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.) Problems during Reboot 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” . Problems during Reboot 88
