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 7 mm Phillips.
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.

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.
