Hi, bit late in replying to this but have just come across it. What can happen is that the batteries age and swell up slightly putting pressure on to the underside of the trackpad, so affecting the click ability. The batteries tend start to fail after about three years. They're glued in so difficult to change unfortunately.

Definitely unscrew and remove the two screws that hold the MagSafe 2 connector then remove the connector with the board.

The connector that’s not mentioned in the dissasembly manual is the right hand loudspeaker connector. It pulls up, just the same way as the left hand loudspeaker connector does. No locking tab.

Other than that it’s a brilliant dissasembly instruction manual, well done.

I took the logic board out, re-soldered U8900 (well known issue with these boards) and put it back together following the manual in reveres. All works fine now.

One thing that I did which helped. I printed the manual off, then stuck the screws in every case to the page next to where each screw was described using cellotape. So every screw went back exactly where it came from.
