Replacing the Gateway 450 Keyboard

This package includes a replacement keyboard for your Gateway 450 notebook

and these printed instructions.

Tools you need

You need a small Phillips and flat blade screwdriver to replace the keyboard.

Preventing static electricity discharge

The components inside your computer are extremely sensitive to static

electricity, also known as electrostatic discharge (ESD).

Before replacing the keyboard, follow these guidelines:

■Turn off the computer power.

■Wear a grounding wrist strap (available at most electronics stores) and

attach it to a bare metal part of the computer.

■Touch a bare metal surface on the back of the computer.

■Unplug the power cord and modem and network cables.

■Remove the battery.

Caution ESD can permanently damage electrostatic

discharge-sensitive components in the computer. Prevent

ESD damage by following ESD guidelines every time you

open the computer case.

Warning To avoid exposure to dangerous electrical voltages and

moving parts, turn off your computer and unplug the power

cord and modem and network cables before opening the

case.

Warning To prevent risk of electric shock, do not insert any object

into the vent holes of the notebook.

Before working with computer components, follow these guidelines:

■Avoid static-causing surfaces such as carpeted floors, plastic, and packing

foam.

■Remove components from their antistatic bags only when you are ready

to use them. Do not lay components on the outside of antistatic bags

because only the inside of the bags provide electrostatic protection.

To remove the keyboard:

1Follow the guidelines under “Preventing static electricity discharge” on

page 1.

2Shut down your notebook.

3Unplug the AC adapter and modem and network cables.

4Remove the main battery and optional secondary battery.

5Open the LCD panel to the normal viewing position.

Warning To avoid injury, disconnect the AC adapter and modem and

network cables before removing the keyboard. Replace the

keyboard before reconnecting power.
