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.
Reseating the memory modules
may fix the beep code errors in the following table. If the problem persists, see "Contacting Dell" in your
Owner's Manual
for
instructions on obtaining technical assistance.
If you hear one of the following beep codes, see "Contacting Dell" in your
Owner's Manual
for instructions on obtaining technical assistance.

A possible expansion card failure has
occurred.
1.
Determine if a conflict exists by

computer.
2.
If the problem persists,
reinstall the card
that you removed, remove a different card, and
then restart the computer.
3.
Repeat this process for each card. If the computer starts normally, troubleshoot the last
card removed from the computer for resource conflicts (see "Resolving Software and
Hardware Incompatibilities" in your
Owner's Manual
).
