    • Whenever working near the logic board, it is always wise to first disconnect the battery to avoid short circuits.

    • If present, grab the plastic tab attached to the battery connector and pull it toward the front edge of the device. For Late-2011 models the battery connector will not have a tab and is simply a plug that inserts straight down into the motherboard--to remove pry the plug straight up.

    • If the plastic tab is missing, use a spudger to pry the connector up from its socket.

    • Pull the tab parallel to the face of the logic board.

    • Use the flat end of a spudger to lift the right fan connector out of its socket on 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.

    • If the heat sink appears to be stuck to the logic board after removing all eight screws, it may be helpful to use a spudger to separate the two components.

    • If you need to mount the heat sink back onto the logic board, we have a thermal paste guide that makes replacing the thermal compound easy.

After compleating this repair , my mac had the normal hard drive noise then a chime did not even grey screen . almost instantly I smelt fire and saw smoke pouring out of the case.. maac was on battery at the time .. I opened it up and disconected the battery and then I saw the video display cable (Step 21 ) it had glowing embers on the tape and tottally melted one side of it ... the connector to the logic board has black marks , but i do not know if the damage is extened to the logic board or if I can get away with a new dispay data cable , dont even know where to source one here in NZ .. any help would be great

I completed this guide. When I finished the macbook would not turn on => PANIC

I went over and the problem was the keyboard cable. The Step 17 is a little difficult in reverse. Pay special atention at the correct position of the keyboard ribbon cable.

It was a little scare. Otherwise all perfect! Thank you very much!

Successfully changed the thermal paste by following this guide. My MacBook Pro had some issues after I put it back together because of loose and improperly seated cables. In my case, the display cable wasn't seated properly and the IR-sensor cable was loose. So if your machine doesn't turn on, or something seems to be working incorrectly, it's definitely worth double checking the cables.

did changing the thermal paste lower your temps? what was it before, what is it now? thanks for sharing.

B S -

Yes B S, the temps will be lower. Apple is known to put only a tiny amount or bad quality thermal paste on their machines, so even is a Mac is brand new, temperatures will be better if the thermal paste is replaced. I have replaced thermal paste on numerous computers and have never regretted it :)
