Image 1/2: An interposer is the name for an interface that links one electrical connection to another. In this repair, it is the board connecting the battery to logic board. Image 2/2: Lift the Interposer off the logic board and remove it.

    • Removing this board will ensure that the battery remains disconnected throughout your repair, preventing your computer from accidentally powering on. It's also a good idea to take it out so it doesn't fall out unexpectedly.

WHy to remove battery contact board? Replace can happen without it also, right.

when reinstalling the interposer - pay close attention to proper orientation. You can install it upside down and still make it fit - don't ask me how I know!

Hi,

found 4 rubber spacers on the 4 2,5mm screws

Also found the rubber caps on the 4x2.7mm - didn't bother to replace the caps and didn't have any problems with them.

  • Lift and remove the heat sink up off the logic board assembly.

  • When reinstalling the heat sink, be sure to apply a new layer of thermal paste. If you have never applied thermal paste before, we have a guide that makes it easy.

Hey! You skipped a step!

What about the cable (don't know what it does) that runs right across the fan, interfering with pulling the fan out.

It's still in place in Step 14, but here in Step 15 it's magically removed itself, and can be seen resting luxuriously on top of the Airport card.

How do we get that outta there?

Great tutorial. I would add two comments. Firstly between steps 14 and 15 there is a cable that needs to be unconnected (see other tutorials where it is detailed) - it needs to be "walked" out, and you ned to remember to reconnect this. Secondly when putting the logic board back in be sure not to trap any of the connectors underneath it. It is a real struggle! I ended up undoing the 6 screws that hold the main battery assembly in and lifting this slightly to give me space and allow me to reinsert the ribbon cables on that side of the board. The reason I needed to disassemble my laptop was that it kept going into sleep mode, sometimes every few seconds. Apple wanted to charge £550 to fix it. I found the problem was with the micro-switch that detects if the lid is closed (it would work fine in clamshell mode). Switch is between the thunder port and USB sockets. Sprayed with contact cleaner, isopropyl and antistatic spray and dried with hairdryer, been working a treat since! Cost of a pentalobe driver!
