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 speci-
fied.
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 reassem-
bly, 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 replace-
ment procedure. Please pay attention to the component-specific upgrade notes.

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.
