Solving Problems
Beep Codes
Your computer might emit a series of beeps
during start-up if there are errors or problems.
This series of beeps, called a beep code,
identifies a problem. If this occurs, write
down the beep code and contact Dell (see
“Contacting Dell” on page 77).
NOTE: To replace parts, see the Service
Manual at support.dell.com/manuals.
