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.

2.Run the Dell Diagnostics to identify a more serious cause.

3.Contact Dell for technical assistance (see your computer Owner's Manual for information about how to contact Dell).
