This chapter describes beep codes and system error messages that can occur
during system start-up or, in the case of some failures, during normal system
operation. In some cases, the system may display error messages and emit
beep codes simultaneously. In other cases, such as when a video problem
occurs, the system may emit a beep code even though it cannot display an
error message.
If a faulty system does not emit beep codes or display system error messages
to indicate a failure, run the appropriate tests in the diskette-based diagnostics
to help you isolate the source of the problem. For instructions on starting and
using the diskette-based diagnostics, see “Running the Dell Diagnostics” in
Chapter 2.

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 identify
a faulty component or assembly. Table 3-1 lists the beep codes that may be
generated during POST.
When the system emits a beep code, record the code and then find it in
Table 3-1. If Table 3-1 does not lead to the source of the problem, run the
appropriate tests in the diskette-based diagnostics to assist in troubleshooting
the problem.
