Features of the System Diagnostics
When to Use the System Diagnostics
Unlike many diagnostic programs, the system diagnostics helps you check the system's hardware without any additional
equipment and without destroying any data. By using the system diagnostics, you can have confidence in the system's
operation. If you find a problem that you cannot solve by yourself, the diagnostic tests can provide you with important
information you will need when talking to a technical assistance representative.
NOTICE:
Use the system diagnostics to test only Dell systems. If you use this program with other systems, incorrect
system responses or error messages may result.
NOTE:
To use system diagnostics, connect a keyboard, monitor, and mouse to the system or use the console
redirection function on the serial port (COM1). See
for the serial port location. See your User's Guide for
more information on console redirection.
Features of the System Diagnostics
The system diagnostics provides a series of menus and options from which you choose particular device groups or devices.
You can also control the sequence in which the tests are run. The diagnostic menus also have these helpful features:
Options that let you run tests individually or collectively
An option that allows you to choose the number of times a test is repeated
The ability to display or print test results or to save them in a file
Options to temporarily suspend testing if an error is detected or to terminate testing when an adjustable error limit is
reached
Help messages that briefly describe each test and its parameters
Status messages that inform you whether device group or device tests are completed successfully
Error messages that appear if any problems are detected
When to Use the System Diagnostics
Whenever a major component or device in the system does not function properly, you may have a component failure. As long
as the microprocessor and the input and output components of the system (the monitor, keyboard, and diskette drive) are
working, you can use system diagnostics. If you know what component(s) you need to test, select the appropriate diagnostic
device group(s) or subtest(s). If you are unsure about the scope of the problem, read the remainder of the information in this
section.
