MacBook Pro 15" Unibody Late 2011 Logic Board Replacement

Neye ihtiyacın var

  1. MacBook Pro 15" Unibody Late 2011 Logic Board Replacement, Lower Case: adım 1, 1 resimden 1.
    • Remove the following ten screws securing the lower case to the upper case:

    • Three 13.5 mm (14.1 mm) Phillips screws.

    • Seven 3 mm Phillips screws.

    • When removing these screws, note how they come out at a slight angle. They must be reinstalled the same way.

    Step 1 (technically step 9 - replacing the base plate) Apparently one of my screws was a micron or two smaller than the others. This screw belongs to the hole above the optical drive, which is also apparently a couple of microns smaller than the others. It took seven attempts to figure which screw had originally been in that hole; all the other screws were too large, but fitted perfectly everywhere else.

    Bizarre much?

    Will - Yanıt

    It might be a matter of how the screws are driven in, and not that they're slightly different sizes. When I reassembled my MacBook, a couple of the screws, including the one over the optical drive you mention, were hard to drive in and jutted up a little bit instead of sitting entirely flush. Swapping screws didn't help. The solution was to unscrew them and drive them in at a bit of an angle - perpendicular to the slightly curved surface of the back plate where the screw holes were, instead of fully vertical with respect to the ground the Macbook is sitting on. Doing it that way, the screws were easier to drive in and they all ended up flush in their holes. Didn't matter which screws they were. (I swapped a few around just to check after reading this.)

    Andrew Janke -

    I had no such screw issues. Either there are differences in manufacturing lots or I just got incredibly lucky during reassembly!

    xtophr -

    I discovered a great way of organizing the screws. I used an ice cube tray and added the screws in order, keeping the different kinds together. So when it came to reversing the steps, the screw order was an added control step to returning everything in its place.

    Great advise! Love it! :)

    Ririds -

    I used to do that and that worked really great until I bumped it by accident and the entire tray went on the rug! I spent the next day sorting things out.

    Now I use these:

    http://www.sciplus.com/p/50-114-CLEAR-PL...

    The lower ones 50 to a package. I mark them w/ blue tape. Often if it's part like the fans, or the optical drive I'll tape the screws into/near the holes where they belong. I did this a lot especially w/ the bottom screws from MBPs until I'd done so many I knew exactly where the longer ones went.

    Richard Sato -

    I wrapped the screws in a piece of blue masking tape and wrote the number on the little pouch I made. Then I stuck the blue tape pouches on the underside of the case bottom in order.

    Roscoe -

    I take double-sided tape, put that on a piece of paper, stick the crews to that, and label them.

    jelimoore -

    Best I've found is a bead sorting tray. They're like $5 at Wal-Mart and they have a lid that seals up and won't let them jump between containers.

    maccentric -

    I take a sheet of paper, pierce the screws through the paper, take a pen and box the screws and write out what step they belong to.

    Nils -

    @Will, in my case I had the same result as you did. As a reminder to myself the next time I need to open the computer, I put a dot of white paint on those two screw's head and a very, very thin ring of white on the very edge of each hole, that way I'll know they go into those two holes.

    Roger - Yanıt

    Actually the four screws on the bottom were not threaded all the way up. I didn't check to see if the thread gauge was the same on them, but it wasn't until I had about four screws out (I didn't take them out in the order that the bottom all came out first) that I noticed a difference. I then took out the rest of the bottom ones to see if they matched the two that were already out that weren't threaded to the top. They did. So I went under the assumption that those were all bottom screws and when I put it back together everything went fine with no resistance.

    So there are three types of screws: Four for the bottom, three long ones as indicated and three others that might be slightly smaller than the bottom ones.

