To Recharge The Battery Or Run On Ac Power - HP OmniBook 800 User Manual

If you work with an application that uses the serial port, modem port, or
a PC card, exit the application when you're done using it.
If you have a PC card with an external connection, such as a modem or
network card, remove it when you're not using it. Some cards use
significant power, even while they're inactive.
Add system RAM (a memory-expansion board) if you have an 8 MB
system.

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 the ac adapter shipped with the OmniBook (HP part number
F1044B or other Hewlett-Packard adapter intended for use with the
OmniBook 800). 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, which is different from many other
adapters.
You use the ac adapter to recharge the battery pack in the OmniBook. You
can also use it to avoid draining the battery—so it will be at full capacity
when you're away from your desk. (You can even use the ac adapter while
the battery is removed.)
It's a good idea to use the ac adapter during operations that take more
power—for example, those involving external connections, such as using a
floppy drive or serial port. .
