1 INTRODUCTION
OVERVIEW
This manual covers the information you need to service or upgrade both the LP200C and LP200T LCD PCs. The two
models mainly differ in appearance. All the description in this manual applies to both models unless otherwise specified.
Information about operating the computer (e.g. getting started, and the System Configuration Utility) is in the User’s
Manual. Information about drivers (e.g. VGA & audio) is also found in the User’s Manual. That manual is shipped
with the computer.
Operating systems (e.g. Windows 98 Second Edition, Windows 2000 Professional, 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 LCD PC comes with a built-in 15” LCD display and is upgradeable in the areas of CPU, system memory and hard
disk. See Chapter 3, “Disassembly,” for a detailed description of the upgrade procedure for each specific component.
This chapter briefly introduces the computer’s technical specifications, external features and system board features.

OVERVIEW
This chapter provides step-by-step instructions for disassembling parts and subsystems. When it comes to reassembly, reverse the procedures (unless otherwise indicated). All the procedures apply to both the LP200C and LP200T
unless otherwise specified.
We suggest you completely review any procedure before you take the computer apart.
CPU and Memory Upgrades:
The upgrade procedures for CPU and system memory involve more than the component-specific removal and replacement procedure. Please pay attention to the component-specific upgrade notes.

2. DISASSEMBLY
MAINTENANCE TOOLS
The following tools are recommended when working on the LCD 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
* note Maintenance Precaution #3.
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 replacing 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 pliers to gently lift the
connector away from its socket. When replacing 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 the separation.

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 magnetic 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.
C
LEANING
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.
Maintenance Precautions
BACK COVER REMOVAL
1. Place the system with its LCD display facing down.
2. Remove 5 screws (A, , B, C, D & E) which secure the Back Cover to the rest of the system.

Upgrade Notes on the next page.
1. Unplug the Fan Cable from Connector CN5.
2. Disengage both caches at the sides of the Fan from the CPU socket.
3. A thermal pad is attached to the Fan. Remove the Fan with the Thermal Pad from the CPU.
4. Disengage the CPU lever and remove the CPU.
FNote for Replacing the CPU: : Reverse the removal procedure. Please also note the following:
When inserting the CPU, put the CPU in the CPU socket with the notched corner of the CPU aligning with the notched
corner of the CPU socket and then engage the lever.

INSTALLING DIMMS
1. Insert a DIMM in either slot at about a 20
o
angle. Grooves on the sides of the module
allow you to insert it only one way. Make sure
it is seated as far into the slot as it will go.
DO NOT FORCE IT. The module should fit in
without much pressure. If there is a lot of
resistance, check to make sure the DIMM is
properly seated.
2. Click in the slot levers to secure the module.
3. Reinstall the back cover.

FMemory Upgrade Note:
• If you have changed the memory configuration, run SCU so the new total can be registered in the CMOS.
• If you have increased memory, check to see if you need to recreate the Hibernate-specific file if the system
runs Windows 98 SE with Hibernate support enabled. (Refer to
