Maintenance Tools
The following tools are recommended when working on the notebook PC:
•
M3 Philips-head screwdriver

M2.5 Philips-head screwdriver (magnetized)

M2 Philips-head screwdriver

Small flat-head screwdriver

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 replac-
ing 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 pli-
ers to gently lift the connector away from its socket. When re-
placing 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.
