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.

Install a second 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 on the left side 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.

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.
