System Beep Codes
When errors occur during a boot routine that cannot be reported on the monitor, your computer may emit a beep code that identifies 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
and look it up in the following table. If you are unable to resolve the
problem by looking up the meaning of the beep code, use the
Dell Diagnostics
