Connections within the computer are one of four types:
Locking collar sockets for ribbon connectorsTo 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 - 2 Overview
Pressure sockets for multi-wire connectorsTo 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 connectorsTo 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 socketsTo 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).
Removal Warning
When removing any
cover(s) and screw(s)
for the purposes of device upgrade, remember
to replace the cover(s)
and screw(s) before
turning the computer 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
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 pu ll on the wir e.
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 component s. When removing or re placing any part, be careful not to leave small p arts, 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.

The computer may be mounted on a wall for display, however in order to avoid personal injury or damage to the computer
make note of the standards, warnings and precautions listed in this chapter:
The system meets VESA MIS-D Standard (100mm * 100mm), however before attaching any display bracket it is necessary to remove the stand.

Warning
If non-qualified installers are used to install any mounting system the system may fall and cause a serious injury if:
The wall bracket does not support the weight of the system.
The wall bracket is not securely (or is unevenly) fastened to the wall.
The wall itself is not sturdy enough to support the system.
An earthquake occurs.
This computer complies to the VESA MIS-D 100mm * 100mm standard. Make sure that any mounting system you want
to use meets the same standard.
It is imperative that you consult appropriate professional installers (i.e. qualified engineering, construction or architectural personnel) to install, move or service any mounting system. This is especially so as vertical surfaces vary widely
and thus the actual mounting of any screen is beyond the scope of what can be outlined in written manual form. Some
surfaces require significant reinforcement before any mount and display can function safely. Professional installers can
determine if any vertical surface can bear the weight of the whole system.

General Guidelines for Wall Mounting
•Only use professional installers to install, move or service any mounting system.
•The system must only be mounted on a wall which can support the whole system’s weight (including the weight of any
arm or bracket).
•Make sure any wall is perpendicular and flat.
•Any mounting system used must support a minimum of 30kg weight and be VESA compliant.
•Only use the screws and fittings supplied with the mounting system.
•Only use M4 screwsof a length of 12mm to attach any bracket to the computer.
•Drill any holes to a depth of 30mm (minimum), and on ly use the screws supplied with any bracket to attach it to the wall.
•Bear in mind that sufficient space must be left between the rear of the computer and the wall in order to allow:
access to the ports & jacks
the screen to be tilted (if the mounting system supports this)
ventilation space
•It usually requires two people to mount the display on the wall (i.e. when joining the display bracket to the wall bracket).
C. Wall Mounting Info
C - 4 Mounting Systems
•Make sure that any cables are firmly secured and do not cause an obstruction.
•Do not make any alterations or adjustments to any wall bracket yourself.
•Do not hang anything from (or add any other items to) the system.
•Do not expose the system to moisture or liquid.
•Do not mount the system in a location where it may excessively protrude or cause an obstruction.
•Do not mount the system too close to an air conditioning unit.
•Take care, and do not lean your weight on the system when cleaning it.
•Keep flammable objects and/or open flames away from the mounted system.
•Do not spill or spray liquid on the system.

The following pictures show some examples of how a system can be mounted on to a wall. These pictures are intended
for guideline purposes only, and are not specific instructions. Professional installers will determine the exact installation
procedure for your specific bracket and mounting conditions.
Installation Example
1.After removing the stand, the display bracket (which must to be VESA 100mm * 100mm compliant - weight rating
of 30kg minimum) is attached firmly to the rear of the computer using M4 screws (of a length of 12mm) provided
with the bracket.
Wall Mounting Info
C. Wall Mounting Info
2.The (VESA compliant) wall bracket can then be attached to the wall using the screws provided with the system
(holes in the flat, perpendicular wall should be drilled to a minimum depth of 30mm).

Rotation
Once mounted the screen may
be rotated through 180 degrees
up/down and left/right, and
through 270 degrees clockwise/
counterclockwise.
3.The display can now be mounted by lowering the display bracket (in this example) over the wall bracket and
attaching the screws. Note that this procedure usually requires two people, as one person will need to hold the
computer while the other inserts and tightens the screws.
4.The cables may now be attached, and firmly secured, to the system’s ports and jacks.
