Chapter 8. Solving Computer Problems
Computer problems can be caused by software, hardware, or both.
You can diagnose and solve many problems with the assistance of
the built-in self-tests. If a hardware problem is detected by the selftests, an error message is displayed.
You can then identify the problem for the service representative.
Make a note of all error codes and give them to the service
representative when you call for service. Troubleshooting charts an
other information will help you determine what corrective action to
take.
Important
Use this chapter to test and diagnose only IBM products. Using the
charts on 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.
