System Setup
Setting up your system
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.
2
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
Starting your system
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 the computer and monitor are plugged into an AC outlet
■
or power strip and that the power strip is turned on.
Make sure your computer and peripherals are turned off
and unplugged from the power outlet when you connect
peripherals to the computer.
To start the system:
If you have connected the system components to a power strip, make
1
sure all the system components are turned off, then turn on the power
strip.
Turn on the monitor by pressing its power button.
2
System Setup
10
Turn on the computer by pressing its power button. The light-emitting
3
diode (LED) in the power button is lit when the power is on.
Power button
and power LED
Turn on any other components connected to the computer, such as
4
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.

Understanding the Power-On Self-Test
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 T

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.

Preventing static electricity
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.
3
Caution
To prevent static electricity discharge:
Turn off the computer power.
1
Touch a bare metal surface on the back of the computer.
2
Unplug all power cords from AC outlets and disconnect the modem cable
3
(if installed).
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.

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.

Opening the case
Important
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
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.
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:
Turn off the computer and disconnect all power cords.
1
Remove the thumbscrews from the back of the side panel and unlock
2
the chassis lock (if applicable).

Closing the case
Replace the chassis cover as soon as you finish installing or removing
components so that dust and dirt (which can damage the computer) do not
collect inside the computer.
To replace the bezel:
Holding the bezel at an angle to the front of the chassis, place the hinge
1
tabs on the right side of the bezel in the appropriate slots in the front
of the chassis.
Swing the left side of the bezel toward the chassis until the retaining tabs

snap into place.
Four hinge tabs are located
on the right side of the bezel
and are not visible in this

To replace the chassis cover:
Holding the left side panel at an angle to the chassis and 3/4-inch to the
1
rear, engage the retaining strip on the bottom edge of the panel with the
lip at the bottom edge of the chassis.
Swing the top of the panel toward the chassis, engaging the retaining
2
tabs on the top edge of the side panel with the slots on the chassis.
Slide the panel toward the front of the chassis 3/4-inch, securing it into

place.
Reinstall the thumbscrews and lock the case (if applicable).

System Components
The system board
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.
Removing the system board
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
To remove the system board:
Turn off the system and disconnect the power cord, modem cord (if
1
installed), and all external peripheral devices.
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.

Open the case by following the instructions on page 17. (See “Preventing

static electricity” on page 15.)
Place the chassis gently on its right side.
