FCC Statement
(Federal Communications Commission)
You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installa-
tion. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
• Re orient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the service representative or an experienced radio/TV technician for help.
Operation is subject to the following two conditions:
1. This device may not cause interference.
And
2. This device must accept any interference, including interference that may cause undesired operation of the device.

Preface
FCC RF Radiation Exposure Statement:
1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
2. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment
should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body.
IMPORTANT SAFETY INSTRUCTIONS
Follow basic safety precautions, including those listed below, to reduce the risk of fire, electric shock, and injury to persons
when using any electrical equipment:
1. Do not use this product near water, for example near a bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement or
near a swimming pool.
2. Avoid using this equipment with a telephone line (other than a cordless type) during an electrical storm. There may be a
remote risk of electrical shock from lightning.
3. Do not use the telephone to report a gas leak in the vicinity of the leak.
4. Use only the power cord and batteries indicated in this manual. Do not dispose of batteries in a fire. They may explode. Check
with local codes for possible special disposal instructions.
5. This product is intended to be supplied by a Listed Power Unit (Full Range AC/DC Adapter – AC Input 100 - 240V, 50 - 60Hz,
DC Output 19V, 6.3A).
CAUTION
This Computer’s Optical Device is a Laser Class 1 Product

Warning
Use only shielded cables to connect I/O devices to this equipment. You are cautioned that changes or modifications not ex-
pressly approved by the manufacturer for compliance with the above standards could void your authority to operate the
equipment.

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.
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.
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.

Removal Warning
When removing any
cover(s) and screw(s)
for the purposes of de-
vice upgrade, remem-
ber to replace the
cover(s) and screw(s)
before restoring power
to the system.
Also note the following
when the cover is re-
moved:
• Hazardous mov-
ing parts.
• Keep away from
moving fan blades
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 and
power cord). You must
also remove your bat-
tery in order to prevent
accidentally turning the
machine on.

Preface

Preface
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.
Servicing
Do not attempt to service the computer yourself. Doing so may violate your warranty and expose you and the computer to
electric shock. Refer all servicing to authorized service personnel. Unplug the computer from the power supply. Then refer
servicing to qualified service personnel under any of the following conditions:
• When the power cord is damaged or frayed.
• If the computer has been exposed to any liquids.
• If the computer does not work normally when you follow the operating instructions.
• If the computer has been dropped or damaged (do not touch the poisonous liquid if the LCD panel breaks).
• If there is an unusual odor, heat or smoke coming from your computer.

Removal Warning
When removing any cover(s) and screw(s) for the purposes of device upgrade, remember to replace the cover(s) and
screw(s) before turning the computer on.

VGA & audio) is also found in User’s Manual. That manual is shipped with the computer.
Operating systems (e.g. Windows 7, 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 A110EU series computer is designed to be upgradeable. See Disassembly 2 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

1 - 4 Tilting the LCD Screen & Adjusting the Height
1.Introduction
Tilting the LCD Screen & Adjusting the Height
It is possible to tilt the LCD screen in order to get the best
possible viewing angle of the screen without glare etc.
• Place one hand at the top of the computer , and use the
other to open the stand to an angle of around 15
degrees from the vertical position (the stand will allow
you to adjust to the appropriate angle if you pull it out and
let it spring back).
• Apply pressure with one hand at the top (at point ) of
the computer (while holding on to the side with the other
hand) to carefully push the LCD screen down in order to
tilt it to the appropriate viewing angle (up to 50 degrees
from the vertical position).
• Use one hand at the top of the computer (while holding on
to the side with the other hand) to move the computer back
to the original position


Moving the
Computer
We strongly recom-
mend using both hands
to move the computer.
You can use one hand
to grip the computer by
the stand, and the oth-
er to hold the top of the
LCD screen.
It is recommended that
you carry the computer
with the LCD facing
your body to avoid
scratching the surface
against other objects.
However take care not
to scratch the LCD with
any personal items,
belt fittings or jewelry
etc.(one hand gripping
the stand and the other
gripping the top of the
computer to avoid acci-
dentally dropping it).
