Managing Battery Power
The OmniBook conserves power by using Advanced Power Management
(APM), software that controls battery charging and power drain.
The OmniBook provides several safeguards so you won’t be surprised by a
dead-battery condition, including the following:
♦
The battery status indicator shows the remaining battery charge.
♦
Built-in warnings are displayed for low battery conditions.
♦
The OmniBook automatically turns off when the battery charge gets too
low—your session continues when you start recharging the battery or
insert a fresh battery.
Data on any of the drives is not affected by a low battery—unless the battery
runs down completely while writing data to the drive, or if the battery in a PC
RAM card is also low.
The OmniBook uses Advanced Power Management (APM) to conserve
battery power. You can take steps to optimize your battery operating time. This
section describes how to
♦
Save battery power.
♦
Set time-outs.
♦
Get the most from your battery.
♦
Create the hibernation partition.
