Power Light Problem Description 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 the
User’s
Guide
).
• If the problem persists,
contact Dell (see
"Contacting
Dell"
in the
User’s Guide
).
A possible processor failure has
occurred.
• Reseat the processor (see
Processor information for your
system).
• If the problem persists,
contact Dell (see
"Contacting
Dell" in the User’s Guide
).
Memory modules are detected,
but a memory failure has
occurred.
• If two or more memory
modules are installed, remove
the modules (see "Removing
Memory" in the
User’s Guide
),
then reinstall one module (see
"Installing Memory" in the
User’s Guide
) and restart the
computer. If the computer
starts normally, continue to
install additional memory
modules (one at a time) until
you have identified a faulty
module or reinstalled all
modules without error.
• If available, install working
memory of the same type into
your computer (see "Installing
Memory" in the
User’s Guide
).
• If the problem persists,
contact Dell (see
"Contacting
Dell" in the User’s Guide
).
