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. For example, beep code 1-3-1 (one possible beep code) 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 correct the following beep code errors. If the problem persists, see "Contacting Dell" in your Owner's Manual for
instructions on obtaining technical assistance.
