Diagnostic Lights
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the
Product Information Guide.
To help troubleshoot a problem, your computer has four lights labeled 1, 2, 3, and 4 on the front panel (see Front View
). When
the computer starts normally, the lights flash before turning off. If the computer malfunctions, the sequence of the lights help
to identify the problem.
NOTE: After the computer completes POST, all four lights turn off before booting to the operating system.

Suggested Resolution
The computer is in a
normal off condition
or a possible pre-
BIOS failure has
occurred.
The diagnostic lights
are not lit after the
system successfully
boots to the
operating system.
Plug the computer into a working electrical outlet (see "Power Problems" in
your Owner's Manual).
If the problem persists, contact Dell (see "Contacting Dell" in your Owner's
Manual).

additional memory modules (one at a time) until you have identified a

drive or hard drive
failure has occurred.

additional memory modules (one at a time) until you have identified a
faulty module or reinstalled all modules without error.
