Power Safety
Preface

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

Battery Precautions
· Only use batteries designed for this computer. The wrong battery type may explode, leak or damage the computer.
· 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 Guidelines
The following can also apply to any backup batteries you may have.

Preface
· If you do not use the battery for an extended period, then remove the battery from the computer for storage.
· Before removing the battery for storage charge it to 60% - 70%.
· Check stored batteries at least every 3 months and charge them to 60% - 70%.

Battery Disposal
The product that you have purchased contains a rechargeable battery. The battery is recyclable. At the end of its useful life, under var-
ious 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 recommended by the manufacturer.
Discard used battery according to the manufacturer's instructions.

Battery Level
Click the battery icon in the taskbar to see the current battery level and charge status. A battery that drops below a level of 10%
will not allow the computer to boot up. Make sure that any battery that drops below 10% is recharged within one week.

Disassembly

Chapter 2: Disassembly
Overview
This chapter provides step-by-step instructions for disassembling the W940TU series notebook'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.

2.Disassembly
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-
Information
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.

Warning

Overview 2 - 1
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
2.Disassembly

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.

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.
