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 listed 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 beep codes listed in the following table, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance.
