Replacing Gateway Notebook Components

Preparing your work space

Before performing maintenance on the notebook, make sure that your work space and

the notebook are correctly prepared.

■Wear a grounding (ESD) wrist strap, and use a grounded or dissipative work mat.

■Use a stable and strong table, and make sure that the table top is large enough to

hold each component as you remove it.

■Use bright lighting to make part identification easier.

■Keep your work surface free from clutter and dust that may damage components.

■Use a magnetized screwdriver for removing screws.

■When removing components that are attached to the notebook by a cable, unplug

the cable before removing the screws, when possible, to avoid damaging the cable.

■As you remove components and screws, lay them toward the rear of your work

surface (behind the notebook) or far enough to the side that your arms do not

accidentally brush them onto the floor.

■To help keep track of screws, try the following:

■Place each component’s screws in their own section of a parts sorter.

■Place each component’s screws next to the component on your work surface.

■Print the first page of each task, then place the page toward the rear of your

work surface. As you remove screws, place the screws in their respective boxes

on the page. Where screw measurements are shown, the first number indicates

screw head width, and the second number indicates screw length.

■After loosening screws that are deeply recessed in a hole (for example, on the

bottom of the base assembly), you can leave the screws in the holes if you place

small pieces of masking tape over the hole openings. When reassembling the

component, just remove the tape and tighten the screws.

■When you place flat-headed screws on your work surface, stand them on their

heads to prevent the screws from rolling off the table.

Preventing static electricity discharge

The components inside your notebook are extremely sensitive to static electricity, also

known as electrostatic discharge (ESD).

Before performing maintenance on the notebook, 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.

■Always hold components by their edges. Avoid touching the edge connectors.

Never slide components over any surface.

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

a bare metal part of your workbench or other grounded connection.

■Touch a bare metal surface on your workbench or other grounded object.

Important Before performing maintenance on the notebook, you should read

and understand the information in this section.

Warning To avoid exposure to dangerous electrical voltages and moving parts,

turn off your notebook and unplug the power cord, modem cable, and

network cable before opening the case.

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

holes of the notebook.

Caution Some of the procedures in this guide involve removing tape that holds

wires or components. Two types of tape are used in this Gateway

notebook:

■Mylar, non-conductive tape is typically transparent, with a red or

brown tint.

■Conductive tape is typically grey or silver.

If the existing tape cannot be reused, replace it with the same type

(conductivity) of tape. Both types of replacement tape should be

non-ESD generating tape.

Do not use cellophane tape.

Warning To avoid exposure to dangerous electrical voltages and moving parts,

turn off the notebook, remove the battery, and unplug the power cord,

modem cable, and network cable before opening the case. Replace

the cover before you restore power or reconnect the modem and

network cables.
