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

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.
