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" in your User’s Guide.
2 Run the Dell Diagnostics to identify a more serious cause.
