S Ystem Beep Codes - Dell 4100 Installation And Troubleshooting Manual

S
ystem Beep Codes
When errors occur during a boot routine that cannot be
reported on the monitor, the computer may emit a series
of beeps that identify the problem. The beep code is a pat-
tern of sounds: for example, one beep, followed by a
second beep, and then a burst of three beeps (code 1-1-3)
means that the computer was unable to read the data in
nonvolatile random-access memory (NVRAM). This
information is valuable to the Dell support staff if you
need to call for technical assistance.

When a beep code is emitted, write it down on a copy of
the Diagnostics Checklist found in Appendix A, and then
look it up in Table 3-2. If you are unable to resolve the
problem by looking up the meaning of the beep code, use
the system diagnostics to identify a more serious cause. If
you are still unable to resolve the problem, see Chap-
ter 11, "Getting Help," for instructions on obtaining
technical assistance.
