Observing the Boot Routine After you have performed an external visual inspection as described in the previous section, you should boot the system and, while the boot routine is running, observe the system for any indications of problems. NOTE: Most of the steps in this procedure require observation of system functions and indications, some of which can occur simultaneously. It may be necessary to reboot the system several times in order to complete all of these steps. To observe problem indications during the boot routine, follow these steps: 1. Insert the diagnostics diskette into drive A. Turn on all peripherals and the system unit. If the system unit is already on, press the reset button or to reboot the system. 2. Check the power supply fan. Does the fan run normally? Yes. Proceed to step 3. No. Troubleshoot the system power supply. 3.

If the troubleshooting procedure indicates that the system power supply is operational, troubleshoot the memory. Basic Troubleshooting 2-3
