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.
