Copyright IBM Corp. 1996 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 self-tests and system programs contained in Easy-Setup. 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.
