Dell Diagnostics
When to Use the Dell Diagnostics
If you experience a problem with your computer, perform the checks in "Solving Problems" in
your User's Guide and run the Dell Diagnostics before you contact Dell for technical
assistance. Running the Dell Diagnostics may help you resolve the problem without
contacting Dell. If you do contact Dell, the test results can provide important information for
Dell's service and support personnel.
The Dell Diagnostics allows you to:
• Perform tests on one or all devices.
• Select tests based on a symptom of the problem you are having.
• Choose how many times a test is run.
• Suspend testing if an error is detected.
• Access help information that describes the tests and devices.
• Receive status messages that tell you whether tests completed successfully.
• Receive error messages if problems are detected.
Starting the Dell Diagnostics
It is recommended that you print these procedures before you begin.
