Disassembly

The disassembly procedures appear in the following order:

General Disassembly

• Keyboard and heat plate

• LCD module

• Top cover assembly

• Bottom cover assembly

Module Disassembly

• HDD module

All disassembly procedures assume that the system is turned OFF, and disconnected from any power supply

(the battery is removed too). We also assume that the CD device (CD-ROM/DVD-ROM/CD-RW) or the FDD

device (FDD/LS-120) is removed as well as the HDD. All of these procedures are described in the User’s

Manual which accompanies the system.

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

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 the separation.
