Troubleshooting Tips
Steady
Amber
Memory modules are
detected, but a
memory power failure
has occurred. • If two or more memory modules are
installed, remove the modules, then
reinstall one module 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 only one
memory module is installed, try
moving it to a different DIMM
connector and restart the computer.
• If available, install verified working
memory of the same type into your
computer.
• If the problem persists, contact Dell
(see "Contacting Dell " on page 66).
Steady
Amber
A possible CPU or
motherboard failure
has occurred. • Replace the CPU with a known good
CPU. If the computer still fails to
boot, inspect the CPU socket for
damage.
• If the problem persists, contact Dell
(see "Contacting Dell " on page 66).
Steady
Amber
BIOS may be corrupt
or missing. • The computer hardware is operating
normally but the BIOS may be corrupt
or missing. Contact Dell (see
"Contacting Dell " on page 66).
Steady
Amber
A possible
motherboard failure
has occurred. • Remove all peripheral cards from the
PCI and PCI-E slots and restart the
computer. If the computer boots, add
the peripheral cards back one by one
until you find the bad one.
• If the problem persists, the
motherboard is probably bad. Contact
Dell (see "Contacting Dell" on
page 66).
