1: Introduction

Overview

This manual covers the information you need to service or upgrade the notebook computer. Information about operating
the computer (e.g. getting started, and the Setup utility) is in the User’s Manual. Information about drivers (e.g. VGA &
audio) is also found in User’s Manual. That manual is shipped with the computer.

Operating systems (e.g. DOS, Windows 9x, Windows 2000, Windows XP, etc.) have their own manuals as do application
software (e.g. word processing and database programs). If you have questions about those programs, you should consult
those manuals.

The notebook computer is designed to be upgradeable. See “Disassembly” on page 2 - 1 for a detailed description of the
upgrade procedures for each specific component. Please note the warning and safety information indicated by the “”
symbol.

The balance of this chapter reviews the computer’s technical specifications and features.

2: Disassembly

Overview

This chapter provides step-by-step instructions for disassembling parts and subsystems. When it comes to reassembly,
reverse the procedures (unless otherwise indicated).

We suggest you completely review any procedure before you take the computer apart.

Disassembly

Procedures such as upgrading/replacing the RAM, CD device and hard disk are included in the User’s Manual but are
repeated here for your convenience.

To make the disassembly process easier each section may have a box in the page margin. Information contained under
the figure # will give a synopsis of the sequence of procedures involved in the disassembly procedure. A box with a 
lists the relevant parts you will have after the disassembly process is complete. Note: The parts listed will be for the dis­assembly procedure listed ONLY, and not any previous disassembly step(s) required. Refer to the part list for the previ­ous disassembly procedure. The amount of screws you should be left with will be listed here also.

A box with a  will provide any possible helpful information. A box with a  contains warnings.

An example of these types of boxes are shown in the sidebar.

Overview 2 - 1

Disassembly

2.Disassembly

NOTE: All disassembly procedures assume that the system is turned OFF, and disconnected from any power supply (the
battery is removed too).

Maintenance Tools

The following tools are recommended when working on the notebook PC:

• M3 Philips-head screwdriver

• M2.5 Philips-head screwdriver (magnetized)

• M2 Philips-head screwdriver

• Small flat-head screwdriver

• Pair of needle-nose pliers

• Anti-static wrist-strap

Connections

Connections within the computer are one of four types:

Locking collar sockets for ribbon connectors To release these connectors, use a small flat-head screwdriver to

gently pry the locking collar away from its base. When replac­ing the connection, make sure the connector is oriented in the
same way. The pin1 side is usually not indicated.

2 - 2 Overview

Pressure sockets for multi-wire connectors To release this connector type, grasp it at its head and gently

rock it from side to side as you pull it out. Do not pull on the
wires themselves. When replacing the connection, do not try to
force it. The socket only fits one way.

Pressure sockets for ribbon connectors To release these connectors, use a small pair of needle-nose pli-

ers to gently lift the connector away from its socket. When re­placing the connection, make sure the connector is oriented in
the same way. The pin1 side is usually not indicated.

Board-to-board or multi-pin sockets To separate the boards, gently rock them from side to side as

you pull them apart. If the connection is very tight, use a small
flat-head screwdriver - use just enough force to start.

Maintenance Precautions

The following precautions are a reminder. To avoid personal injury or damage to the computer while performing a re­moval and/or replacement job, take the following precautions:

1. Don't drop it. Perform your repairs and/or upgrades on a stable surface. If the computer falls, the case and other
components could be damaged.

2. Don't overheat it. Note the proximity of any heating elements. Keep the computer out of direct sunlight.

3. Avoid interference. Note the proximity of any high capacity transformers, electric motors, and other strong mag-
netic fields. These can hinder proper performance and damage components and/or data. You should also monitor
the position of magnetized tools (i.e. screwdrivers).

4. Keep it dry. This is an electrical appliance. If water or any other liquid gets into it, the computer could be badly dam-
aged.

5. Be careful with power. Avoid accidental shocks, discharges or explosions.

• Before removing or servicing any part from the computer, turn the computer off and detach any power supplies.

• When you want to unplug the power cord or any cable/wire, be sure to disconnect it by the plug head. Do not pull on the
wire.

6. Peripherals – Turn off and detach any peripherals.

7. Beware of static discharge. ICs, such as the CPU and main support chips, are vulnerable to static electricity.
Before handling any part in the computer, discharge any static electricity inside the computer. When handling a
printed circuit board, do not use gloves or other materials which allow static electricity buildup. We suggest that you
use an anti-static wrist strap instead.

8. Beware of corrosion. As you perform your job, avoid touching any connector leads. Even the cleanest hands pro­duce oils which can attract corrosive elements.

9. Keep your work environment clean. Tobacco smoke, dust or other air-born particulate matter is often attracted to
charged surfaces, reducing performance.

10.Keep track of the components. When removing or replacing any part, be careful not to leave small parts, such as
screws, loose inside the computer.

Power Safety

Warning

Before you undertake
any upgrade proce­dures, make sure that
you have turned off the
power, and discon­nected all peripherals
and cables (including
telephone lines). It is
advisable to also re­move your battery in
order to prevent acci­dentally turning the
machine on.

2.Disassembly

Cleaning

Do not apply cleaner directly to the computer, use a soft clean cloth.
Do not use volatile (petroleum distillates) or abrasive cleaners on any part of the computer.
