Use this guide to replace the left fan.

    • 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.

    On my model A1425 these were all 1.2mm P5 screws. They all looked the same to me.

    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

    Please put an arrow on the picture of the bottom to show where the clips are. NOT clear. The black gizmos in the middle??

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

    Hi, any issues with you computer after a year? I didn’t put mine back in either…

    Kevin, I forgot to place mine back in! How is your laptop doing without it?

    Dominic Radcliffe - Ответить

    My “on button” isn't working. I was wondering can I just disconnect the battery like this, and plug it in to turn it on? Which is shown possible on earlier models on YouTube.

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

    Check your speakers for the screws. The magnet for the speakers is strong enough to stick to them.

  7. 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.

    • 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 - Ответить

    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?

    racoon2956 - Ответить

    Be extra careful when tightening down on the interposer. When I powered on upon completion, the battery was not connected. When I opened it back up, I saw that one of the little metal nubs holding the interposer in place had snapped off (the one on the side, not the corner). I was able to carefully tighten the wide head screw back in, watching the alignment, and the battery was successfully recognized. Hopefully the connection holds up.

    Doug Krieger - Ответить

    So something similar happened to me. One the the metal alignment nubs snapped off, and when I went to screw down the interposer it started emitting a burning smell. Do you guys think I fried the board? There doesn’t look to be any visual damage but the computer wont turn on.

    Where can I buy a replacement interposer? I may have lost mine in the process of replacing the battery.

    I bought an interposer on amazon

    Kris K - Ответить

    I think I snapped off the nub as well, and the battery is not recognized . Replacing the interposer did not help, or trying to align it right. will have to try to replace the battery next.

    Kris K - Ответить

    I really dont understand why to unplug so many parts if the SSD can be easily removed without all this effort. its not even connected to the battery..

    Gabriel Beolchi - Ответить

    I was reassembling and put the interposer back and when the battery contact board touched the interposer, there was a little spark. Should I be worried?

    Sandy Lyon - Ответить

    I skipped this step but still OK.

    Takashi Nakano - Ответить

    Warning to all: I snapped off the alignment nub as well, as I removed the interposer, and now it won’t start with a brand new battery. Any solutions to a “snapped nub” issue?

    • 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.
