    • Remove the following ten screws securing the lower case to the upper case:

    • Two 2.3 mm P5 Pentalobe screws

    • Eight 3.0 mm P5 Pentalobe screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

    If don’t have one of those neat project mats, then you can use small pieces of flattened blu-tack to hold the screws. If you arrange them in the shape of your mac book cover, and put the screws down methodically, you can get a one-to-one mapping of the screws to the correct screw holes.

    Or you can use an ice tray where you put the screws and the parts in separate bays in the same order as they come in the instructions.

    This is great! I used a small magnetic white board, and wrote on it to identify the parts as I went. This whole process, from the fast shipment to the great instructions to the complete, high quality, tool kit has been great. I’m typing this comment on my resurrected laptop. Thank you! Sue

    It would be a good idea if people recorded in the comments which screws go where so that, if someone lost their screw positions, they could recover them from the comments.

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

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

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

    The replacement cover doesn't seem to have the formed pads attached. I re-installed the original.

    • 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.

    when doing this with metal tweezers as instructed in the video, it was difficult to get off and apparently while i was trying to do it, the tweezers went too far under and i believe made contact with the screw underneath? there was a zzz noise, an orange flicker and a little stream of smoke that came out. i freaked out and put everything back together to see if the laptop even still worked, it turned on and everything but died right away (i drained it before doing the repair anyway, so i was surprised it turned on at all).

    i finished the battery repair and did several other things while in there. i have charged it all the way as recommended and will use it later on to see how everything is, im hoping that it’s a okay, but could someone explain to me what happened and the possible consequences?

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

    When reinstalling, be careful that the board lines up correctly and is completely seated in order for this screw to thread properly.

    • 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.

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

    Raunak -

    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.

    I would recommend to use plastic tweezers in order to reduce risk of damage.

    Martin Sippel -

    Second that. If you have thin heat shrink tubing, form some over the tweezer tips. If the tubing is thin and small enough in diameter you’ll see the serrations of the tweezer tips.

    • Remove the following screws securing the heat sink to the logic board assembly:

    • One 2.4 mm Phillips #00 screw

    • One 3.4 mm T5 Torx screw

    • Four 2.7 mm T5 Torx screws

    Hi,

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

    ddagonetroppo -

    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.

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

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

    • Remove the three 3.1 mm T5 Torx screws securing the left fan to the logic board assembly.

    • Lift and remove the left fan out of the upper case.

    • Make sure to pull the left fan straight away to simultaneously pull the left fan ribbon cable out of its socket on the logic board.

Conclusion

To reassemble your device, follow these instructions in reverse order.
