Managing Battery Power

Managing Battery Power
The OmniBook conserves power by using Advanced Power Management
(APM), software that controls battery charging and power drain.
If you're using Windows 95 or 98, APM is preinstalled on the
OmniBook.
If you're using Windows NT 4.0, you'll need to install APM (see chapter
6 for instructions).
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.
A low battery does not affect data on any of the drives—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.

To save battery power

Follow these suggestions to conserve battery power.
•
Plug in the ac adapter, especially while using the floppy disk drive, a
CD-ROM drive, or any external connections.
•
Put the OmniBook in Suspend mode whenever you are not using it for
a short while: close the lid, or press the blue power button for
approximately 1 second, or select Start menu, Suspend.
•
Put the OmniBook in Hibernate mode whenever you want to save your
current session, but will not be using the computer for several hours or
more (Fn+F12).

Shut down the OmniBook whenever you will not be using it for
several hours or more. Click Start, Shut Down. The current session is
not saved.
