NOTICE: Do not attempt to service the computer yourself, except as explained in your online Dell documentation or otherwise provided to you. 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. 1 2 3 Perform an orderly computer shutdown using the operating system menu. Turn off your computer and any devices. Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot openings 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. 4 Disconnect your computer and devices from their power sources. 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 strainrelief 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 aligned to avoid bending any connector pins. Also, before you connect a cable, make sure both connectors are correctly oriented and aligned. 9 w w w. d e l l . c o m | s u p p o r t . d e l l . c o m · 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. Discard used batteries according to the manufacturer's instructions. 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): · 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. When transporting a sensitive component, first place it in an antistatic container or packaging. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads. · · The following notice may appear throughout this document to remind you of these precautions: NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions at the front of this guide. 10 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 following ergonomic guidelines when setting up and using your computer: · Position your computer so that the monitor and keyboard are directly in front of you as you work. Special shelves are available (from Dell and other sources) to help you correctly position your keyboard. Set the monitor at a comfortable viewing distance (usually 510 to 610 millimeters [20 to 24 inches] from your eyes). Make sure the monitor screen is at eye level or slightly lower when you are sitting in front of the monitor. Adjust the tilt of the monitor, its contrast and brightness settings, and the lighting around you (such as overhead lights, desk lamps, and the curtains or blinds on nearby windows) to minimize reflections and glare on the monitor screen. Use a chair that provides good lower back support. Keep your forearms horizontal with your wrists in a neutral, comfortable position while using the keyboard or mouse. Always leave space to rest your hands while using the keyboard or mouse. Let your upper arms hang naturally at your sides. Sit erect, with your feet resting on the floor and your thighs level. When sitting, make sure the weight of your legs is on your feet and not on the front of your chair seat. Adjust your chair's height or use a footrest, if necessary, to maintain proper posture. Vary your work activities. Try to organize your work so that you do not have to type for extended periods of time. When you stop typing, try to do things that use both hands. · · · · · · · · · · 11 w w w. d e l l . c o m | s u p p o r t . d e l l . c o m 1 5 2 4 3 1 Monitor screen at or below eye level 2 Monitor and keyboard positioned directly in front of the user 3 Feet flat on the floor 4 Arms at desk level 5 Wrists relaxed and flat 12 SECTION 1 A b o u t Yo u r C o m p u t e r Finding Information and Assistance Front View Back View Inside Your Computer Removing and Attaching the Computer Stand w w w. d e l l . c o m | s u p p o r t . d e l l . c o m w w w. d e l l . c o m | s u p p o r t . d e l l . c o m Finding Information and Assistance The following table lists the resources that Dell provides as support tools.

For example, you must connect most devices to a particular input/output (I/O) port or connector to operate properly. Also, external devices like a mouse or printer usually require you to load device drivers into computer memory before they will work. · Always attach external devices while your computer is turned off. Then turn on the computer before turning on any external devices, unless the documentation for the device specifies otherwise. (If the computer does not seem to recognize the device, try turning on the device before turning on the computer.) 26 Abo u t You r C o mp u t er NOTICE: When you disconnect external devices from the back of the computer, wait 5 seconds after turning off the computer before you disconnect any devices to avoid possible damage to the system board. Parallel Connector This is used to connect printers. Default designation is LPT1. Mouse Connector Turn off the computer and any attached devices before connecting a mouse to the computer. If your computer uses Microsoft Windows 2000 or Windows NT 4.0, Dell installed the necessary mouse drivers on your hard drive. USB Connectors These are used to attach USB-compliant devices such as keyboards, mice, printers, and computer speakers to your computer. NOTE: The integrated parallel port is automatically disabled if the computer detects an installed expansion card containing a parallel port configured to the same address as specified in "Additional System Setup Options." Integrated Network Adapter Connector The network adapter, which includes a Remote Wake Up feature, has the following lights: · A yellow activity light flashes when the computer is transmitting or receiving network data. (A high volume of network traffic may make this light appear to be in a steady "on" state.) A dual-colored link integrity light, which is green when there is a good connection between a 10-megabit per second (Mbps) network and the network adapter and orange when there is a good connection between a 100-Mbps network and the network adapter. When the light is off, the computer is not detecting a physical connection to the network. · Network Cable Requirements The network adapter connector attaches an unshielded twisted pair (UTP) Ethernet cable to your computer. Press one end of the UTP cable to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending on your network configuration, and press the other end of the UTP cable into the network adapter connector until the cable snaps securely into place Dell recommends the use of Category 5 wiring and connectors for our customers' networks. Abo u t Yo u r C o m p u te r 27 w w w. d e l l . c o m | s u p p o r t . d e l l . c o m Line-In Jack This jack is used to attach record/playback devices such as cassette players, CD players, and VCRs.
