If the OmniBook reboots every time you turn it on
•
Advanced power management (APM) is probably disabled—in OmniBook Tools
click Power, then select one of the options. If you select Custom, make sure the
Power Management option is enabled.
If the OmniBook beeps instead of turning off
•
If Microsoft at Work Fax is running, exit the program. (Any similar program that
doesn’t allow the OmniBook to suspend operation prevents turnoff.)
If the battery pack doesn’t charge or stops charging
•
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
or turns off the battery.
If your system 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 Service and Support booklet or the OmniBook
Support icon in Program Manager (in the OmniBook Library group).
If the OmniBook doesn’t reboot successfully
•
If no text is displayed during reboot, or if things stop before you see any text about
MS-DOS, the unit probably requires service.
•
If you see error messages during startup, but Windows starts or you get an MS-DOS
prompt, exit Windows. Then type
scandisk to fix problems with drive C. Then
press CTRL+ALT+DEL to reboot—but at the MS-DOS Startup Menu, press F8
ENTER and step through each startup command to find where the problem occurs.
Repair or restore the necessary files as indicated. To restore an original system file,
see
“To recover system files” .
•
If you see text about MS-DOS but things stop before Windows starts or before you
get an MS-DOS prompt, insert the Support Utility disk or other boot disk in the
floppy drive, then press
CTRL+ALT+DEL to reboot from drive A. (If the unit doesn’t
reboot from a floppy boot disk, the unit probably requires service.)
If it reboots, type dir c: to see if drive C contains valid files. Then try the
following:
If drive C has valid files, try typing c:\dos\scandisk (to repair any
defects) and sys a: c: (to restore core MS-DOS files).
Try typing each of these commands to see if it fixes the problem:
fdisk /mbr
(to repair only the boot sector of drive C) and
c:\dos\scandisk (to repair any file defects).
Last resort: The following commands delete all files on drive C, so you must
reinstall your files after running these commands:
fdisk (to reinitialize drive
C), and format c: /u (to prepare drive C for storing data). Reinstall your
files—see
“To reinstall files on drive C” .
