Troubleshooting
The Dell Diagnostics is located on a separate diagnostic utility partition on
your hard drive.
NOTE:
If your computer does not display a screen image, contact Dell (see
"Contacting Dell" on page 137.
1 Ensure that the computer is connected to an electrical outlet that is
known to be working properly.
2 Turn on (or restart) your computer.
3 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.
If you wait too long and the operating system logo appears, continue to
wait until you see the Microsoft Windows desktop, and then shut down
your computer and try again.
4 Use the up- and down-arrow keys to select Diagnostics from the boot
menu and then press <Enter>.
NOTE:
If you see a message stating that no diagnostics utility partition has
been found, run the Dell Diagnostics from your Drivers and Utilities disc (see
"Starting the Dell Diagnostics From the Drivers and Utilities Disc" on page 15).
5 Press any key to start the Dell Diagnostics from the diagnostics utility
partition on your hard drive.
6 Press <Tab> to select Test System and then press <Enter>.
NOTE:
It is recommended that you select Test System to run a complete test
on your computer. Selecting Test Memory initiates the extended memory test,
which can take up to thirty minutes or more to complete. When the test
completes, record the test results and then press any key to return to the
previous menu.
7 At the Dell Diagnostics Main Menu, left-click with the mouse, or press
<Tab> and then <Enter>, to select the test you want to run (see "Dell
Diagnostics Main Menu" on page 16).
NOTE:
Write down any error codes and problem descriptions exactly as they
appear and follow the instructions on the screen.
8 After all tests have completed, close the test window to return to the Dell
Diagnostics Main Menu.
