Overview

This manual covers the information you need to service or upgrade the LV22C/LV22N/LV19C/LV19N 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. Windows XP, Windows Vista, 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 LV22C/LV22N/LV19C/LV19N 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.

2 - 2 Overview

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.

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 mag-
netic 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.

9. Insert the new module. The module will only fit one way as defined by the pin alignment.

10. 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.

11. Reverse the procedures to put the computer back together (don’t forget to reconnect the fan cable), and do not
forget all the screws. When you restart the computer the new memory configuration should be registered.

12. 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.
