When to Use the Dell Diagnostics
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:
l Perform tests on one or all devices.
l Select tests based on a symptom of the problem you are having.
l Choose how many times a test is run.
l Suspend testing if an error is detected.
l Access help information that describes the tests and devices.
l Receive status messages that tell you whether tests completed successfully.
l Receive error messages if problems are detected.
Starting the Dell Diagnostics
It is recommended that you print these procedures before you begin.
The Dell Diagnostics is located on a hidden diagnostic utility partition on your hard drive.
1. Shut down the computer.
2. If the computer is connected to a media base (docked), undock it. See the documentation that came with your media base for instructions.
3. Connect the computer to an electrical outlet.
4. Turn on the computer. When the DELL™ logo appears, press <F12>immediately.
If you wait too long and the Microsoft® Windows® logo appears, continue to wait until you see the Windows desktop. Then shut down your computer
through the Start menu and try again.
5. When the boot device list appears, highlight Diagnostics and press <Enter>.
The computer runs the Pre-boot System Assessment, a series of initial tests of your system board, keyboard, hard drive, and display.
l During the assessment, answer any questions that appear.
NOTICE: Use the Dell Diagnostics to test your Dell™ computer only. Using this program with other computers can result in error messages.
NOTE: If your computer cannot display a screen image, contact Dell.
NOTE: If you cannot see anything on your display, hold down the mute button and press the computer's power button to begin the Dell Diagnostics.
The computer automatically runs the Pre-boot System Assessment.
