CAUTION: Safety Instructions

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

General

•Do not attempt to service the computer yourself unless you are a trained service technician. Always follow installation instructions closely.

•To help prevent electric shock, plug the computer and device power cables into properly grounded electrical outlets. These cables are equipped with 3-prongplugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a3-wirecable with properly grounded plugs.

•To help avoid the potential hazard of electric shock, do not use your computer during an electrical storm.

•To help avoid the potential hazard of electric shock, do not connect or disconnect any cables or perform maintenance or reconfiguration of this product during an electrical storm.

•If your computer includes a modem, the cable used with the modem should be manufactured with a minimum wire size of 26 American wire gauge (AWG) and an FCCcompliant RJ-11modular plug.

•Before you clean your computer, disconnect the computer from the electrical outlet. Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable substances.

•To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before disconnecting a device from the computer.

w w w. d e l l . c o m s u p p o r t . d e l l . c o m

CAUTION: Safety Instructions(continued)

•To avoid shorting out your computer when disconnecting a network cable, first unplug the cable from the network adapter on the back of your computer, and then from the network jack. When reconnecting a network cable to your computer, first plug the cable into the network jack, and then into the network adapter.

•To help protect your computer from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).

•Ensure that nothing rests on your computer’s cables and that the cables are not located where they can be stepped on or tripped over.

•Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting out interior components.

•Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath your computer; do not place your computer in a closed-inwall unit or on a bed, sofa, or rug.

When Using Your Computer

As you use your computer, observe the following safe-handlingguidelines.

CAUTION: Do not operate your computer with any cover(s) (including computer covers, bezels, filler brackets,front-panelinserts, and so on) removed.

•Your computer is equipped with one of the following:

–A fixed-voltagepower supply — Computers with afixed-voltagepower supply do not have a voltage selection switch on the back panel and operate at only one voltage (see the regulatory label on the outside of the computer for its operating voltage).

–An auto-sensingvoltage circuit — Computers with anauto-sensingvoltage circuit do not have a voltage selection switch on the back panel and automatically detect the correct operating voltage.

–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.

NOTICE: To help 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. For Japan, the voltage selection switch must be set to the115-Vposition even though the AC power available in Japan is 100 V. Also, ensure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.

•Before working inside the computer, unplug the computer to help prevent electric shock or system board damage. Certain system board components continue to receive power any time the computer is connected to AC power.

w w w. d e l l . c o m s u p p o r t . d e l l . c o m

When Using Your Computer (continued)

When Working Inside Your Computer

Before you open the computer cover, perform the following steps in the sequence indicated.

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 after turning off the computer before removing a component from the system board or disconnecting a device from the computer.

1Shut down the computer (page 33).

2Turn off your computer and any devices connected to the computer.

3Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slotopenings at the back of the computer, before touching anything inside your computer.

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

4Disconnect your computer and devices, including the monitor, from their electrical outlets. Also, disconnect any telephone or telecommunication lines from the computer.

Doing so reduces the potential for personal injury or shock.

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

•When you disconnect a cable, pull on its connector or on its strain-reliefloop, 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 aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.

When Using Your Computer (continued)

•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.

CAUTION: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.

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):

•Do not remove components from their antistatic packing material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, discharge static electricity from your body.

•When transporting an electrostatic sensitive component, first place it in an antistatic container or packaging.

•Handle all electrostatic sensitive components in a static-safearea. If possible, use antistatic floor pads and workbench pads.

Ergonomic Computing Habits

CAUTION: Improper or prolonged keyboard use may result in injury.

CAUTION: Viewing the monitor screen for extended periods of time may result in eye strain.

For comfort and efficiency, observe the ergonomic guidelines in the Tell Me How help file when setting up and using your computer. To access the help file, see page 38.

w w w. d e l l . c o m s u p p o r t . d e l l . c o m

When Using Your Computer (continued)

Battery Disposal

Your computer uses a lithium coin-cellbattery. The lithiumcoin-cellbattery is along-lifebattery, and it is very possible that you will never need to replace it. However, should you need to replace it, see page 117.

Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.

HINT: Ensure that you follow all copyright laws when you create CDs.

HINT: The information in this section also applies to using Easy CD Creator Basic with a DVD+RW or a DVD+R drive.

