System Beep Codes
When an error that cannot be reported on the monitor occurs during a boot routine, the system 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 system was unable
to read the data in nonvolatile random-access memory (NVRAM). This information is valuable to the Dell
technical support representative if you need to call for technical assistance.
When a beep code is emitted, record it and then look it up in
. If you are unable to resolve the
problem by looking up the meaning of the beep code, use the
to identify a more serious
cause.
