Overview

If you experience a problem with your computer, run the Dell Diagnostics before you call Dell for technical assistance. The diagnostics tests check your computer's hardware without additional equipment and without the risk of destroying data. When the diagnostics tests complete without  indicating problems, you can have confidence in your computer's operation. If the tests indicate a problem you cannot solve, the test error messages provide important information you need when talking to Dell's service and support personnel.

NOTICE: Only use the Dell Diagnostics to test your Dell computer system. Using this program with other computers may cause incorrect computer responses or result in error messages.

Features

The diagnostic test group features allow you to take the following actions:

• Perform quick checks or extensive tests on one or all devices

• Choose the number of times a test group or subtest is repeated

• Display or print test results or save them in a file

• Suspend testing if an error is detected or terminate testing when an adjustable error limit is reached

• Access online Help screens that describe the tests and tell how to run them

• Read status messages that inform you whether test groups or subtests completed successfully

• Receive error messages that appear if problems are detected