HINT: Some music and game CDs are copyprotected. If you have a CD that cannot be copied, you must use the original CD for everyday use.

Copying CDs

This section applies only to computers that have a CDor DVD-recordingdevice.

The information in this section is based on the Roxio Easy CD Creator Basic documentation that came with your computer. See the following section, 'Using Easy CD Creator Basic,' for instructions on how to locate that documentation.

To burn CDs, you need to use CD-burnersoftware. Roxio Easy CD Creator Basic is your computer'sCD-burnersoftware. The software includes these project programs that enable you to record specialty CDs for different types of uses:

•DirectCD allows you to format a blank CD-RorCD-RWdisc so that you can use Microsoft® Windows® Explorer to drag and drop data files to theCD-RWdrive. You can use aDirectCD-formattedCD-RWdisc like another hard drive on your computer becauseCD-RWdiscs are fully rewritable(CD-Rdiscs can be used with DirectCD, but that media type has overwritinglimitations—see'Using BlankCD-RDiscs or BlankCD-RWDiscs' for recording media differences).

•MusicCD allows you to burn custom music CDs.

•DataCD allows you to copy a variety of your documents, such as spreadsheet or accounting files, to a CD for permanent storage.

•Disc Copier allows you to make a backup copy of almost any type of CD. This program allows you to make a copy of a CD for everyday use so that you can archive and save the original copy. (Disc Copier is titled 'CD Copier' in some versions of Roxio CD Creator Basic.)

All four project programs are available on the Easy CD Creator Basic Select a Project menu screen. To view theSelect a Project menu screen, click the

Start button, point to All Programs→ Roxio Easy CD Creator, and then click Project Selector.

Using Easy CD Creator Basic

See the Easy CD Creator Basic documentation for instructions on how to use the program, information about different recording techniques, and CD media limitations. The Easy CD Creator Basic documentation is located in the Microsoft® Windows® XP Help and Support Center (see 'Finding Information for Your Computer' on page 15). The documentation is also provided on theDell Dimension ResourceCD, which is included with your computer. Each Easy CD Creator Basic project program also has thorough online help files.

Using Blank CD-RDiscs or BlankCD-RWDiscs

Your CD-RWdrive writes to two different types of recordingmedia—CD-RandCD-RWdiscs. Use blankCD-R(CD-Recordable)disks to record music or permanently store data files. After creating aCD-Rdisc, you cannot write to that disc again without changing your method of recording (see the Roxio documentation for more information). Use blankCD-RW(CD-ReWritable)discs when you want to write, erase, rewrite, and update your files onto CDs.

Helpful Tips

•You must use the Easy CD Creator Basic project programs to copy and record all music and data CDs. You can use Windows Explorer to drag and drop files to a CD-RorCD-RWdisc only after you first use DirectCD to format the disc.

•You must use CD-Rdiscs to burn music CDs that you want to play in regular stereos.CD-RWdiscs do not play in most home or car stereos.

•If you want to copy files from the Internet or files from a floppy or Zip drive, copy those files to your hard drive first, and then burn your CD. Your CD-RWdrive requires a steady stream of data to properly record. Direct Internet downloads, floppy drives, and Zip drives may not be able to provide a steady data stream to yourCD-RWdrive.

•Music MP3 files can be played only on MP3 players or on computers that have MP3 software installed.

•Ensure that you set the sampling rate to at least 128 Kbps when you burn MP3 files to a CD. Otherwise, recording errors may occur.

w w w. d e l l . c o m s u p p o r t . d e l l . c o m

HINT: If you have aDVD/CD-RWcombo drive and you experience recording problems, first check for available software patches at the Dell Support website atsupport.dell.com and if necessary, the Roxio support website atsupport.roxio.com.

•Do not burn a blank CD-RorCD-RWdisc to its maximum capacity; for example, do not copy a650-MBfile to a650-MBblank CD. TheCD-RWdrive needs 1 or 2 MB of the blank CD to finalize the recording.

•Use a blank CD-RWdisc to practice CD recording until you are familiar with CD recording techniques. If you make a mistake, you can erase theCD-RWdisc and try again. You can also use blankCD-RWdiscs to test music file projects before you record the project permanently to a blankCD-Rdisc.

