System 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
problem by looking up the meaning of the beep code, use the
problem, see "Getting Help" for instructions on obtaining technical assistance.
