Components

Replacing Gateway 450RGH Components

The 450RGH notebook has a standard configuration, which does not include either the EZ Point pointing device or the fingerprint reader. In addition to the standard configuration, there are three optional configurations. Option 1 includes the standard configuration plus the EZ Point pointing device only. Option 2 includes the standard configuration plus the fingerprint reader only. Option 3 includes the standard configuration plus both the EZ Point pointing device and the fingerprint reader.

This service guide includes procedures for the pointing device and the fingerprint reader.

Important This service guide is intended to be used only by an authorized

service provider. It is not intended for individual users or consumers.

Use this service guide to help plan your maintenance tasks for the Gateway 450RGH notebook. All tasks covered in this guide can be performed by an authorized field technician without jeopardizing the notebook’s warranty.

For information on the notebook’s general maintenance, technical support, safety notices, and regulatory notices, see the Gateway user’s guide.

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 the notebook are extremely sensitive to static electricity, also known as electrostatic discharge (ESD).

Warning To avoid exposure to dangerous electrical voltages and

moving parts, turn off the notebook and unplug the power cord and modem and network cables before opening the case.

Caution ESD can permanently damage electrostatic

discharge-sensitive components in the notebook. Prevent ESD damage by following ESD guidelines every time you open the notebook case.

Before replacing components, follow these guidelines:

■ Turn off the notebook.

■ 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.

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

into the vent holes of the notebook.

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

■ Unplug the power cord and the modem and network cables.

■ Remove the main battery. For more information, see “Removing the main battery”

on page 8.

■ Disconnect all peripheral devices and remove any PC Cards.

Before working with notebook 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.

■ Always hold components by their edges. Avoid touching the edge connectors. Never

slide components over any surface.

Preparing the notebook

Warning To avoid exposure to dangerous electrical voltages and

moving parts, turn off the notebook, remove the main and optional secondary batteries, and unplug the power cord and modem and network cables before opening the case. Replace the cover before you restore power or reconnect the modem and network cables.

To prepare the notebook for maintenance:

■ Follow all ESD recommendations.

■ Make sure that the modular drive is empty.

■ Disconnect all peripheral devices and remove any PC Cards.

■ Turn off the notebook and unplug the power cord and modem and network cables

(if attached).

Replacing the modular bay component

The modular bay on the notebook is hot-swappable and holds one of the following components:

■ CD drive

■ DVD drive

■ Memory card reader

■ Secondary battery

To determine the type of drive in a bay, examine the logo on drive tray’s plastic cover. The logo identifies the drive in the modular bay.

To remove the modular bay component:

1 If a drive module is in the bay, make sure that the drive is empty. 2 Turn the notebook over so the bottom is facing up. 3 Slide and hold the modular bay latch closest to the back of the notebook. 4 Slide the other modular bay release latch. The component moves out slightly.

Replacing the IEEE 802.11 Mini PCI card

Caution By law, only approved wireless modules provided by

Gateway, or a Gateway authorized representative, explicitly for the Gateway 450RGH may be installed in this notebook.

Caution Legal requirements dictate that a security screw (or other

means) be used to attach the mini-PCI cover to the chassis in a manner that restricts end user access. End users are strictly prohibited from having access to the wireless card. Due to manufacturing process changes, Gateway 450RGH notebooks manufactured after August 7, 2003 require a Torx head security screw to attach the mini-PCI cover.

Caution Legal requirements dictate the mini-PCI cover be in place

during any and all operation of the notebook’s wireless feature.

Tools you need to complete this task:

Torx T8 screwdriver

To replace the IEEE 802.11 Mini PCI card:

1 Disconnect the AC adapter, modem and network cables, then prepare the notebook

by following the instructions in “Preparing the notebook” on page 7.

2 Turn the notebook over so the bottom is facing up. 3 Remove the main battery by following the instructions in “Removing the main

battery” on page 8.

4 If the modular bay contains the secondary battery, remove the secondary battery

by following the instructions in “Replacing the modular bay component” on

page 10.

5 Loosen the captive Torx screw that secures the mini PCI cover. (The screw cannot

be removed.)
