Troubleshooting
PROBLEM
CORRECTIVE ACTION
Diskette Drive Errors
A diskette won’t load.
Check that the diskette is inserted correctly.
Verify that the system unit and monitor
power lamps are on and that the power-on
screen appears on the screen.
If the diskette is not formatted, format it. See
your MS-DOS documentation.
If the diskette drive busy lamp does not light
when you load the diskette, try a different
diskette. If this loads, the problem is in the
software. Call your software dealer.
A Non-System Disk or
Disk Error message is
displayed.
If you are starting from the diskette drive,
insert a diskette with system files into
drive A. If bootable diskette does not boot,
use Setup to verify that the initial boot
parameter is set to diskette drive A and
not a hard disk.
Monitor Problems
The monitor screen
remains dark.
Check that the monitor power cable is
connected to the monitor and a power
outlet.
Be sure that the monitor signal cable is
connected to the system unit.
Check that the system unit and monitor
power lamps are on, all monitor connections
are tight, and the brightness and contrast
controls are adjusted.
Press the space bar, or move the mouse
to wake the system out of a power
management mode (if set).
A distorted image appears
on your monitor screen.
Adjust the video controls on your monitor.
If this doesn't help, turn the monitor off for
a few seconds, then turn it back on.
