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.
