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
• Press CTRL+ALT+DEL, then stop the application.
• Reboot the OmniBook.
If a screen saver causes lockup
• If you’ve previously set up an OmniBook password, you should delete the
OmniBook password. Screen savers conflict with password protection, and
together they can lock up the OmniBook.
If you can’t start Windows
• In the System Configuration Utility , set Factory Default Settings in the Defaults
menu.
