PROBLEM
Diskette Drive Errors
A diskette won't load.
A Non-System Disk or
Disk Error message is
displayed.
CD-ROM Problems
CD-ROM disc cartridge does not
eject due to a power failure or
software error.
Monitor Problems
The monitor screen
remains dark.
Troubleshooting
CORRECTIVE ACTION
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.
If you are starting from the diskette drive,
insert a diskette with system files into drive
A. If a 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.
Power off the system. See the emergency
eject screw in Chapter 1.
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.
Press a key on the keyboard or move the
mouse to make sure the system is not in
suspend mode.
Check that the system unit and monitor power
lamps are on, all monitor connections are
tight, and the brightness and contrast controls
are adjusted.
