Recharging and Replacing Batteries
You can use the ac adapter to recharge the battery—and to run on ac power to
preserve the battery. The OmniBook conserves power by using Advanced Power
Management (APM), software that controls power drain.
Data on any of the drives is not affected by a low battery. However, the data could
be affected if the battery runs down completely while writing data to the drive.
In this section you’ll learn how to
• Recharge the battery or run on ac power.
• Replace the battery.
To recharge the battery or run on ac power
•
Plug the power cord into the adapter, then into a grounded ac outlet.
• Insert the adapter plug into the socket at the right-rear corner of the OmniBook.

Caution
Use only an HP F1044B ac adapter (the type shipped with your OmniBook) or
an HP-approved ac adapter. Using any other adapter could damage the
OmniBook and void your warranty. Always plug it into a grounded outlet. Note
that the adapter plug has negative polarity—the inner contact is negative, and
the outer is positive.
Unplug the ac adapter from the OmniBook before you unplug the power cord.
Otherwise, the OmniBook could stop responding, requiring a reset.
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 small space.
It’s a good idea to use the ac adapter during operations that take more power—for
example, those involving certain external connections, such as using a floppy drive
or serial port.
The charging light turns on while the ac adapter is plugged in.
