• Make sure you don’t have an external mouse connected. If you do, you can still
return control to the OmniBook mouse by ignoring the external mouse:
In HP User Tools, click Settings, OmniBook External Device.
If the mouse doesn’t work in MS-DOS
• Use the special MS-DOS Mode command. Click Start, Programs, OmniBook,
MS-DOS Mode. This shuts down Windows and loads drivers for MS-DOS. When
you're done, type exit to restart Windows.
If a mouse connected to the serial port doesn’t work properly
• Set up the serial mouse manually. In Control Panel, double-click Add New
Hardware and follow the instructions on the screen. Keep the serial mouse
connected when you restart the OmniBook.
• Check whether the serial mouse is compatible with the OmniBook—the mouse
must be compatible with the 9-pin serial Microsoft Mouse.
