Troubleshooting Tools

When to Use the Dell Diagnostics

If you experience a problem with your computer, perform the checks in 
Lockups and Software Problems (see "Troubleshooting" on page 113) and run 
the Dell Diagnostics before you contact Dell for assistance.

You can run the Dell Diagnostics from your hard drive or from the 

Drivers and 

Utilities disc.
See "System Setup" on page 81 to review your computer’s configuration 
information, and ensure that the device that you want to test displays in 
System Setup and is active.

 

NOTE: 

The Dell Diagnostics works only on Dell computers.

 

NOTE: 

Print the following procedures before you run the Dell diagnostics.

Starting the Dell Diagnostics From Your Hard Drive

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

NOTE: 

If your computer cannot display a screen image, see 

page 269.

1 Turn on (or restart) your computer.
2 When the DELL logo appears, press <F12> immediately.

 

NOTE: 

Keyboard failure may result when a key is held down for extended 

periods of time. To avoid possible keyboard failure, press and release <F12> in 
even intervals to open the 

Boot Device Menu.

 

NOTE: 

If at any time a message appears stating that no diagnostics utility 

partition has been found, run the Dell Diagnostics from your Drivers and 
Utilities disc 

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

your computer and try again.
