When to Use the Dell Diagnostics

If you experience a problem with your computer, perform the checks in "Lockups and Software Problems" on page 16 and run the Dell Diagnostics before you contact Dell for technical assistance.

It is recommended that you print these procedures before you begin.

NOTICE: The Dell Diagnostics works only on Dell™ computers.

NOTE: The Drivers and Utilities CD is optional and may not ship with your computer.

Start the Dell Diagnostics from either your hard drive or from the Drivers and Utilities CD (also known as the ResourceCD).

Starting the Dell Diagnostics From Your Hard Drive

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 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.

3Connect the computer to an electrical outlet.

4Diagnostics can be invoked one of two ways:

a 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.
