When to Use the Dell Diagnostics
If you experience a problem with your computer, run the Dell Diagnostics before you call Dell for technical assistance. The Dell Diagnostics tests
check your computer's hardware without additional equipment and without the risk of destroying data. When the diagnostics tests complete without
indicating any problems, you can have confidence in your computer's operation. If the tests indicate a problem you cannot solve by yourself, the test
results provide important information you will need when talking to Dell's service and support personnel.
NOTICE: Only use the Dell Diagnostics to test your Dell computer. Using this program with other computers may cause incorrect
computer responses or result in error messages.
