Introduction

Use this guide to replace the logic board.

    • 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

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

  8. 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

    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.

    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.

  10. 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.

    Bummer. It wasn’t clearly communicated how to separate this connector, and I accidentally pried the socket from the board. The connector slides out horizontally, so don’t pry up from the bottom.

    Yes. That's a tricky little guy! I'm very lucky that I didn't break it! I couldn't figure out which direction to 'walk' it, but after reading the comments above it became more clear. When I first started trying to detach it I was trying to lift it up like all the previous connections. It was giving too much resistance, so I put the magnifying glass over the picture and then the connection. Back and forth I was looking. My hand slipped. I thought I broke it! But I saw that it had moved 'backwards' a bit. Then it became clear on which way to 'walk' it. It moves back in the direction of the cable it's connected to. It slides in like the newer fuses do in a car. A neat little learning experience! Thank you folks who add comments and to the people who put this directorial together.

    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?

    Like @victorgav mention, Just need a step before this one, which is to remove the cable that goes across the top of the fan.

    Thanks for bringing this up! It looks like the guide was missing the iSight cable disconnection steps. I’ve added the missing steps.

    • Carefully grasp the corner of the logic board (opposite of the I/O ports) and lift the logic board out of the upper case.

    When re-installing the Logic board, be careful not to trap any of ZIF cables under the board.

    You’ll need to tilt the board up from the end away from the DC-IN board in order to get the IO connectors inserted all the way. Be careful with the little fingers on top of the IO connectors.

    I had previously replaced the battery with the Newer Tech battery. The battery cable is not as flexible as the original battery, making the removal and insertion of the trackpad cable difficult.

    Removing worked fine........ Followed every step carefully.... Getting another board in will be another chapter.... And hopefully the machine will work again.

    Thank you ifixit.......

    Yes! I just finished. Yay!! Couldn't have done it without this tutorial, so Thank you very much!!! I think installing the new one will be more difficult. I could have just went out and bought a new one, but this has been much more fun!

NOTE: The logic boards you are placing into your Macbook Pro as a replacement probably are not coming from systems that are current and actively being used (they may have been on the shelf for a while)…more importantly they are almost certainly not coming from systems that were fully updated and running MacOS High Sierra. Realize that if you have updated your Macbook and are running High Sierra, your hard drive has been converted to the latest APFS Apple file system. In order for an older logic board to be able to read any of your APFS hard drive will require that the logic board gets the latest SMC/firmware updates. Without this you will not be able to boot from your hard drive. See how I was able to correct this dilemma here: Hard Drive/OS not recognized after logic board replacement
