For more information, refer to the safety and warranty information that is provided with your computer. Customer safety is important.
In the unlikely event that you notice any of the following conditions, or if you have any safety concerns with your product, stop using the product and unplug it from the power source and telecommunication lines until you can speak to the Customer Support Center for further guidance. See Chapter 8, “Getting information, help, and service,” on page 55 for more information. v Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are cracked, broken, or damaged.
Danger Hazardous moving parts. Keep fingers and other body parts away. Attention Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer cool before opening the cover. Static electricity prevention Static electricity, although harmless to you, can seriously damage computer components and options. Improper handling of static-sensitive parts can cause damage to the part.
The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or better. For other countries, the suitable types shall be used accordingly. Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that can cause the cord to fray, crack, or crimp. This can present a safety hazard. Always route power cords so that they will not be walked on, tripped over, or pinched by objects. Protect power cord and power adapters from liquids.
Voltage-selection switch Some computers are equipped with a voltage-selection switch located near the power-cord connection point on the computer. If your computer has a voltage-selection switch, ensure that you set the switch to match the voltage available at your electrical outlet. Setting the voltage-selection switch incorrectly can cause permanent damage to the computer.
Be sure that the power outlet you are using is properly wired, easily accessible, and located close to the equipment. Do not fully extend power cords in a way that will stress the cords. Be sure that the power outlet provides the correct voltage and current for the product you are installing. Carefully connect and disconnect the equipment from the electrical outlet.

Chapter 1. Arranging your workspace To get the most from your computer, arrange both the equipment you use and your work area to suit your needs and the kind of work you do. Your comfort is of foremost importance, but light sources, air circulation, and the location of electrical outlets also can affect the way you arrange your workspace. Comfort Although no single working position is ideal for everyone, here are a few guidelines to help you find a position that suits you best.
Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen might be helpful. However, these filters might affect the clarity of the image on the screen; try them only after you have exhausted other methods of reducing glare. Dust buildup compounds problems associated with glare. Remember to clean your monitor screen periodically using a soft cloth moistened with a nonabrasive liquid glass cleaner. Air circulation Your computer and monitor produce heat.
Chapter 2. Setting up your computer Before you begin, make sure you set up your computer in the best possible work area that suits your needs and the kind of work you do. For more information, refer to Chapter 1, “Arranging your workspace,” on page 1. Note: Read “Important safety information” on page v before you set up your computer. The precautions and guidelines will help you work safely. Connecting your computer Use the following information when connecting your computer.
If your computer does not have a voltage selection switch, it is designed to operate only at the voltage provided in the country or region where it was originally purchased. Continue with step 2. 2. Your keyboard cable might have a standard keyboard connector 1 or a Universal Serial Bus (USB) connector 2 . Connect the keyboard cable to the appropriate keyboard connector. Note: Some models will have keyboards with a fingerprint reader.
v If you have a digital video interface (DVI) monitor, connect the cable to the connector as shown. Note: Your computer must have an adapter installed that supports the DVI monitor. 5. If you have a modem, connect the modem using the following information. E ON PH E ON PH E ON PH LINE PH E LIN ON E LIN LIN 1 2 3 E E This illustration shows the two connections on the back of the computer that are needed to set up your modem.
6. If you have audio devices, attach them using the following instructions. For more information about speakers, see steps 7 and 8. 1 Audio line-in 2 Audio line-out 3 Microphone 4 Headphone This connector receives audio signals from an external audio device, such as a stereo system. This connector sends audio signals from the computer to external devices, such as powered stereo speakers.
b. Connect the speakers to the computer. 9. Connect any additional devices that you have. Your computer might not have all connectors that are shown. 1394 1394 1 USB 2 Serial 3 S-video 4 Parallel 5 Ethernet 6 MIDI/joystick 7 IEEE 1394 Use this connector to attach a device that requires a USB connection, such as a keyboard, mouse, scanner, printer, or personal digital assistant (PDA).
Note: Refer to the Access Help online help system for more information about connectors. See “Access Help” on page 56 for instructions on how to open the online help system. Turning on power Turn on the monitor and other external devices first, and then turn on the computer. When the power-on self-test (POST) is finished, the logo window closes. If your computer has preinstalled software, the software installation program starts.
v Record your computer machine type, model, and serial number. If you need service or technical support, you will probably be asked for this information. For further information, see the safety and warranty information that is provided with your computer. Updating your operating system Microsoft makes updates available for various operating systems through the Microsoft Windows Update Web site.
