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 (one possible beep code)

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 may correct the following beep code errors. If

the problem persists, contact Dell (see "Contacting Dell"

in the

User’s Guide

)

for instructions on obtaining technical assistance.

Another failure has occurred.

• Ensure that all hard drive and

optical drive cables are

properly connected to the

system board (see "System

Board Components" for your

system).

• If there is an error message on

the screen identifying a

problem with a device (such as

the floppy drive or hard drive),

check the device to make sure

it is functioning properly.

• If the operating system is

attempting to boot from a

device (such as the floppy

drive or optical drive), check

system setup (see "System

Setup" in the

User’s Guide

) to

ensure the boot sequence is

correct for the devices

installed on your computer.

• If the problem persists,

contact Dell (see

"Contacting

Dell"

in the

User’s Guide
