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.
Preface
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.
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.
Do not expose it to excessive
heat or direct sunlight.
Do not leave it in a place
where foreign matter or moisture may affect the system.
Don’t use or store the computer in a humid environment.
Do not place the computer on
any surface which will block
the vents.
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 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 computer by yourself.
Perform routine maintenance
on your computer.

4. Avoid interference. Keep the computer away from high capacity transformers, electric motors, and oth er strong mag-
netic fields. These can hinder proper performance and damage your data.
5. Take care when using peripheral devices.
Preface
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.
Use only approved brands of
peripherals.
Unplug the power cord befor e
attaching 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 stea dy, uninterrupted po wer supply. If you ar e
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.
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.
VI
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 Disposal
The product that you have purchased contains a rechargeab le battery. The battery is re cyclable. 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 i n your area fo r recycling options or p roper
disposal.

Chapter 2: Disassembly
Overview
This chapter provides step-by-step instructions for disassembling the TN70M/TN71M 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.
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 also provide any possible helpful information. A box with a contains warnings.
An example of these types of boxes are shown in the sidebar.
