1INTRODUCTION
This manual covers the information you need to service or upgrade the LP200SC/ST LCD PC. 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 2, “Disassembly,” for a detailed description of the upgrade procedures for each specific component. In addition, the BIOS
can be updated using software.
This chapter briefly introduces the computer’s technical specifications, external features and system board features.

DISASSEMBLY
2DISASSEMBLY
This chapter provides step-by-step instructions for disassembling parts and subsystems. When it comes to reassembly, reverse the
procedures (unless otherwise indicated).
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 re-
placement procedure. Please pay attention to the component-specific upgrade notes.
Illustrations:
To enhance procedural clarity, the illustrations in this chapter do not include all components. Mylar insulation and
adhesive attachments are not shown unless they are critical to the disassembly process.
