2 EditStep 4 — Fan

Slightly lift the lower case and push it toward the

rear of the computer to free the mounting tabs.

For precautionary purposes, we advise

that you disconnect the battery connector

from the logic board to avoid any electrical

discharge. This step is optional and is not required.

Use the flat end of a spudger to lift the battery

connector up out of its socket on the logic board.

Use a spudger to pry the fan connector out of its

seat, and straight up off the logic board.

It is useful to twist the spudger axially

from beneath the fan cable wires to

release the connector.

The fan socket and the fan connector can

be seen in the second and third pictures.

Be careful not to break the plastic fan

socket off the logic board as you use your spudger

to lift the fan connector straight up and out of its

socket. The layout of the logic board shown in the

second picture may look slightly different than your

machine but the fan socket is the same.

One 5 mm Phillips.

Lift the display data cable bracket out of the upper

case.

Use the flat end of a spudger to pry the subwoofer

and right speaker connector up off the logic board.

In this step you will disconnect the camera

cable. Most machines will have a small self

adhesive plastic retainer stuck to the logic

board to keep the connector in place. Before

disconnecting the cable, be sure this retainer is

moved out of the way.

Pull the camera cable connector toward the optical

drive to disconnect it from the logic board.

This socket is metal and easily bent. Be

sure to align the connector with its socket

on the logic board before mating the two

pieces.

Remove the four 8.5 mm Phillips screws securing

A spring is held under each of these

screws.

Gently lift the heat sink off the logic board.

When you mount the heat sink back onto

the logic board, be sure to apply a new

layer of thermal paste. We have a guide

that makes replacing the thermal paste easy.

Comments

Disconnect the DC-In board by pulling its connector

away from the socket on the logic board.

Release the tabs on each side of the chip by

simultaneously pushing each tab away from the

RAM.

These tabs lock the chip in place and

releasing them will cause the chip to "pop"

up.

After the RAM chip has popped up, pull it straight

out of its socket.

Repeat this process if a second RAM chip

is installed.

Logic board remains.
