If you experience a problem with your computer, perform the checks in the "Solving Problems" section in your User's Guide or Owner's Manual 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
NOTICE: Use the Dell Diagnostics to test your Dell computer only. Using this program with other computers can result in error messages.
