8.Inspect the exterior of the computer, including all controls, indicators, and user-accessible data storage devices for any signs of physical damage.

Does the inspection reveal any problems?

Yes. Refer to the appropriate procedure in Chapter 4, “Removing and Replacing Parts.”

No. Proceed to the next section, “Observing the Boot Routine.”

Observing the Boot Routine

After you have performed an external visual inspection as described in the pre- vious procedure, 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 func- tions 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 a copy of the Dell Diagnostics Diskette into drive A. Turn on all peripherals and the computer. If the computer is already on, press the reset button or <Ctrl><Alt><Del> to reboot the system.

NOTE: If the computer is already on, save and close all open files and application programs (if possible) to avoid losing any data. Then perform an orderly shutdown of the operating system (see the operating system doc- umentation for instructions) before rebooting 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.Watch the Num Lock, Caps Lock, and Scroll Lock indicators on the upper-right corner of the keyboard. After all three indicators flash momentarily, the Num Lock indicator should light up and remain on.

Do these indicators flash on and off within approximately 10 seconds after the boot routine starts?

Yes. Proceed to step 4.

No. Troubleshoot the system power supply. If the troubleshooting procedure indicates that the system power supply is operational, troubleshoot the memory.
