Disassembly

2.Disassembly

NOTE: All disassembly procedures assume that the system is turned OFF, and disconnected from any power supply (the battery is removed too).

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

Pair of needle-nose pliers

Anti-static wrist-strap

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.
