Getting Started

This chapter provides procedures for removing and installing the components in your computer. Unless otherwise noted, each procedure assumes that the following conditions exist:

You have performed the steps in Turning Off Your Computer and Before Working Inside Your Computer.

You have read the safety information in your Dell™ Product Information Guide.

A component can be replaced or—if purchased separately—installed by performing the removal procedure in reverse order.

Recommended Tools

The procedures in this document may require the following tools:

Small flat-blade screwdriver

Phillips screwdriver

Turning Off Your Computer

NOTICE: To avoid losing data, save and close any open files and exit any open programs before you turn off your computer.

1.Shut down the operating system:

a.Save and close any open files, exit any open programs, click the Start button, and then click Turn Off Computer.

b.In the Turn off computer window, click Turn off.

The computer turns off after the operating system shutdown process finishes.

2.Ensure that the computer and any attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut down your operating system, press and hold the power button for 4 seconds.

Before Working Inside Your Computer

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

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.

CAUTION: 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 processor by its edges, not by its pins.

NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not covered by your warranty.

NOTICE: 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 you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.

NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer.

1. Turn off your computer.

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

2.Disconnect any telephone or telecommunication lines from the computer.

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

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.

4. Open the computer cover.

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.

Power Supply DC Connector Pin Assignments

The 250-W power supply can operate from an AC power source of 115 VAC or 230 VAC at 50 – 60 Hz. The power supply provides the DC operating voltages and currents listed in the following table.

Output Voltage1	Minimum Current (A)	Maximum Current (A)2
+12 VDC	0.0	16.03
+5 VDC	1.0/0.24	22.0
+3.3 VDC	0.1/0.05	18.0
-	-	-
–12 VDC	0.0	1.0
+5 VFP	0.0	2.0

1Outputs will meet and not exceed SELV requirements per electrical standards, i.e. UL 60950, IEC 60950, EN60950 PAR.2.3.

2Maximum continuous combined load on +5 VDC and +3.3 VDC outputs will not exceed 150 watts.

3Peak +12 VDC output power (up to 17.0 amps) will not exceed 15 seconds in duration. Under this condition, tolerance on the +12v output, is allowed to be +/- 10%.

4+5 VDC minimum load will be 0.2A when there is a minimum load of 0.3A on the +12 VDC and 0.42A on the +3.3 VDC outputs simultaneously. +5V min load is 1A for load transient tests.

5In system applications where +3.3VDC is not used, all other outputs will stay within regulation while the +3.3 VDC output

is in a zero load condition.

System Messages

Power Lights

The power button light located on the front of your computer illuminates and blinks or remains solid to indicate different states:

If the power light is green, the power status is good and the computer is functioning properly.

If the power light is green and the computer is not responding, see Network Lights.

If the power light is blinking green, the computer is in standby mode. Press a key on the keyboard or move the mouse to resume normal operation.

If the power light is off, the computer is either turned off or is not receiving power.

Reseat the power cable into both the power connector on the back of the computer and the electrical outlet.

If the computer is plugged into a power strip, ensure that the power strip is plugged into an electrical outlet and that the power strip is turned on. Also bypass power protection devices, power strips, and power extension cables to verify that the computer turns on properly.

Ensure that the electrical outlet is working by testing it with another device, such as a lamp.

Ensure that the main power cable and front panel cable are securely connected to the system board.

If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.

Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).

Ensure that the processor power cable is securely connected to the system board.

If the power light is steady amber, a device might be malfunctioning or incorrectly installed.

Remove and then reinstall the memory modules.

Remove and then reinstall any cards.

Remove and then reinstall the graphics card, if applicable.

Diagnostic Lights

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.

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.

Light Pattern

Problem Description

The computer is in a normal off condition or a possible pre-BIOS failure has occurred.

Memory modules are detected, but a memory failure has occurred.

Suggested Resolution

Plug the computer into a working electrical outlet and press the power button.

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

If you have two or more memory modules installed, remove the modules, reinstall one memory 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.

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

If the problem persists, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance.

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.
