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.
