Beep Codes and Error Messages
T
his chapter describes beep codes and system error messages that can occur
during computer start-up or, in the case of some failures, during normal com-
puter operation. The tables in this chapter list faults that can cause a beep code
or system error message to occur and the probable causes of the fault in each
case.
If a faulty computer does not emit beep codes or display system error messages
to indicate a failure, use the Dell diagnostics to help isolate the source of the
problem. See “Running the Dell Diagnostics” found later in this chapter.

If the display cannot display error messages during the POST, the computer
may emit a series of beeps that identifies the problem or that can help you iden-
tify a faulty component or assembly. The following table lists the beep codes
that may be generated during POST. Most beep codes indicate a fatal error that
requires replacement of the system board or other corrective actions before the
computer can operate.
