ticular test groups or subtests. You can also control the sequence in which the tests
are run. The program also has these helpful features:

An option that sets the number of times a test group or subtest runs
Options to temporarily suspend testing if an error is detected or to end testing
when an adjustable error limit is reached
Status messages that inform you of test group and subtest progress
Error messages that appear if any problems are detected
The ability to display or print test results or to save the results in a file

Use the Dell Diagnostics after you install an upgrade and whenever a major compo-
nent or device in your computer system does not function properly. As long as the
microprocessor and the input and output components of your computer system (the
monitor, keyboard, and diskette drive) are working, you can run the Dell Diagnostics. If
you are experienced with computers and know what component(s) to test, select the
appropriate test group(s) or subtest(s). If you are unsure about how to begin diagnos-
ing a problem, read the rest of this chapter.
