Problem Description
Memory modules are detected,
but a memory configuration or
compatibility error exists.
A failure has occurred.
This pattern also displays when
you enter system setup and
may not indicate a problem
(see "System Setup" on
page 79).
After POST is complete, all
four diagnostic lights turn
green briefly before turning off
to indicate normal operating
condition.
Suggested Resolution
• Ensure that no special
memory module/memory
connector placement
requirements exist (see
"Memory" on page 155).
• Verify that the memory
modules that you are
installing are compatible
with your computer (see
"Memory" on page 155).
• If the problem persists, (see
"Contacting Dell" on
page 267).
• Ensure that the cables are
properly connected to the
system board from the hard
drive and the optical drive.
• Check the computer
message that appears on
your monitor screen.
• If the problem persists, (see
"Contacting Dell" on
page 267).
