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.

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 before
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 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.

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.

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

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.

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
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 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.
