Beep Codes
Your computer might emit a series of beeps during start-up if the monitor cannot display errors or
problems. This series of beeps, called a beep code, identifies a problem. One possible beep code (code
1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the
computer encountered a memory problem.
If your computer beeps during start-up:
1
Write down the beep code on the
Diagnostics Checklist
.
2
Run the
Dell Diagnostics
to identify a more serious cause.
No memory modules are detected.
• If you have one memory module installed,
reinstall it and restart the computer. (see
"Memory" for instructions on how to
remove and install memory modules.)
• If you have two or more memory modules
installed, remove the modules, reinstall
one module, and then restart the
computer. If the computer starts normally,
reinstall an additional module. Continue
until you have identified a faulty module
or reinstalled all modules without error.
• If available, install properly working
memory of the same type into your
computer.
• If the problem persists, contact Dell.
Memory modules are detected, but a
memory configuration or compatibility
error exists.
• Ensure that no special memory
module/memory connector placement
requirements exist.
• Verify that the memory modules that you
are installing are compatible with your
computer.
• If the problem persists, contact Dell.
A failure has occurred.
This pattern also displays when you
enter
system setup
and may not indicate a
problem.
• Ensure that the cables are properly
connected to the system board from the
hard drive, CD drive, and DVD drive.
• Check the computer message that appears
on your monitor screen.
• If the problem persists, contact Dell.
After POST is complete, all four diagnostic
lights turn green briefly before turning off
to indicate normal operating condition.
None.
