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 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 on a copy of the Diagnostics Checklist in "Getting Help," and then look it up in Table2-4. 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.
