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.
2. Run the Dell Diagnostics (see Dell Diagnostics) to identify a more serious cause.
3. Contact Dell (see Contacting Dell) for technical assistance.
