Paso 1 — Logic Board ¶
Disconnect the 11 remaining cable connectors, removing tape as necessary.
Paso 2 ¶
Remove the following 9 Phillips screws from the logic board:
Three 6.5 mm in the upper left corner.
Six remaining 4.5 mm.
Paso 3 ¶
Lift up the left side of the logic board enough to disconnect the black and red power cable from the left side of the logic board.
While the logic board is lifted, also disconnect the battery connector.
Paso 4 ¶
Remove the single black Phillips screw from the top of the left speaker housing.
Remove the 4 mm hex nut from the left speaker housing.
Lift the left speaker housing from the lower case and disconnect the microphone/speaker connector.
Paso 5 ¶
Lift the left side of the logic board and disconnect the modem cable from the underside of the logic board. A spudger is useful for freeing the connector from its adhesive.
Paso 6 ¶
Very gently lift up the left side of the logic board.
Lift the left edge of the board up to approximately a 30 degree angle (if you don't have your protractor handy, just lift until the DVI port clears the right hinge).
Once the logic board clears the ports, slide it out to the left.
Paso 7 ¶
Use a firm plastic edge to scrape the thermal material off the heat sink.
Apply a new layer of thermal paste to the heat sink.