    Hi,

    Although its more than a year since your contribution, I thought you might be amused to know that it is not just that the screws go in more easily when at an angle, Apple actually drilled and tapped the holes at a 15% angle. I too had tried to drive them in straight. An Apple "genius" - I was in for something else - clarified the design for me. It was done so that the screws lay flush on the angled part of the lower case. Nice design, but since Apple encourages DIY memory and drive changes, they could have mentioned this little ... trap.

    Hey everyone, here's the very best way to PERFECTLY organize your screws AND keep track of the order of the procedure: Get a piece of plain corrugated cardboard and a pen (I like using a Sharpie). For EACH step of the disassembly, draw a simple diagram of the layout of the computer on the piece of cardboard, with dots or Xs where the screws are located. Right after you remove each screw from the computer, poke a hole in the cardboard in its corresponding diagram position with your screwdriver and place the screw in that hole. If there are other non-screw related parts to be removed, you can add notes below each step diagram to remind you of where they go or how they should be placed. This cardboard method is great not only because your screws will not go flying or get mixed up by accident if bumped, but each screw goes EXACTLY back where it came from and you can keep the cardboard as a template for future use if necessary!

    These instructions worked great for me. I ordered a replacement battery from Key Power (on Amazon) for my 15" Macbook Pro (mid-2010). Cost was $74 shipped.

    Battery came with 3 different screwdrivers to help with installation. I just needed the one size though, since my 2010 seemed to use all the same size screws.

    Thanks!

    Marcos - Yanıt

    During re-assembling (put the screws back in), it is important to note that the 3mm threaded holes are not completely vertical, but bent a little bit such that the hole direction is rectangular to the tapered surface. The force of the screwdriver must point towards the direction of the hole. Otherwise the screw gets jammed

    kusi - Yanıt

    There is a FOOLPROOF WAY TO ORGANIZE ALL SCREWS and other parts removed.

    Print the repair guide.

    Yes, the actual photo of the bottom of the laptop with the circles around the screws.

    When you remove the screw, tape it to the photograph.

    You will tape the screw to the exact location that you just removed it from.

    Same thing with any part you remove.

    Thanks Splash!!! I used your suggested method, and it was perfect: kept all my screws, and i was able to, very easily, put them back in their correct place. I greatly appreciated your feedback. Thank you for sharing!!

    Tommy Kedar -

    Thank you!!! This worked fabulously - even the I.T. people at my workplace were excited as they never thought to do that before. Replacing the battery took about 10 minutes!

    Worked like a charm! Took less than 20 minutes.

    It's Oct. 2015, and the fan cost me about $10. it was the same brand/model...

    SOME TRICKS -

    1- no T6 screwdriver- was careful using needle nose players to loosen 2 screws protruding up, then use a small phillips to push real hard into the T6 slots, SLOWLY turn , also used a small flat head screwdriver (for eye glass repair) was able to grab thread on T6's, made a small mark with screw driver across the top so I could see when it started to turn.

    2- no spudger -made one; cut a little strip 1/2" x 1 1/2" of plastic. couldn't get it to slide under plug, there's an edge where plug fits. so lifted old fan out, pulled upward on the plug it popped right out with very little effort. I used my home made spudger to push the new plug into place.

    3- download free "Macs Fan Control" This is how I was alerted to the fan not working in the first place. Program shows temperature of all key components in the computer.

    cheers- Durango CO!

    I will be buying a battery from you and using your instructions. I just installed a new CD/DVD using your instructions and 1) I feel like I owe you something and 2) Although more expensive, I have the confidence your battery will work. My current battery is the original with 1399 cycles in 7.2 yrs. A tech buddy had bought me a replacement and I installed it. I had just installed a new OS and the kernel_task went going nuts, using 90% of the CPU. Hours on the phone with Apple did not resolve the issue. On a whim, I put the old battery back in and Voila! But I cannot risk my battery swelling and going south on me. I am also going to buy your installation tools. Yeah, I already have them. But you can never have enough tools…or beer. And you don’t sell beer.

