internal
settings, such as the clock.
