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 - 2 Overview
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 pli-
ers 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 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 components. When removing or re placing any part, be careful not to leave small p arts, such as
screws, loose inside the computer.