•See the Roxio support website at support.roxio.com for additional helpful tips.

How to Copy a CD

The procedure assumes that your computer is equipped with a single CD-RWdrive (without an additional CD drive). If your computer is equipped with both types of drives, see the Roxio documentation for instructions on how to copy CDs from a CD drive to aCD-RWdrive.

1Click the Startbutton, point to All Programs→ Roxio Easy CD Creator, and then click Project Selector.

The Select a Project window appears.

2Click Disc Copier. (Disc Copier is titled 'CD Copier' in some versions of Easy CD Creator Basic.)

The Disc Copier window appears and displays yourCD-RWdrive in theCopy from and theRecord to lists.

3Insert the source CD that you want to copy into the CD-RWdrive.

The Disc Copier project program briefly checks the source CD in the CD-RWdrive to ensure that it is a readable CD.

4Click Copy.

Depending on the size of the files that are being copied, the copy process may take a few minutes.

5After the source CD is copied, remove the source CD from the CD-RWdrive tray.

The CD-RWdrive tray opens automatically after the source CD is copied.

6Insert a blank CD into the CD-RWdrive and close the tray. The recording starts automatically.

7After the recording completes, click OK.

Diagnostic Lights

To help you troubleshoot a problem, your computer is equipped with four lights on the back panel labeled 'A,' 'B,' 'C,' and 'D' (see page 78). These lights can be yellow or green. When the computer starts normally, the lights flash. After the computer starts, the lights remain 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 on page 9.

• Install the memory modules (see page 93) in memory connectors RIMM1 (located closest to the microprocessor) and RIMM2 and ensure that, if no additional memory is used, CRIMMs are installed in memory connectors RIMM3 and RIMM4.

• If you installed memory modules in memory connectors RIMM3 and RIMM4 that were not purchased from Dell, remove the modules and replace them with the CRIMMs that were originally installed in your computer.

• If available, install Dell memory of the same type into your computer (see page 93).

• If the problem persists, contact Dell (see page 120).

2 If the problem persists, reinstall the card that you removed (see page 88), 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' on page 70).

4 If the problem persists, contact Dell (see page 120).

Drivers

What Is a Driver?

A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require a driver program.

A driver acts like a translator between the device and the programs that use the device. Each device has its own set of specialized commands that only its driver recognizes.

w w w. d e l l . c o m s u p p o r t . d e l l . c o m

Many drivers such as the keyboard driver come with your Microsoft® Windows® operating system. You may need to install drivers if you:

•Upgrade your operating system

•Reinstall your operating system

•Connect or install a new device

If you experience a problem with any device, perform the steps in the following sections to identify whether the driver is the source of your problem and if necessary, to update the driver.

Your original memory modules must be installed as a pair in either connectors RIMM1 and RIMM 2 or RIMM 3 and RIMM4. Do not pair one original memory module with one new memory module in connectors RIMM1 and RIMM2 or RIMM3 and RIMM4. Otherwise, your computer may not start properly.

RDRAM technology requires that all memory connectors have either a memory module or a continuity module installed. Memory modules and continuity modules are easily identified—memorymodules have a metal cover on one side of the module and continuity modules do not.

HINT: The metal cover on a memory module is manufactured in various colors. The color of the metal cover has no effect on the module’s performance.

HINT: Mixed pairs of PC1066 and PC800 modules all function as PC800.

Memory modules are the actual components that provide memory for the microprocessor; continuity modules are used only to complete the memory circuit if memory modules are not installed in all of the memory connectors.

Another RDRAM requirement is that memory modules must be installed in pairs of matched memory size. This means that if you purchased your computer with 128 MB of memory installed and you want to add another 128 MB of memory, you must remove the two continuity modules and replace them with two64-MBmemory modules.

NOTICE: You can only install continuity modules in connectors RIMM 3 and RIMM4.

The only two valid memory configurations are:

•A pair of matched memory modules installed in connectors RIMM1 and RIMM2 with continuity modules installed in connectors RIMM3 and RIMM4

or

•A pair of matched memory modules installed in connectors RIMM1 and RIMM2 and another matched pair installed in connectors RIMM3 and RIMM4
