Use this guide to replace a faulty logic board.

Don't forget to follow our thermal paste application guide before you reinstall your heat sink.

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

    • Two 2.3 mm Pentalobe screws

    • Eight 3.0 mm 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.

    For all the screws you use the P5 pentalobe screwdriver?

    Carlos - Contestar

    Pentalobe is only for the screws on the bottom cover. The Torx screw driver is for the remainder.

    Fredrik -

    Is the Pentalobe screwdriver mentioned in the tools list? I did not have one so I used a filed down flat blade screwdriver. Not a fantastic idea, but it works.

    Alex Birkett - Contestar

    Yes, it's mentioned on the top of this page. P5 Pentalobe to be precise. I didn't have one either, so I bought one from iFixit and that works fantastic. An absolutely precise fit, which is important especially when you might open your MacBook a couple of times during the years you own it. Not using the correct tool might do more harm to the screws than you want! I once had this with a Lenovo Yoga 3 Pro, which has Torx screws (T4 I think) and I used cheap Chinese quality tools, with the result that both the tool and one of the screws are damaged.

    addvariety -

    the macbook in the picture is 2012. does it has the same structure as 2013?

    Edison - Contestar

    I never, ever, ever considered using anything but the correct tool on the Pentalobe screws. Too easy to strip and void your warranty (if still in effect), as well as make it almost impossible to get inside later for another upgrade or repair. The Wiha P5 Pentalobe screwdriver fits like a glove and costs only about $11 (a fraction of your drive's price)at Amazon.com. Get it!

    marketing - Contestar

    is P5 supposed to be for all 10 screws? it works on the 2x 2.3mm at the top, but not for the 8x others for me. what size screwdriver for the 3mm? thanks

    monsieurescargot - Contestar

    Yes, the p5 works for all 10 pentalobe screw heads for bottom cover. The the different size mm reference only refers to the difference in length of the screws, but again both heads are p5.

    I followed this exactly and was able to replace my broken trackpad. I did not have to replace the ribbon OR the battery. However I would suggest getting the ribbon since it’s fairly cheap, as for the batteries I was able to do it with a card only. I didn’t use any heat or the liquid but it takes some time. You really have to work the card in there to release the glue. Also you must be very careful not to bend the batteries or damage them, if you do you must replace with new. This took me about 1.5hrs and my computer works like new. Apple cost for this job was around $450, I did it for $120. Big ups to ifixit for this awesome tutorial, tool set and parts!

    On a side note, only use quality tools, the cheap ones will break or strip the screws.

    Dustin Steward - Contestar

    Note that the eight 3mm screws have a shoulder under the head, while the two 2.3mm screws are “full thread”, i.e., there is no shoulder under their heads. It’s important to put the two screws with no shoulder at the hinge of the cover.

    All ten screws require a P5 Pentalobe screwdriver, preferably with a magnetized tip to help hold and position the screw.

    All of the screws have blue “Loctite” thread locker compound on their threads. This is to help prevent the screws from working loose and falling out. Don’t attempt to clean the Loctite from the screws — leave it in place, and it will continue to help prevent the re-inserted screws from working loose.

    When replacing the bottom cover, it is a good technique to insert and BEGIN tightening all ten screws BEFORE fully tightening any one screw. After all the screws have been started, then go around and finish tightening all of them. By doing this, you make it easier to feel that each screw has been started properly, and is not “cross-threaded”.

    doubleclutch - Contestar

    A good technique for starting to thread the screws when replacing them is to position and align the screw, and with the driver, gently turn the screw in the REMOVAL direction until you feel and hear a slight click. This click happens when the leading thread of the screw drops off of the leading edge of the thread in the hole — this is the point at which the threads are properly positioned for engagement. You can now turn the driver and screw in the TIGHTENING direction. This technique will help prevent accidental “cross-threading” of the screw, which will damage the threads permanently.

    Note that this is a useful technique when installing ANY threaded fastener.

