Disconnect the port hatch ribbon cable from the logic board by pulling it straight up by its black pull tab. Pull the audio out ribbon cable off the adhesive securing it to the upper case. Use a spudger to pry the audio out ribbon cable connector board off the hard drive bracket.

I skipped the step (6c) of prying the audio out ribbon cable connector board off the hard drive bracket (& disconnecting it), since it doesn't come off real easily, and I didn't want to damage it. It only requires a little more care when removing the HD from it's bracket if you skip step 6c.

This is not necessary and looks pretty risky too.

Agreed, I encountered no issues when I skipped this on a Rev.B model.

Reversing step 8 is where I ran into trouble. The replacement fan I had was slightly thicker than the original and caused the ZIF cable to work its way out of the tenuous connection it had to the SSD, resulting in a "?" missing boot drive error upon startup. Took me three tries to get it right! The difficulty is to get the drive connector to the logic board to reach and seat without pulling the other end out of the drive.

There is a cable glued to the diskframe that must be loosened with a spudger before you can remove the frame.

I have replaced several Logic boards at this point on the A1304 model, and realized that I did not need to remove the heatsink (Steps 14 through 17). You need to remove the screws around the fan, and disconnect the microphone cable (step 19). Of course if your replacement logic board doesn't include a heatsink, you need to take it off.

  • Lift the heat sink up off the logic board.

  • Be mindful of the microphone cable when lifting the heat sink, as it can get tangled on the top edge of the fan.

  • When you mount the heat sink back onto the logic board, be sure to apply a new layer of thermal paste. We have a guide that makes replacing the thermal paste easy.

I removed the fan at this point as well. Disconnect the small connector from the fan to the logic board and lift out the fan. Good time to blow off the dust!

I currently have a 1.6ghz A1237 Original Macbook Air, and I was wondering if the logicboard is interchangeable with the late 2008 model A1304. I hope someone can answer this for me. I want to swap out the logic board for A1304.
