S
ystem Beep Codes
When errors occur during a boot routine that cannot be
reported on the monitor, your computer may emit a series
of beeps that identify the problem. The beep code is a
pattern 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 invaluable 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 Chapter 7, “Getting
Help,” and then look it up in Table 2-2. If you are unable
to resolve the problem by looking up the meaning of the
beep code, use the Dell Diagnostics to identify a more
serious cause. If you are still unable to resolve the prob-
lem, see Chapter 7, “Getting Help,” for instructions on
obtaining technical assistance.
