System Setup |

Use the instructions on the poster that came with your system to assemble your system. You can prepare a safer working environment before assembling your system by following the guidelines listed below.
■Provide a clean, flat, and stable surface for your system. Allow at least 12 inches at the rear of the computer for cabling and air circulation.
■Obtain a grounded (three-prong) AC surge-protected power strip. A surge-protected power strip helps protect against AC line spikes.
■Protect your system from extreme temperature and humidity. Do not expose your system to direct sunlight, heater ducts, or other heat-generating objects.
■Keep your computer away from equipment that generates magnetic fields, such as unshielded stereo speakers. Even a telephone placed too close to the computer may cause interference.
■Plug the computer into a wall outlet or power strip that is easily accessible. When you turn off the computer with the power button, some electricity still flows through the computer. To remove all power from the computer, you need to unplug the power cord.
Important Keep the computer boxes and packing material, in case you need to send the computer to Gateway for repairs. If you return your computer in different packaging, your warranty may be void.
Setting up your system |
9 |
Before you start your system for the first time:
■Make sure that the voltage selector switch on the back of the computer is still set to the correct voltage for your area. This switch is set at the factory to the correct voltage (see “Rear panel” on page 4 for voltage selector switch location).
■Make sure all cables are firmly connected to the proper ports on the rear panel of the computer.
Caution Make sure your computer and peripherals are turned off and unplugged from the power outlet when you connect peripherals to the computer.
■Make sure the computer and monitor are plugged into an AC outlet or power strip and that the power strip is turned on.
To start the system:
1If you have connected the system components to a power strip, make sure all the system components are turned off, then turn on the power strip.
2Turn on the monitor by pressing its power button.
10 System Setup
3Turn on the computer by pressing its power button. The light-emitting diode (LED) in the power button is lit when the power is on.
Power button and power LED
4Turn on any other components connected to the computer, such as speakers, a printer, or a scanner.
If nothing happens when you turn on the system:
■Recheck the power cables to make sure that they are securely plugged in and that your power strip (if you are using one) is plugged in and turned on.
■Make sure the monitor is connected to the computer, plugged into the power strip or AC outlet, and turned on. You may also need to adjust the brightness and contrast controls on the monitor.
Important Wait until the startup procedure is finished before loading a diskette in the diskette drive, or the computer may search the diskette for startup information.
Starting your system |

When you turn on your computer, the power-on self-test (POST) routine checks the system memory and components. To see this information on the screen, press TAB during POST. Press ESC to bypass the remaining memory count.
The system displays an error message if POST finds any problems. Write down the error message that appears. If you continue to experience problems, this error message may help technical support diagnose the cause.
The first time you start your computer, the operating system takes a few minutes to set up.
Refer to your software documentation for specific questions regarding software.
To complete the operating system setup:
1After the computer starts, the start-up wizard opens. Continue by clicking
Next.
2Type the requested information in the appropriate text boxes. When you have finished typing the information, continue by clicking Next.
3Continue following the instructions and selecting options in the start-up wizard dialog boxes, clicking Next to move through the dialog boxes, until the wizard tells you to restart your computer.
Most of the dialog boxes that open in the start-up wizard have a button that takes you back to previous dialog boxes, in case you need to change or correct the information you typed.
4Restart your system. The setup is complete.
12 System Setup

Before opening the computer case, read and follow these precautions to prevent damage from static electricity. When opening your computer case, always perform the following procedure.
Caution Static electricity can permanently damage electronic components in your computer. Prevent electrostatic damage to your computer by following static electricity precautions every time you open your computer case.
To prevent static electricity discharge:
1Turn off the computer power.
2Touch a bare metal surface on the back of the computer.
3Unplug all power cords from AC outlets and disconnect the modem cable (if installed).

Also follow these static electricity precautions:
■Avoid static-causing surfaces such as plastic and styrofoam in your work area.
■Remove the parts from their antistatic bag or container only when you are ready to use them. Do not lay parts on the outside of an antistatic bag or container because only the inside provides antistatic protection.
■Always hold cards by their edges and their metal mounting brackets. Avoid touching components on the cards and the edge connectors that connect to expansion slots. Never slide cards or other parts over any surface.

Important All references to front, rear, left or right on the computer are based on the computer being in a normal, upright position, as viewed from the front.
To work on the internal components of the computer, you must open the case, which has two removable parts:
■A left side cover panel that permits access to the interior of the case
■A bezel that covers the front of the chassis
Because the components inside your computer are extremely sensitive to static electricity, make sure to follow the precautions at the beginning of this chapter for avoiding static electricity damage. Only qualified personnel should open the system for maintenance. If you feel you are qualified to maintain the system yourself, make sure you are properly grounded before opening the system chassis.
Warning Avoid exposure to dangerous electrical voltages and moving parts, by turning off your computer and unplugging the power cord and modem cable (if installed) before removing the chassis cover.
To remove the left side cover panel:
1Turn off the computer and disconnect all power cords.
2Remove the thumbscrews from the back of the side panel and unlock the chassis lock (if applicable).

Components
The system board is the heart of the computer, which integrates the other elements of the system, such as the processor, memory, storage, networking, and communications, and lets them operate in a coordinated and useful way.
The system board is mounted on stand-off retention hooks on the right side of the chassis. The board is secured by two screws, one located on the back-right of the chassis, and one located inside the case.
Important All references to front, rear, left or right on the computer are based on the computer being in a normal, upright position, as viewed from the front.
To remove the system board:
1Turn off the system and disconnect the power cord, modem cord (if installed), and all external peripheral devices.
2Open the case by following the instructions on page 17. (See “Preventing static electricity” on page 15.)
