1: Introduction
Overview
This manual covers the information you need to service or upgrade the L295N/L297N 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 L295N/L297N 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
Information and
Component Parts
Warning
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.
Disassembly
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 dis-
assembly 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.
2.Disassembly
Overview 2 - 1
Disassembly
2.Disassembly
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.
2-2Overview
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
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.
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
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 mag-
4. Keep it dry. This is an electrical appliance. If water or any other liquid gets into it, the computer could be badly
5. Be careful with power. Avoid accidental shocks, discharges or explosions.
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.
8. Beware of corrosion. As you perform your job, avoid touching any connector leads. Even the cleanest hands pro-

2.Disassembly
•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.
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.

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.

2. The memory sockets will be visible at point on the mainboard.
3. For each module you want to replace, gently push the latches and toward the sides of the socket to release the
module. Push the latches to release the second module if necessary.
4. The module will pop-up, and you can remove it.
5. Insert the new module. The module will only fit one way as defined by the pin alignment.
6. Make sure the module is seated as far into the slot as it will go (DO NOT FORCE IT). The latches will click into
place on the sides of the module. Make sure they are secure.
7. Reverse the procedures to put the computer back together, and do not forget all the screws. When you restart the
computer the new memory configuration should be registered.
8. If the system doesn’t properly detect the new memory, and you are sure they are properly “seated”, you may
need to run the Setup utility.