  1. Wedge your fingers between the upper case and the lower case.
    • Wedge your fingers between the upper case and the lower case.

    • Gently pull the lower case away from the upper case to remove it.

    This takes a bit more effort than you might expect. Put your fingers where shown and lift about 3inches. With enough upwards pressure the plastic holders will “pop free” and the bottom will come off easily.

    hamiltont - Contestar

  2. The lower case is connected to the upper case with two plastic clips near its center. 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 with two plastic clips near its center.

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

    There are two screws that are shorter-they go to the back near the vent.

    wrbandllm - Contestar

    This was already mentioned at the start, it says 2x 2.3mm screws and those are coloured red instead of orange for the other ones in iFixit's image.

    addvariety - Contestar

    What is the black vinyl-y sticker on the inside of the case (some sort of shield?). I was forced to slightly puncture it in order to replace the feet on my laptop. Thanks in advance.

    Tommy Huang - Contestar

    When I got the back off, I found this piece loose, any idea what it is? about 9mm long frosted plastic

    This wording I found quite confusing. They just mean when putting the lid back on that you just removed in the previous step, push here.

  3. If necessary, remove the plastic cover adhered to the battery contact board.
    • If necessary, remove the plastic cover adhered to the battery contact board.

    Do you know where I can purchase this plastic cover? Mine is missing and no one will work on my computer without it.

    jodieabc - Contestar

    There is no point on going near the battery or logic board. I cut out these steps with no issue. It is precautionary but unnecessary.

    I have a friends MacBook Pro that has some water damage that caused the MacBook not to be able to use battery power, but still work when plugged into A/C. Upon further inspection I can see visible corrosion on a few of the 9 cables going from the battery connector to that small circuit board. Is it possible to just replace that circuit board?

    jramsey21 - Contestar

    I have the some problem. I was thinking to replace the whole battery but I am not it will solve the problem. Any suggestions?

    salvatorebarbera -

    Sometimes it can be enough to just clean the contacts without having to replace the entire board. Dosent work for complicated IC's like plcc type, where corrosion is underneath the chip. Here you will have to reheat and reapply the IC.

    andrehedegaard -

    Hi,have you find the solution for your battery? I also have same problem, run with plugs but it battery not supporting… as soon the plug of it goes off

    Jewel Rahman -

    Have either of you replaced the battery and/or circuit board to fix the MacBooks with the water damage ? I have the same problem with the MacBook working fine when connected to power but dying immediately when the power cord is removed.

    Steve - Contestar

    Hi, Steve. I had the same problem: Macbook Pro 15 retina with coffee damage. And it worked fine when connected to power. I made it working after replacing the whole battery. It seems that circuit connected to the battery becomes disabled to prevent short circuit.

    Vadim Gribanov -

    When placing the battery connector back into the socket on the logic board, check that every part of connector is pressed down. You should hear a soft click when it's back in place.

    Ethan Tarquin - Contestar

    Thanks for the comment. My MBP isn’t powering on after I walked through these steps, and I assume it is because the battery connector isn’t fully connected. (I can’t check yet since I borrowed the pentalobe screwdriver)

    Caleb Steinborn -

    I thought I made sure it was connected but when running the computer it only detected the battery but couldn’t power it. I had to run with power adapter. Also it didn’t charge. I guess some pins were connected but not all. To verify that all were connected I removed the plastic cover, placed it carefully completely flat, and then reattached the plastic cover. After that it worked!

    Jonas Ehrs -

    If I only want to replace the trackpad cable, then which steps should I skip? This step seems unnecessary

    Parth Gudhka - Contestar

    Removing the battery connector took a bit of finagling. It wasn’t as easy as one would think. Be very careful when doing this as they warn to not damage it. Otherwise great instructions!!!!

  5. Bend the battery connector up out of the way to prevent accidental contact with its socket during your repair.
    • Bend the battery connector up out of the way to prevent accidental contact with its socket during your repair.

