Before You Begin

Before Working Inside Your Computer

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

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

safety instructions in the Product Information Guide.

NOTICE: 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.

10 Quick Reference Guide

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 pull-tab, not

on the cable itself. Some cables have connectors 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.

Turn off your computer (see "Turning Off Your Computer" on page 12).

CAUTION: Never apply power to the computer when the cover has been removed.

NOTICE: To disconnect a network cable, first unplug the cable from your computer

and then unplug the cable from the network device.

Disconnect all telephone or network cables from the computer.

Disconnect your computer and all attached devices from their electrical outlets.

Press the power button to ground the system board.

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 static electricity, which could harm internal components.

Adding and Replacing Parts

This section 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" on page 12 and "Before Working Inside Your Computer" on page 10.

• You have read the safety information in the Dell™

Guide

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

Setting Up Your Computer

Installing Your Computer in an Enclosure

Installing your computer in an enclosure can restrict the airflow and impact your computer’s performance, possibly causing it to overheat. Follow the guidelines below when installing your computer in an enclosure:

NOTICE: The operating temperature specifications indicated in this manual

reflects the maximum ambient operating temperature. The room ambient temperature needs to be a consideration when installing your computer in an enclosure. For example, if the ambient room temperature is at 25°C (77°F), depending on your computer’s specifications, you only have 5° to 10°C (9° to 18°F) temperature margin before you reach your computer’s maximum operating temperature. For details about your computer’s specifications, see the online User’s Guide.

• Leave a 10.2 cm (4 in) minimum clearance on all vented sides of the computer to permit the airflow required for proper ventilation.

• If your enclosure has doors, they need to be of a type that allows at least 30 percent airflow through the enclosure (front and back).

Quick Reference Guide 13

• If your computer is installed in a corner on a desk or under a desk, leave at least 5.1 cm (2 in) clearance from the back of the computer to the wall to permit the airflow required for proper ventilation.

NOTICE: Do not install your computer in an enclosure that does not allow airflow.

Restricting the airflow impacts your computer’s performance, possibly causing it to overheat.

Connecting to the Internet

NOTE: ISPs and ISP offerings vary by country.

To connect to the Internet, you need a modem or network connection and an Internet service provider (ISP). Your ISP will offer one or more of the following Internet connection options:

• DSL connections that provide high-speed Internet access through your existing telephone line or cellular telephone service. With a DSL connection, you can access the Internet and use your telephone on the same line simultaneously.

• Cable modem connections that provide high-speed Internet access through your local cable TV line.

• Satellite modem connections that provide high-speed Internet access through a satellite television system.

• Dial-up connections that provide Internet access through a telephone line. Dial-up connections are considerably slower than DSL and cable (or satellite) modem connections.

• Wireless LAN connections that provide Internet access using Bluetooth wireless technology.

If you are using a dial-up connection, connect a telephone line to the modem connector on your computer and to the telephone wall jack before you set up your Internet connection. If you are using a DSL or cable/satellite modem connection, contact your ISP or cellular telephone service for setup instructions.

Moving Information to a New Computer

You can use your operating system "wizards" to help you transfer files and other data from one computer to another—for example, from an old computer to a new computer. For instructions, see the following section that corresponds to the operating system that your computer is running.

Microsoft® Windows® XP (Optional)

The Microsoft Windows XP operating system provides the Files and Settings Transfer Wizard to move data from a source computer to a new computer. You can transfer data, such as:

• E-mail messages

• Toolbar settings

• Window sizes

• Internet bookmarks

Quick Reference Guide 19

You can transfer the data to the new computer over a network or serial connection, or you can store it on removable media, such as a writable CD, for transfer to the new computer.

NOTE: You can transfer information from an old computer to a new computer by

directly connecting a serial cable to the input/output (I/O) ports of the two computers. To transfer data over a serial connection, you must access the Network Connections utility from the Control Panel and perform additional configuration steps, such as setting up an advanced connection and designating the host computer and the guest computer.

For instructions on setting up a direct cable connection between two computers, see Microsoft Knowledge Base Article #305621, titled How to Set Up a Direct Cable Connection Between Two Computers in Windows XP. This information may not be available in certain countries.

For transferring information to a new computer, you must run the Files and Settings Transfer Wizard. You can use the optional Operating System media for this process or you can create a wizard disk with the Files and Settings Transfer Wizard.

Quick Reference Guide 23

Printer Cable

Your printer connects to your computer with either a USB cable or a parallel cable. Your printer may not come with a printer cable, so if you purchase a cable separately, ensure that it is compatible with your printer and computer. If you purchased a printer cable at the same time you purchased your computer, the cable may arrive in the computer’s shipping box.

Connecting Two Monitors

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

safety instructions in the Product Information Guide.

If you purchased a graphics card that supports dual monitors, follow these instructions to connect and enable your monitors. The instructions tell you how to connect either two monitors (each with a VGA connector), one monitor with a VGA connector and one monitor with a DVI connector, or a TV.

NOTICE: If you are connecting two monitors that have VGA connectors, you must

have the optional DVI adapter to connect the cable. If you are connecting two flat-panel monitors, at least one of them must have a VGA connector. If you are connecting a TV, you may connect only one monitor (VGA or DVI) in addition to the TV.

Connecting Two Monitors With VGA Connectors

Shutdown your system.

NOTE: If your computer has integrated video, do not connect either monitor to the

integrated video connector. If the integrated video connector is covered by a cap, do not remove the cap to connect the monitor or the monitor will not function.

Connect one of the monitors to the VGA (blue) connector on the back of the computer.

Connect the other monitor to the optional DVI adapter and connect the DVI adapter to the DVI (white) connector on the back of the computer.

Restart your system.

Power Protection Devices

Several devices are available to protect against power fluctuations and failures:

• Surge protectors

• Line conditioners

• Uninterruptible power supplies (UPS)

Surge Protectors

Surge protectors and power strips equipped with surge protection help prevent damage to your computer from voltage spikes that can occur during electrical storms or after power interruptions. Some surge protector manufacturers include warranty coverage for certain types of damage. Carefully read the device warranty when choosing a surge protector. A device with a higher joule rating offers more protection. Compare joule ratings to determine the relative effectiveness of different devices.

26 Quick Reference Guide

NOTICE: Most surge protectors do not protect against power fluctuations or

power interruptions caused by nearby lightning strikes. When lightning occurs in your area, disconnect the telephone line from the telephone wall jack and disconnect your computer from the electrical outlet.

Many surge protectors have a telephone jack for modem protection. See the surge protector documentation for modem connection instructions.

NOTICE: Not all surge protectors offer network adapter protection. Disconnect the

network cable from the network wall jack during electrical storms.

Line Conditioners

NOTICE: Line conditioners do not protect against power interruptions.

Line conditioners are designed to maintain AC voltage at a fairly constant level.

Uninterruptible Power Supplies

NOTICE: Loss of power while data is being saved to the hard drive may result in

data loss or file damage.

NOTE: To ensure maximum battery operating time, connect only your computer to

a UPS. Connect other devices, such as a printer, to a separate power strip that provides surge protection.

A UPS protects against power fluctuations and interruptions. UPS devices contain a battery that provides temporary power to connected devices when AC power is interrupted. The battery charges while AC power is available. See the UPS manufacturer documentation for information on battery operating time and to ensure that the device is approved by Underwriters Laboratories (UL).
