APPENDIX B - TROUBLESHOOTING
The screen seems to be constantly wavering.
1. If the monitor is close to another montiro, the adjacent monitor may
need to be turned off. Fluorescent lights adjacent to the montior may
also cause screen wavering.
Power Supply
When the computer is turned on, nothing happens.
1. Check that one end of the AC power cord is plugged into a live outlet
and the other end properly plugged into the back of the system.
2. Make sure that the voltage selection switch on the back panel is set
for the correct type of voltage you are using.
3. The power cord may have a “short” or “open”. Inspect the cord and
install a new one if necessary.
Floppy Drive
The computer cannot access the floppy drive.
1. The floppy diskette may not be formatted. Format the diskette and try
again.
2. The diskette may be write-protected. Use a diskette that is not write-
protected.
3. You may be writing to the wrong drive. Check the path statement to
make sure you are writing to the targeted drive.
4. There is not enough space left on the diskette. Use another diskette
with adequate storage space.
Hard Drive
Hard disk failure: Make sure the correct drive type for the hard disk drive has
been entered in the BIOS.
E xcessively long formatting period: If your hard drive takes an excessively
long period of time to format, it is likely a cable connection problem. However,
if your hard drive has a large capacity, it will take a longer time to format.
Parallel Port
The parallel printer doesn’t respond when you try to print.
1. Make sure that your printer is turned on and that the printer is on-line.
2. Make sure your software is configured for the right type of printer
attached.
