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 Diagnostics Checklist found in "

Getting Help

," and then look it up in Table 2. 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.