    If you miss or let this step for later like I did, the power left in the battery even though the computer is completely shut down, will screw up the I/O board cable like I did. I noticed this after I put all the pieces back, turn the computer on and surprise, no wifi hardware is detected. -.-

    sebasgaes - Contestar

    I put a small piece of blue painters tape on the battery connector contacts to prevent it from accidentally making a connection and shorting. This helped keep things a bit more protected.

    LaymanLab - Contestar

    That’s a great idea!

    David Lilliebridge - Contestar

    I used a small piece of paper to prevent the connector from connecting, no need to wrestle with even low-stick adhesive.

    How should I reapply those little foam stickers? I guess not with normal glue.

    bboy.sidekick - Contestar

    I found that the adhesive came up with the foam except for one screw. The adhesive just stuck to the head of the screw so I left it intact as much as possible and just pressed the foam back on. It doesn’t take much to keep them in place.

  9. Remove the heat sink from the laptop. When reassembling your computer, follow our thermal paste application guide to reapply the thermal paste.

    I bought all the tools necessary from iFixit except for the cleaning solutions for this step. You can just use isopropyl alcohol with a microfiber cloth to clean the thermal paste off before re-applying a new coat.

    • Use the tip of a spudger to push on either side of the the iSight camera cable connector to walk it out of its socket on the logic board.

    I found this to be the most difficult step. There is a need to get positioned so that you have the leverage to push hard enough at exactly the point shown in the photo without risking slipping and perhaps damaging the CPU nearby

    Um, this guide should include steps for applying thermal paste, including instructions to clean the mating surfaces, and pictures showing how much thermal paste to use.

    TheIronGiant - Contestar

    Hi @theirongiant, there are generic thermal paste application instructions linked in the introduction “Don't forget to follow our thermal paste application guide before you reinstall your heat sink.”

    Sam Goldheart -

    Make sure to put the end furthest away from the hinge under the ribbon cable first.

    Then place the hinge side. The screw furthest away from the hinge is partially obscured by the ribbon cable.

    If not placed correctly, ribbon cable damage may result.

This guide helped me repair my MacBook Pro with no prior knowledge of working on computers. I purchased a new logic board after mine broke from eBay, from a seller named L2 Computer Inc. and followed this guide using the iFixit pro tech tool kit and their thermal compound application set to reinstall the heat sink, and my computer turned on right away. Everything was so easy using this guide. The pictures are so good at showing how to do the steps, and the tool kit had really nice tools which made the whole process very simple. I am so thankful that you all help people fix their computers. It could not have been easier with this guide. It’s very well-written.

COURTNEY DYE - Contestar

Help me fix my MacPro. You are so good, Showing step by step. Make it very simple. Very thankful helping other sharing your skill. Tony, October, 2018

Great guide. Had issues with my Late 2013 MBP and narrowed it down to the logic board. I replaced it with a Mid-2014 MBP logic board as they are interchangeable thanks to this detailed guide. Laptop now fixed and upgraded!

velocity211 - Contestar

I can’t say enough about how well done this guide is for replacing a late 2013 MacBook logic board. The step by step with pictures were professional and spot on. I had a 4GB, i5 that had got to the point where I had to keep using a memory app to free up memory every couple minutes. Not being able to upgrade memory I was left with little options other than to buy a new one. After finding this site, I got a new logic board with i7 and 16GB of memory, I was able to turn my crippling MacBook back into a robust laptop I can once again enjoy using hopefully for at least a few more years. Bought the tools on here to complete the replacement and everything went without a hitch.

So a BIG thank you, thank you, thank you.. Keep up the great work on this site.. I know I’ll be back to check in on what’s available and when I have something else that needs to be fixed/upgraded vs buying new. :)

After replacing the Logic Board, is there any other steps afterwards with programing? After I replaced the board, the flashing question mark comes up. When I go into Disk Utility the HD is not showing up. If anyone has any input I would appreciate the help.
