    • Remove the plastic cover adhered to the battery contact board.

    This plastic cover wasn’t included with the new battery so I placed the original one back in. Was it supposed to go back in? This detail wasn’t clear since the original cover didn’t fit exactly over the newer battery connector. Plus any stickiness of adhesive that may have been there was gone.

    • Remove the following screws securing the battery connector board to the logic board:

      • Two 2.8 mm T6 Torx screws

      • One 7.0 mm T6 Torx shouldered screw

    Top screw in this image was not a T6. I found that a T5 bit fit this one.

    • Remove the wide head 6.4 mm T6 Torx screw securing the battery connector to the logic board assembly.

    I lost this screw! How important is it? Will it be okay with just the 3 previously removed screws?

    • Carefully lift the battery connector board up off the logic board.

    • It is recommended to bend the battery cables just slightly, to keep the board suspended up above the logic board and out of the way.

    • Do not fold the board completely over, or crease the cables, as this may damage the battery.

    • Grasp the Interposer with tweezers.

      • 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.

    • 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.

    How can I remove interposer I m not able to remove it

    Raunak - Reply

    you must lift it absolutely vertically, or it fouls against the locator pin in the corner- you can easily get the impression that it won’t come over the end of this pin- almost like it’s rivetted in. it isn’t. get a good grip on it with the tweezers in the centre hole & one of the sides, & lift it STRAIGHT up.

    • 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.

    • Use the flat end of a spudger to pry the right side of the I/O board data cable connector up off its socket on the I/O board.

    • When prying the I/O board data cable connector from its socket, make sure to pry the connector itself and not the socket. Prying the socket may cause irreversible damage to the I/O board.

    • Use the tip of a spudger to flip up the retaining flap on the right fan ribbon cable ZIF socket.

    • Be sure you are prying up on the hinged retaining flap, not the socket itself.

    • Pull the right fan ribbon cable straight out of its socket on the logic board.

    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?

    Still no change? I mean that cable doesn’t necessarily have to come off. Just a little irritating and in the way for the reinstall

Thanks a lot for this guide ! I completed it with no problems… I never did this kind of unmount/repair and thanks to the iFixit  Essential Electronics Toolkit, ++Arctic Silver Thermal Paste++ and Arctic Silver ArctiClean it was a breeze to complete. I think I have put too much thermal paste but it is no problem. The macbook now works like a charm.
