Chapter 8. Solving Computer Problems
Computer problems can be caused by software, hardware, or both.
Many problems can be diagnosed and solved with the assistance of
self-tests and system programs. If a hardware problem is detected
by the self-tests, an error message is displayed.
The system programs can identify a problem or provide information
for the service representative. Make a note of all error codes and
give them to the service representative when you call for service. If
the system programs cannot be loaded, the troubleshooting charts
and other information will help you determine what corrective action
to take.
Important
Use this chapter to test only IBM products. Non IBM products
can cause misleading error information or incorrect computer
responses. When testing non IBM products, refer to the
instructions supplied with those products.
