Starting the Dell Diagnostics
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 the
User's Guide
for
contact information.
1. Shut down the computer.
2. If the computer is connected to a docking device (docked), undock it. See the documentation
that came with your docking device for instructions.
3. Connect the computer to an electrical outlet.
NOTE:
If you do not see anything on your display, hold down the mute button and press the
power button (instead of <F12>) to begin the Dell Diagnostics. You do not need to highlight
Diagnostics
and press <Enter>. The computer automatically runs the Pre-boot System
Assessment.
4. Turn on the computer. When the DELL™ logo appears, press <F12> immediately. If you wait
too long and the Microsoft® Windows® logo appears, continue to wait until you see the
Windows desktop. Then shut down your computer and try again.
5. When the boot device list appears, highlight
Diagnostics
and press <Enter>.
The computer begins to run the Pre-boot System Assessment, a series of embedded diagnostics
that perform initial testing on your system board, keyboard, hard drive, and display.
●
During the assessment, answer any questions that appear.
●
If a component failure is detected, the computer stops and beeps. To stop the
assessment and reboot to the operating system, press <N>; 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 before continuing on to the Dell Diagnostics. See the
