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 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 your System's Installation and Troubleshooting Guide, 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 system diagnostics to identify a more serious cause.

Running the System Diagnostics
