    • 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.

    • Use the flat end of a spudger to pry the subwoofer and right speaker connector up off the logic board.

  10. MacBook Pro 13" Unibody Mid 2009 Heat Sink Replacement: paso 10, imagen 1 de 1
    • 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.

After completing this process and reapplying thermal paste on my CPU and GPU, CPU Core 1 & 2 temperature sensors were not being read. As a result, my fan was not operating and the CPU diode temperature jumped to >100C.

To fix this I had to reset the SMC (System Management Controller). For this model it is done by holding done Shift+Control+Option and pressing the power button while the computer is off.

I have OS X 10.8.5 running. I also replaced my battery at the same time as reapplying thermal paste. No idea if that affected the temperature sensors.

Followed this guide to change thermal paste on CPU & GPU, all worked fine, now I have >10°C difference. I had a problem on a screw that wore out, solved by cutting a piece of motherboard. I recommend following this guide alongside a youtube guide video, if you are not sure on how to unplug some cables (like in which direction to pull). And as always, double (triple possibly) check that you have reconnected all cables, otherwise you’ll have to go through all of this again.

Well, my computer no longer turns on...reconnected all the cables, was very cautious and followed all steps and now it won't power on...it will charge, just won't power on anymore
