If you replaced the battery after the OmniBook turned off due to a low battery,
either plug in the ac adapter or press F4+ON to turn on the OmniBook.

If the new battery pack is low, plug in the ac adapter.

If the OmniBook doesn’t suspend immediately

If the OmniBook is performing an operation, it normally waits for the operation to
finish.

If you’re using MS-DOS Prompt in the full screen (not inside a window), it may
take up to 10 to 15 seconds to suspend.

If the OmniBook reboots every time you turn it on

This is normal if you turn it off by pressing CTRL+ALT+On/Off.

Advanced power management (APM) may be disabled. Check your power
management settings using the

System Configuration Utility.

If the battery pack doesn’t charge or stops charging

Check that the battery is fully installed and locked in place.

Turn off the OmniBook, then check that the battery contacts are clean and that
the ac adapter cables are fully plugged in.

Move the OmniBook away from any nearby heat source. Unplug the ac adapter
and allow the battery to cool down. An elevated battery temperature prevents
charging.

A battery that is completely discharged can require several hours to recover and
start charging.

If your OmniBook password doesn’t work

Check whether Num Lock is off. Try changing it.

If you’ve forgotten your password, have your OmniBook at hand and call
Hewlett-Packard at the phone number in the Support and Service booklet or in
OmniBook Support in the online OmniBook Library.

If a boot ROM on a PCI card doesn’t work

You cannot use boot ROMs to boot off the server with a PCI network adapter.
(You can do so with an ISA adapter.)

Lockup Problems

If you have problems that interfere with turning on or starting the OmniBook, see the
troubleshooting chapter in the OmniBook Installation and Setup Guide, which came
with the OmniBook.

If the OmniBook beeps repeatedly

If two beeps occur every 10 seconds or so, battery power is critically low and
less than 2 minutes of operation remain. Plug in the ac adapter, or turn off the
OmniBook and insert a fresh battery—see

“To replace the battery.”

If an application stops responding
