Preface

Instructions for Care and Operation

The notebook computer is quite rugged, but it can be damaged. To prevent this, follow these suggestions:

1. Don’t drop it, or expose it to shock. If the computer falls, the case and the components could be damaged.

2. Keep it dry, and don’t overheat it. Keep the computer and power supply away from any kind of heating element. This

is an electrical appliance. If water or any other liquid gets into it, the computer could be badly damaged.

3. Follow the proper working procedures for the computer. Shut the computer down properly and don’t forget to save

your work. Remember to periodically save your data as data may be lost if the battery is depleted.

Do not expose the computer

to any shock or vibration. Do not place it on an unstable

surface. Do not place anything heavy

on the computer.

Do not expose it to excessive

heat or direct sunlight. Do not leave it in a place

where foreign matter or mois-

ture may affect the system.

Don’t use or store the com-

puter in a humid environment. Do not place the computer on

any surface which will block

the vents.

Do not turn off the power

until you properly shut down

all programs.

Do not turn off any peripheral

devices when the computer is

on.

Do not disassemble the com-

puter by yourself. Perform routine maintenance

on your computer.

Preface

4. Avoid interference. Keep the computer away from high capacity transformers, electric motors, and other strong mag-

netic fields. These can hinder proper performance and damage your data.

5. Take care when using peripheral devices.

Power Safety

The computer has specific power requirements:

• Only use a power adapter approved for use with this computer.

• Your AC adapter may be designed for international travel but it still requires a steady, uninterrupted power supply. If you are

unsure of your local power specifications, consult your service representative or local power company.

• The power adapter may have either a 2-prong or a 3-prong grounded plug. The third prong is an important safety feature; do

not defeat its purpose. If you do not have access to a compatible outlet, have a qualified electrician install one.

• When you want to unplug the power cord, be sure to disconnect it by the plug head, not by its wire.

• Make sure the socket and any extension cord(s) you use can support the total current load of all the connected devices.

• Before cleaning the computer, make sure it is disconnected from any external power supplies.

Use only approved brands of

peripherals. Unplug the power cord before

attaching peripheral devices.

Do not plug in the power

cord if you are wet. Do not use the power cord if

it is broken. Do not place heavy objects

on the power cord.



Power Safety

Warning

Before you undertake

any upgrade proce-

dures, make sure that

you have turned off the

power, and discon-

nected all peripherals

and cables (including

telephone lines). It is

advisable to also re-

move your battery in

order to prevent acci-

dentally turning the

machine on.

Battery Precautions

• Only use batteries designed for this computer. The wrong battery type may explode, leak or damage the computer.

• Do not remove any batteries from the computer while it is powered on.

• Do not continue to use a battery that has been dropped, or that appears damaged (e.g. bent or twisted) in any way. Even if the

computer continues to work with a damaged battery in place, it may cause circuit damage, which may possibly result in fire.

• Recharge the batteries using the notebook’s system. Incorrect recharging may make the battery explode.

• Do not try to repair a battery pack. Refer any battery pack repair or replacement to your service representative or qualified service

personnel.

• Keep children away from, and promptly dispose of a damaged battery. Always dispose of batteries carefully. Batteries may explode

or leak if exposed to fire, or improperly handled or discarded.

• Keep the battery away from metal appliances.

• Affix tape to the battery contacts before disposing of the battery.

• Do not touch the battery contacts with your hands or metal objects.



Battery Disposal

The product that you have purchased contains a rechargeable battery. The battery is recyclable. At the end of

its useful life, under various state and local laws, it may be illegal to dispose of this battery into the municipal

waste stream. Check with your local solid waste officials for details in your area for recycling options or proper

disposal.

Caution

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommend-

ed by the manufacturer. Discard used battery according to the manufacturer’s instructions.

2.Disassembly

Chapter 2: Disassembly

Overview

This chapter provides step-by-step instructions for disassembling the M740J/M740JU/M760J/M760JU series note-

book’s 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.

Procedures such as upgrading/replacing the RAM, optical 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 dis-

assembly procedure listed ONLY, and not any previous disassembly step(s) required. Refer to the part list for the previ-

ous disassembly procedure. The amount of screws you should be left with will be listed here also.

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

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

Disassembly

2 - 2 Overview

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 replac-

ing the connection, make sure the connector is oriented in the

same way. The pin1 side is usually not indicated.

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 re-

placing 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 re-

moval 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

damaged.

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 pro-

duce 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.

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.
