Replacing Gateway Notebook Components www.gateway.comImportantThis service guide is not intended to be

provided to individual users orconsumers. It cannot be provided to

anyone other than an authorized serviceprovider.

ImportantFor information on the notebooks

general maintenance, technical support,safety notices, and regulatory notices, see

the notebooks user guide.

ImportantIf you have suggestions regarding the

content of this guide, send an e-mail withthe subject Service Guide Comments to

[email protected].

Use this service guide to help plan maintenance tasks for the following Gateway notebooks:

450RGH 450ROG

All tasks covered in this guide can be performed by an authorized field technician without jeopardizing the notebooks warranty.

Identifying the notebook modelCaution

It is important that you use the correctservice guide for the notebook. Failure to

follow the approved tasks for thenotebook model may result in damage to

the notebook.

The label on the bottom of the notebook contains information that identifies the notebook model and its features.

Use this chart to identify the main components of the notebook. For a complete list of replaceable parts, see Contents on page i.

System board(see page 80)3

Replacing Gateway Notebook Components www.gateway.comPreparing your work spaceBefore 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 components screws in their own section of a parts

sorter. Place each components 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.4

Preventing static electricity dischargewww.gateway.comPreventing static electricity dischargeWarning

To avoid exposure to dangerous electricalvoltages and moving parts, turn off your

notebook, remove the batteries, andunplug the power cord, modem cable,and network cable before opening the

case.

WarningTo prevent risk of electric shock, do not

insert any object into the vent holes of thenotebook.

ImportantBefore performing maintenance on the

notebook, you should read andunderstand the information in this

section.

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.

TapeSome of the procedures in this guide involve removing tape that holds cables 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 tape5
