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" on page 286.
2 Run the Dell Diagnostics to identify a more serious cause (see "Dell
Diagnostics" on page 123).
3 Contact Dell for technical assistance (see "Contacting Dell" on page 287).
