completely and have installed the mouse properly.
Check the port connection (may be loose).
If a serial modem doesn't work properly
In Windows Help use the modem troubleshooter.
Check the port connection (may be loose).
If an I/O card stops communicating properly
It may have been reset if the OmniBook suspended or turned off. Exit and restart
the application.

Check the port connection (may be loose).
Check settings in BIOS Setup.
1. From the Start menu, shut down, then restart the OmniBook.
