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 a beep code is emitted, write it down and look it up in the following table.
