Troubleshooting

This section discusses problems caused by your computer’s hardware or 
attached peripherals. Basic problems may occur in the following areas:

When the computer does not start properly, check the following items:

■

Self Test

■

Power Sources

■

Power-on Password 

The problems may be caused by your software or 
diskette. If you cannot load a software package, the 
media (usually a diskette) may be damaged or the 
program might be corrupted. Try loading another copy 
of the software.

If an error message appears while you are using a 
software package, check the software documentation. 
These documents usually include a problem solving 
section or a summary of error messages.

Next, check any error messages in the OS 
documentation.

If you cannot find a software problem, check your 
hardware. First run through the items in the preliminary 
checklist above. If you still cannot correct the problem, 
try to identify the source. The next section provides 
checklists for individual components and peripherals.
