Computer 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 “
Getting Help ,” and then look it up in “ Computer Beep
Codes .” 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 problem, see “ Getting Help ” for
instructions on obtaining technical assistance.
