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 connec-
tor away from its socket. When replacing the connection, make sure the connector is ori-
ented 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
the separation.
