    • The lower case is connected to the upper case at the center, with two plastic clips.

    • During reassembly, gently push down the center of the lower case to reattach the two plastic clips.

    • 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.

    • Use tweezers to remove the small plastic cover located near the bottom right of the battery connector board.

    Is adhered to screw beneath, so lift firmly and slowly.

    • 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.

    What happens if the Battery Contact Board fails?

    • Use the flat end of a spudger to pry the headphone jack cable connector straight up off its socket on the logic board.

    • Gently bend the headphone jack cable to 90° up from the logic board.

    • Bending the headphone jack cable will allow you to disconnect the left speaker cable connector without having the headphone jack cable in the way.

    • Wedge the tip of a spudger beneath the left speaker cable connector.

    • Gently pry the left speaker cable connector up off from its socket on the logic board.

    • Be sure you are prying up on the connector, not the socket itself.

    • Remove the following screws securing the left speaker to the upper case:

      • One 6.8 mm T5 Torx screw (top right)

      • Two 6.3 mm T5 Torx screws

    • The corner screw may be covered with a foam pad. If so, use your tweezers to peel it up and remove it.

    The 6.3mm screw appears to be on the lower central part of the Macbook that I'm working on.

    On my Early 2013 A1425 EMC2672 the screw in the corner is under some metallic foam that needs to be removed before the screw.

    Be very careful on this step. If you aren’t you can snap the plastic on the corners where the screws go in. Remember to go slowly when spinning the screws back in, it doesn’t take gorilla torque to tighten them, just take it easy!
