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 on the "Diagnostics Checklist" in your

User’s Guide

.

2

Run the Dell Diagnostics to identify a more serious cause.

3

Contact Dell for technical assistance.
