If you experience a problem with your

computer, perform the checks in “Lockups and

Software Problems” on page 39 and run the

Dell Diagnostics before you contact Dell for

technical assistance.
It is recommended that you print these

procedures before you begin.

NOTE: Dell Diagnostics works only on Dell

computers.
NOTE: The

Drivers and Utilities disc

is optional and may not ship with your

computer.

See the Dell Technology Guide to review your

computer’s configuration information, and

ensure that the device that you want to test

appears in the system setup program and is

active.
Start the Dell Diagnostics from your hard drive

or from the

Drivers and Utilities disc.

Starting Dell Diagnostics From Your
Hard Drive

The Dell Diagnostics is located on a hidden

diagnostic utility partition on your hard drive.

a screen image, contact Dell (see

“Contacting Dell” on page 60).

electrical outlet that is known to be working

properly.
