When to Use the Dell Diagnostics
Whenever a major component or device in your computer does not function properly, you may have a
component failure. If you are experiencing a problem with your computer, Dell recommends that you
perform the checks in "
Solving Problems " and run the Dell Diagnostics before you call Dell for technical
assistance. Running the Dell Diagnostics may help you to resolve the problem yourself quickly without
having to contact Dell for assistance.
If you are experienced with computers and know what component(s) you need to test, simply select the
appropriate diagnostic test group(s) or subtest(s). If you are unsure about how to begin diagnosing a
problem, see "
Starting the Dell Diagnostics " and " Advanced Testing ."
Features of the Dell Diagnostics
The Dell Diagnostics helps you check your computer's hardware without any additional equipment and
without destroying any data. By using the diagnostics, you can have confidence in your computer's
operation. And if you find a problem you cannot solve by yourself, the diagnostic tests can provide you with
important information you will need when talking to Dell's service and support personnel. If you are
experiencing a problem with your computer, Dell recommends that you perform the checks in "
Solving
Problems " and run the Dell Diagnostics before you call Dell for technical assistance.
