Solution
Make sure that the mouse interface cable is securely
connected to the correct system unit receptacle. The
mouse cable fits in the keyboard receptacle, but does not
function properly if you plugged it into the keyboard port by
mistake.
Verify that the correct mouse drivers or software have been
installed.
Turn the mouse over, remove the plastic cover and the
rubber ball, then clean the rubber ball and the metal
contacts inside the mouse. Put the mouse back together
and test it.
Check the system unit fan. If the fan is rotating and the
system is running normally otherwise, the speaker may be
defective. Contact your Unisys Customer Service Engineer
for help.
With the power off, remove all feature boards and
disconnect all internal drives. Turn on the system. If the
problem does not recur, one of the devices you removed
was the cause of the problem. Replace each device one at
a time, testing the system after each device is reconnected.
When the problem recurs, you have found the failed device.
Make sure the floppy disk drive interface cable and power
cable are properly connected.
Verify that all system board jumpers related to the floppy
disk drive are correctly set.
Make sure the cable from the LED to the system board is
properly seated in the system board socket.
Make sure the hard disk drive interface cable and power
cable are properly connected.
Verify that the correct hard drive configuration is stored in
CMOS memory. You can check your configuration by
running the BIOS Setup utility, as described in Section 2.
Turn on the system unit, and determine whether you can
hear the hard disk spinning.
Refer to hard disk installation/troubleshooting instructions.
