The Dell Diagnostics is located on a hidden diagnostic utility partition on your hard drive.

NOTE: If your computer cannot display a screen image, contact Dell (see "Contacting Dell" in your online User’s Guide).

1Shut down the computer.

2If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.

4Diagnostics can be invoked one of two ways:

•Turn on the computer. 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.

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

NOTE: If you see a message stating that no diagnostics utility partition has been found, run the Dell Diagnostics from the optional Drivers and Utilities CD.

The computer runs the Pre-boot System Assessment, a series of initial tests of your system board, keyboard, hard drive, and display.

•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 <Esc>; 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 (see "Contacting Dell" in the online User’s Guide for your computer).

If the Pre-boot System Assessment completes successfully, you receive the message Booting Dell Diagnostic Utility Partition. Press any key to continue.
