When errors occur during the boot routine that cannot be reported on the built-in dis-

play or on an external monitor (if attached), the 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 important 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 Chapter 5, and then look it up in Table 3-3. 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. (See Chapter 4, “Running the Dell Diagnostics.”) If you

are still unable to resolve the problem, call Dell for technical assistance. (See

Chapter 5, “Getting Help,” for instructions.)
