Beep Codes

Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. For example, beep code 1-3-1 consists of one beep, a burst of three beeps, and then one beep.This beep code tells you that the computer encountered a memory problem.

Reseating the memory modules (see Installing Memory) may fix the beep code errors in the following table. If the problem persists, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance.

Code	Cause
1-3-1 through 2-4-4	Memory not being properly identified or used
4-3-1	Memory failure above address 0FFFFh

The following table lists beep codes for non memory related errors.

Code	Cause
1-1-2	Microprocessor register failure
1-1-3	NVRAM
1-1-4	ROM BIOS checksum failure
1-2-1	Programmable interval timer
1-2-2	DMA initialization failure
1-2-3	DMA page register read/write failure
3-1-1	Slave DMA register failure
