1: Introduction
Overview
This manual covers the information you need to service or upgrade the L295P/L297P 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. DOS, Windows 9x, Windows NT 4.0, Windows 2000, Windows XP, OS/2 Warp, UNIX, 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 L295P/L297P LCD computer 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.

2: Disassembly
Overview
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.
Procedures such as upgrading/replacing the RAM, CD device and hard disk are included in the User’s Manual but are
repeated here for your convenience.
To make the disassembly process easier each section may have a box in the page margin. Information contained under
the figure # will give a synopsis of the sequence of procedures involved in the disassembly procedure. A box with a �
lists the relevant parts you will have after the disassembly process is complete. Note: The parts listed will be for the disassembly
procedure listed ONLY, and not any previous disassembly step(s) required. Refer to the part list for the previous
disassembly procedure. The amount of screws you should be left with will be listed here also.
A box with a � will provide any possible helpful information. A box with a � contains warnings.
An example of these types of boxes are shown in the sidebar.

Disassembly
2 - 2 Overview
NOTE: All disassembly procedures assume that the system is turned OFF, and disconnected from any power supply,
and that all peripheral cables are disconnected (including telephone lines and network cables).
Maintenance Tools
The following tools are recommended when working on the computer:
• 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
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.

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.
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.

Power Safety
Warning
Before you undertake
any upgrade procedures,
make sure that
you have turned off
the power, and disconnected
all peripherals
and cables
(including telephone
lines). It is advisable
to also remove your
battery in order to prevent
accidentally turning
the machine on.

Appendix A: Part Lists
This appendix breaks down the computer’s construction into a series of illustrations. The component part numbers are
indicated in the tables opposite the drawings.
Note: This section indicates the manufacturer’s part numbers. Your organization may use a different system, so be sure
to cross-check any relevant documentation.
Note: Some assemblies may have parts in common (especially screws). However, the part lists DO NOT indicate the
total number of duplicated parts used.
Note: Be sure to check any update notices. The parts shown in these illustrations are appropriate for the system at the
time of publication. Over the product life, some parts may be improved or re-configured, resulting in new part numbers.

Appendix C: Clock Ratios
This appendix is about the system’s clock ratios.
The table below lists the supported memory clock ratios. AGP, CSA and HI run at 66 MHz common clock and are asynchronous
to the chipset core. There is no required skew or ratio between FSB/Chipset and 66MHz system clocks.
System Memory Clock Ratios
Host Clock DRAM Clock Ratios DRAM Data Rate DRAM Type Peak Bandwidth
100 MHz 133 MHz 3/4 266 MT/s DDR-DRAM 2.1 GB/s
