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 consists of repetitive three short
beeps. This beep code tells you that the computer encountered a possible
system board failure.
If your computer beeps during start-up:
1
Write down the beep code.
2
Run the Dell Diagnostics to identify a more serious cause (see "Dell
Diagnostics" on page 31).
