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.
2
See "Dell Diagnostics" on page 21 to identify a more serious cause.
