Troubleshooting

Solving Basic Problems

If you need to recover the online User’s Guide

If you have deleted the online User’s Guide but would like to access it, you can restore it from the Recovery CD-ROM.

Run: omnibook\hputil\disk1\setup.exe.

If the OmniBook doesn’t turn on with a fresh battery

If you replaced the battery after the OmniBook turned off due to a low battery, either plug in the ac adapter—or turn off the OmniBook, then hold F4 and press the On/Off key (F4+ON) to turn it on.

If your 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.

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.

If the computer seems slow

Check that Cache is enabled (in the System Configuration Utility, open the System menu and check Enable Cache).

You might need to install more RAM. The memory-expansion boards are HP part numbers F1167A (8 MB), F1168A (16 MB), and F1169A (32 MB).

If you cannot install Windows NT 3.51

In the System Configuration Utility, under the System menu, Boot Devices, enable the checkbox Force PCI Bridge Configuration.
