If the computer is connected to a docking device (docked), undock it. See the documentation that

came with your docking device for instructions. Ensure the computer is connected to a known good

electrical outlet.

Turn on (or restart) your computer.

Diagnostics can be invoked one of two ways:

• When the DELL™ logo appears, press <F12> immediately. Select Diagnostics from the boot

menu and press <Enter>.

NOTE: If you wait too long and the operating system logo appears, continue to wait until you see the

Microsoft® Windows® desktop; then, shut down your computer and try again.

NOTE: Before attempting option B, the computer must be powered down completely.

• Press and hold the <Fn> key while powering the computer on.

NOTE: If you see a message stating that no diagnostics utility partition has been found, run the Dell

Diagnostics from the Drivers and Utilities media.

The computer runs the Pre-boot System Assessment, a series of initial tests of your system board,

keyboard, display, memory, hard drive, etc.

• During the assessment, answer any questions that appear.

• If a failure is detected, the computer stops and beeps. To stop the assessment and restart the

computer, press <N>; to continue to the next test, press <Y>; to retest the component that

failed, press <R>.

• If failures are detected during the Pre-boot System Assessment, write down the error code(s) and

contact Dell.

If the Pre-boot System Assessment completes successfully, you will receive the following message:

Booting Dell Diagnostic Utility Partition. Press any key to continue.

Press any key to start the Dell Diagnostics from the diagnostics utility partition on your harddrive.
