his chapter describes beep codes and system error messages that can occur
during the POST or, in the case of some failures, during normal computer oper-
ation. 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, you should use the Dell Diagnostics to run the appropriate
tests to help isolate the source of the problem. See “Running the Dell Diagnos-
tics” in Chapter 2.

OST Beep Codes
If the monitor 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. Table 3-1 lists the beep codes that may be
generated during the POST. Most beep codes indicate a fatal error that prevents
the computer from completing the boot routine until the indicated condition is
corrected.
When the computer emits a beep code, record the code and then find it in
Table 3-1. If the table does not lead to the source of the problem, run the appro-
priate tests in the Dell Diagnostics to assist in troubleshooting the problem.
