Diagnostic Lights



To help you troubleshoot a problem, your computer has four lights labeled "A," "B," "C," and "D" on the back panel. The lights can be yellow or green. When

the computer starts normally, the lights flash. After the computer starts, all four lights display solid green. If the computer malfunctions, the color and

sequence of the lights identify the problem.



CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in your Owner's Manual or Product Information

Guide.

Light Pattern

Problem Description

Suggested Resolution



The computer is in a normal

off condition or a possible

pre-BIOS failure has

occurred.

Verify that the computer is plugged into a working electrical outlet and that you have pressed the power

button.



Memory modules are

detected, but a memory

failure has occurred.

lIf you have one memory module installed, reinstall it and restart the computer.

lIf you have two or more memory modules installed, remove the modules, reinstall one module, and

then restart the computer. If the computer starts normally, reinstall an additional module. Continue

until you have identified a faulty module or reinstalled all modules without error.

lIf available, install properly working memory of the same type into your computer.

lIf the problem persists, see "Contacting Dell" in your Owner's Manual.

A possible expansion card

failure has occurred.

1. Determine if a conflict exists by removing a card (not the video card) and then restarting the

computer.

2. If the problem persists, reinstall the card that you removed, remove a different card, and then

restart the computer.

3. Repeat this process for each card. If the computer starts normally, troubleshoot the last card

removed from the computer for resource conflicts (see "Resolving Software and Hardware

Incompatibilities" in your Owner's Manual).

4. If the problem persists, see "Contacting Dell" in your Owner's Manual.



A possible floppy or hard

drive failure has occurred.

Reseat all power and data cables and restart the computer.



A possible USB failure has

occurred.

Reinstall all USB devices, check cable connections, and then restart the computer.



No memory modules are

detected.

lReinstall all memory modules and restart the computer.

lTo eliminate the possibility of a faulty memory connector, remove all memory modules, reinstall one

memory module (if the computer supports a single module), and then restart the computer. If the

computer starts normally, move the memory module to a different connector and restart the

computer. Continue until you have identified a faulty connector or reinstalled all modules without

error.



Memory modules are

detected, but a memory

configuration or compatibility

error exists.

lEnsure that no special memory module/memory connector placement requirements exist.

lVerify that the memory modules that you are installing are compatible with your computer.

lIf the problem persists, see "Contacting Dell" in your Owner's Manual.



Another failure has occurred.

lEnsure that the cables are properly connected to the system board from the hard drive, CD drive,

and DVD drive.



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. One possible beep code (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 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. 



If you hear one of the following beep codes, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance.



lIf the problem persists, see "Contacting Dell" in your Owner's Manual.



The computer is in a normal

operating condition after

POST.

None.

Recommended Tools

Precautionary Measures

Protecting Against Electrostatic Discharge



This section provides procedures for removing and replacing the components. Unless otherwise noted, each procedure assumes that the following conditions

exist:

lYou have performed the steps in "Precautionary Measures."

lYou have read the safety information in your Owner's Manual or Product Information Guide.

lYou have opened the computer cover.



Recommended Tools



Your computer is primarily a tool-less one, but certain procedures (such as removing the heat-sink blower or the control panel) require the use of one or more

of the following tools:

lSmall flat-blade screwdriver

l#1 and #2 Phillips-head screwdriver

lAn 8-inch, #2 Phillips-head screwdriver



Precautionary Measures



Use the following safety guidelines to help protect your computer from potential damage and to ensure your own personal safety.



Before you start to work on the computer, perform the following steps in the sequence listed:

1. Shut down the computer through the Start menu.

2. Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut

down your computer, turn them off now.



3. Disconnect any telephone or telecommunication lines from the computer.

4. Disconnect your computer and all attached devices from electrical outlets, and then press the power button to ground the system board.



In addition, take note of these safety guidelines when appropriate:

lWhen you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if

you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in your Owner's Manual or Product Information

Guide.

CAUTION: Donotattempttoservicethecomputeryourself,exceptasexplainedinyouronlineDell™documentationorininstructionsotherwise

provided to you by Dell. Always follow installation and service instructions closely.

NOTICE: To help avoid possible damage to the system board, wait 5 seconds (or wait until the standby light is extinguished) after turning off the

computer and unplugging the power cable before removing a component from the system board or disconnecting a device from the computer.

NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.

NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the

computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.

aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.

lHandle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket.

Hold a component such as a microprocessor chip by its edges, not by its pins.



Protecting Against Electrostatic Discharge



Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch

any of your computer's electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis.



As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated.



You can also take the following steps to prevent damage from electrostatic discharge (ESD):

lWhen unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are

ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.

lWhen transporting a sensitive component, first place it in an antistatic container or packaging.

lHandle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
