Troubleshooting

Solving Basic Problems

5-6

If the Windows for Workgroups Setup fails due to a problem with the

display driver

• Specify VGA for the display driver.

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 (Nm Lk) 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 (see chapter 1).

If the screen is difficult to read

• Try adjusting the display—press the ∧ and ∨ buttons above the keyboard.

• If the OmniBook is cold, allow it to warm up.

• Set the display resolution to its original setting: 800×600 (SVGA) and 256 colors,

or set the lowest available setting. For Windows for Workgroups, use Display in

OmniBook Tools. For Windows 95, use the Settings tab under Display in the

Control Panel (under HP User Tools or under Settings).

If an external display won't turn on

• If the external display is unrecognized by the OmniBook, the computer will not

send it video signals. However, you can force the computer to send these

signals anyway. Open the OmniBook External Devices screen (Start, Settings,

Control Panel, then OmniBook External Devices). Check the box that reads

“Force video signal to external display”.
