What you need

  1. MacBook Pro 17" Models A1151 A1212 A1229 and A1261 Logic Board Replacement, Battery: step 1, image 1 of 1

    • Use your fingers to push both battery release tabs away from the battery and lift the battery out of the computer.

  2. MacBook Pro 17" Models A1151 A1212 A1229 and A1261 Logic Board Replacement, RAM Shield: step 2, image 1 of 1

    • Remove the four identical Phillips 3.4 mm screws from the memory door. These screws have 4 mm diameter heads rather than the 3 mm heads on the body screws.

    Edit

  3. MacBook Pro 17" Models A1151 A1212 A1229 and A1261 Logic Board Replacement: step 3, image 1 of 1

    • Lift the memory door up enough to get a grip on it, and slide it toward you, pulling it away from the casing.

    • Remove the three Phillips screws in the battery compartment near the latch. Apple was nice enough to tilt these screws at a slight angle to make them easier to remove. On the A1261 these screws have 4 mm diameter heads rather than the 3 mm heads on the body screws.

    • Release the tabs on each side of the RAM chip at the same time. These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

    • Pull the chip directly out from its connector.

    • If there are two RAM chips installed, repeat the above procedure for the second chip.

    • Disconnect the multi-colored battery connector from the logic board.

    • To properly reassemble your MacBook Pro, you'll have to clean off and replace the thermal compound from the three chips shown here. Use our Applying Thermal Paste Guide to prepare the processor and heat sink surfaces.

I haven't tried this (yet). However, one note that might be useful:

Note the heat sink compound on the tops of the CPU, video chip, and whatever the third chip is. You're going to need to clean that off the chips and the mating surface and carefully replace it with new compound. Mac's run hot, so it's important to do this carefully (for better heat conduction.

Buy a good quality thermal grease like "Arctic Silver" or "OCZ Freeze Extreme" (my favorite because its almost as good and easier to use). The instructions assume that you're putting the heat sink down on the CPU, but here you're putting the CPU down on the heat sink, so adjust accordingly.

Tried that. Rather helpful, but a few suggestions.

Step 18: I would suggest to avoid losen the screws that that fasten the heatsink to the board - unless your intention is to really replace the board or the thermal paste. It is possible to get the board in and out with the heatsink attached, but you may have to remove the fans first. Do not losen the five srews marked red towards the back.

Step 19: the mentioned coloured cable is not always coloured (it is not in my model), do not mistake that cable with the cable to the battery, which is also couloured and also connected to the bottom of the board. It may also be better to remove the left speaker assembly and the WLan card to get to the other end of that cable and disconnect it there.

If I Buy The Whole Logic Board Why Would I Have To Apply Thermal Compound To The Three Chips? The Logic Board Come With It Already Attached Right?? (17" Macbook Pro Model # A1229 Santa Rosa 2.6GHz) Or Did I Missed Something?

Pete - Reply

Would it be possible to replace the logic board of an A1212 with the logic board of an A1261?

Look at Step 14, the connectors seem to be different, at least at first sight. Why do you want to take that risk, by the way?
