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.

See "Dell Diagnostics" on page 17 to identify a more serious cause.

Quick Reference Guide
Suggested Resolution
• Reinstall all memory modules and restart the computer.
• To eliminate the possibility of a faulty memory connector,
remove all memory modules, reinstall one memory
module (if the computer supports a single module), and
then restart the computer. If the computer starts
normally, move the memory module to a different
connector and restart the computer. Continue until you
have identified a faulty connector or reinstalled all
modules without error.
• Ensure that no special memory module/memory
connector placement requirements exist (see "Memory"
in the online User's Guide for more information).
• Verify that the memory modules that you are installing
are compatible with your computer.
• If the problem persists, contact Dell.
• Ensure that the cables are properly connected to the
system board from all installed hard drives.
• Check the computer message that appears on your
monitor screen.
• If the problem persists, contact Dell.
• None.
