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.
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.

Preparing your work space
www.gateway.com
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).
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.
■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.
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.
Warning To prevent risk of electric shock, do not insert any object
into the vent holes of the notebook.

Preparing the notebook
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.

(if attached).
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.

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

Adding or replacing memory modules
Tools you need to complete this task:
To add or replace memory modules:
1Disconnect the AC adapter, modem and network cables, then prepare the notebook
by following the instructions in “Preparing the notebook” on page 7.
2Turn the notebook over so the bottom is facing up.
3Remove the main battery by following the instructions in “Removing the main
battery” on page 8.
4If the modular bay contains the secondary battery, remove the secondary battery
by following the instructions in “Replacing the modular bay component” on
page 10.

8Pull the memory module out of the slot.
9Hold the new or replacement module at a 30-degree angle and press it into the empty
memory slot. This module is keyed so it can only be inserted in one direction. If
the module does not fit, make sure that the notch in the module lines up with the
tab in the memory slot.
10 Gently push the module down until it clicks in place.
11 Replace the memory bay cover and tighten the cover screw.
12 Replace the main battery and secondary battery (if installed). Connect the AC
adapter and modem and network cables, then turn on the notebook.

Replacing the IEEE 802.11 Mini PCI
card
Tools you need to complete this task:
To replace the IEEE 802.11 Mini PCI card:
1Disconnect the AC adapter, modem and network cables, then prepare the notebook
by following the instructions in “Preparing the notebook” on page 7.
2Turn the notebook over so the bottom is facing up.
3Remove the main battery by following the instructions in “Removing the main
battery” on page 8.
4If the modular bay contains the secondary battery, remove the secondary battery
by following the instructions in “Replacing the modular bay component” on
page 10.
5Loosen the captive Torx screw that secures the mini PCI cover. (The screw cannot
be removed.)
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.
