Start

button, and then click

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.

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

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.

Setting Up Your Computer

CAUTION: Before performing any of the procedures in this section, follow the safety instructions in

Product Information Guide.

NOTICE: If your computer has an expansion card installed (such as a modem card), connect the appropriate cable

to the card, not to the connector on the back panel.

NOTICE: To help allow the computer to maintain proper operating temperature, ensure that you do not place the

computer too close to a wall or other storage compartment that might prevent air circulation around the chassis. See your Product Information Guide for more information.

NOTE: Before you install any devices or software that did not ship with your computer, read the documentation

that came with the device or software, or contact the vendor to verify that the device or software is compatible with your computer and operating system.

You must complete all the steps to properly set up your computer. See the appropriate figures that follow the instructions.

NOTICE: Do not attempt to operate a PS/2 mouse and a USB mouse simultaneously.

Connect the keyboard and mouse.

NOTICE: Do not connect a modem cable to the network adapter connector. Voltage from telephone

communications can cause damage to the network adapter

Connect the modem or network cable.

Insert the network cable, not the telephone line, into the network connector. If you have an optional modem, connect the telephone line to the modem.

Connect the monitor.

Align and gently insert the monitor cable to avoid bending connector pins. Tighten the thumbscrews on the cable connectors.

NOTE: Some monitors have the video connector underneath the back of the screen. See the documentation

that came with your monitor for its connector locations.

Connect the speakers.

Connect power cables to the computer, monitor, and devices and connect the other ends of the power cables to electrical outlets.

NOTICE: To avoid damaging a computer with a manual voltage-selection switch, set the switch for the voltage that

most closely matches the AC power available in your location.

NOTICE: In Japan, the voltage selection switch must be set to the 115-V position even though the AC power

available in Japan is 100 V.

Verify that the voltage selection switch is set correctly for your location.

Your computer has a manual voltage-selection switch. Computers with a voltage selection switch on the back panel must be manually set to operate at the correct operating voltage.

Diagnostic Lights

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the

Product Information Guide.

To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4" on the front or back panel. The lights can be "off" or green. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. If the POST portion of system boot completes successfully, all four lights display solid green for a short time, and then turn off.

If the computer malfunctions during the POST process, the pattern displayed on the LEDs may help identify where in the process the computer halted. If the computer malfunctions after a successful POST, the diagnostic lights do not indicate the cause of the problem.

NOTE: The orientation of the diagnostic lights may vary depending on the system type. The diagnostic lights can be

either vertically or horizontally oriented.

Light Pattern Problem Description Suggested Resolution

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

The diagnostic lights are not lit after the computer successfully boots to the operating system.

A possible BIOS failure has occurred; the computer is in recovery mode.

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.

If your computer beeps during start-up:

Write down the beep code.

See "Dell Diagnostics" on page 21 to identify a more serious cause.
