When to Use the Dell Diagnostics

Whenever a major component or device in the computer does not function properly, the component or
device may have failed. As long as the microprocessor and input/output (I/O) components of the computer
(the display, keyboard, and diskette drive) are working, use the Dell Diagnostics. If you are experienced with
computers and know which component(s) you need to test, select the appropriate diagnostic test group(s) or
subtest(s). If you are unsure about how to begin diagnosing a problem, read the rest of this chapter.

Before You Start Testing

Follow these steps to safeguard your master copy of the Dell Diagnostics Diskette:

1. Make a working copy of the Dell Diagnostics Diskette on a blank diskette.

Refer to your operating system's documentation for information on how to duplicate diskettes. Put the
original diskette away for safekeeping.

2. Turn on your printer, if one is attached, and make sure it is online.
3. Confirm the computer's system configuration information and enable all of its components and devices,

such as ports.

For instructions, see

Using the System Setup Program

.

4. Disable all system setup options for power management.

5. Attach an AC adapter to the computer.

Although it is possible to run the Dell Diagnostics on a computer using battery power, connecting the
computer to AC power helps ensure that power will not be lost during the tests.
