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.

Instructions for Care and Operation
The 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. Avoid interference. Keep the computer away from high capacity transformers, electric motors, and other strong magnetic
fields. These can hinder proper performance and damage your data.
4. 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.
5. Take care when using peripheral devices.

Preface
Power Safety
The computer has specific power requirements:
• 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.

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).

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.

Chapter 1: Introduction
Overview
This manual covers the information you need to service or upgrade the L390T series LCD computer. Information about
operating the computer (e.g. getting started, and the Setup utility) is in the User’s Manual. Information about drivers (e.g.
VGA & audio) is also found in User’s Manual. That manual is shipped with the computer.
Operating systems (e.g. Windows XP, Windows Vista, 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 L390T series notebook is designed to be upgradeable. See “Disassembly” 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
“” symbol.
The balance of this chapter reviews the computer’s technical specifications and features.

Moving the Computer
We strongly recommend using both hands to
move the computer. You can use one hand to
grip the computer by the stand, and the other 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 grip-
ping the stand and the other gripping the top of
the computer to avoid accidentally dropping it).
