Dell 7500 manual System Beep Codes, Run the PC-AT Compatible Keyboards device group

System Beep Codes

When errors occur during the boot routine that cannot be reported on the integrated display 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 burst of three beeps, followed by a single beep, and then another burst of three beeps (code 1-3-1-3) means that the computer was unable to read data from the keyboard. 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, “Getting Help,” and then look it up in Table C-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. (See “Running the Dell Diagnostics” found later in this chapter) If you are still unable to resolve the problem, call Dell for technical assistance. (See Chapter 5, “Getting Help,” for instructions.)