    Pete Banks - Yanıt

    The instructions say that I am removing PH00 screws. I found that my MBP, mid ‘12, Retina has pentalobe screws instead!

    jsandersonq - Yanıt

    This laptop definitely originally shipped with Phillips screws—but, Apple has been known to replace Phillips screws with pentalobes when one of their devices is brought in for service. Sorry for the rude surprise! Fortunately the correct driver is easy to find nowadays. [Blatant self-promotion alert!] If you support free repair manuals, consider picking one up from iFixit. Good luck!

    Jeff Suovanen -

    Me, too, and it’s plausible that this machine has been serviced by Apple in the past, replacing the screws as Jeff Suovanen suggests.

    iFixit shipped a pentalobe bit with the kit, but it’s too large for the actual screws, so it looks like I now need to get another bit. But what size?

    Jeff’s link is to a driver with a P5 bit, and that page links to a P2 screwdriver, but since I don’t know what size I actually need (and I don’t have a micrometer to hand) I’m reluctant to buy two on spec.

    Norman Gray -

    (The bit in the kit appears to be a P6, so I’m inclined to order a P5 and see what happens)

    Norman Gray -

    You’re using the wrong repair guide. This guide is for the 2012 NON-Retina MBP. You have a Retina MBP. The stock case screws in the 2012 NON-Retina are all Phillips, just as the guide says.

    Steven Wymor -

    To keep track of screws, I used the suggestions above by taping a photo of the lower case to a piece of corrugated cardboard and inserting/taping the screws in place. Also, as some have noted, the screws go back in at a slight angle; they are angled toward the center of the unit.

    Kristina Graham - Yanıt

    If your vision, like mine, is getting too fuzzy to be able to distinguish between a tiny Phillips screwdriver and a tiny Tri screwdriver, there’s an easy way. With a Phillips (or a Pozidrive) you can get two opposite wings to reflect the light from a lamp or window straight towards your eye at the same time. With a Tri (or Penta) you can only get one wing to reflect at a time, however much you twiddle it.

    Alan Waller - Yanıt

    There’s a very easy way to avoid cross-threading a screw thread, any size.

    Put the screw into its hole and start by turning it gently, slowly BACKWARDS. When you hear a little “Click!” sound, the male thread has just passed the opening in the female thread and is in exactly the right position to enter into it correctly when you start to turn in the correct forward direction.

    Remember, all drivers except hex (Allen key) and TorX need pressure to avoid slipping out and damaging the head. So even when you want to turn it in with LOW moment/torque, keep the CONTACT PRESSURE high.

    Alan Waller - Yanıt

    The keep the pressure on is on point. In my case once I loosened my first screw I thought I could relief my initial pressure. It was a mistake. I was doing the whole thing very slowly as a precaution. That helped me notice that the Phillips screw driver was sliding up out of the screw head. Not being sure why, I put pressure back on the screw driver until almost all the screw was out of the hole. Once out, I examined closely to find out that the threads have some sort of coating. It looks to me like some kind of locktite. Then I understood the importance of keeping the pressure on all the way through. It made me uneasy having to keep so much pressure on such tiny screws, but I found it was the only way to prevent damage to the “slots” on the heads. Anyway, all of them suffered some degree of damage, but I was able to successfully remove them and reinstall all of them back in their original holes.

    After reading this page on iFixit several times, I just could not face all the work of replacing the Logic Boards on two MacBookPro 2011s even if I was prepared to pay approx 400 USD (which I wasn’t). Then I read the reviews of a couple of folks who’d stripped down their machines and put their logic boards in the oven and, it worked! I wondered, if I just used my new Steinel Hot Air Tool (heat gun in my language) recently delivered from iFixit, on the logic board in-situ, without removing it? So I removed the battery, hard drive, and RAM and unplugged all the leads I could see WITHOUT removing anything else physically. Then using the 500 degrees set on the gun (setting 2) I ‘played’ the gun over the logic board for about 60 seconds on machine one with the restart problem (plus latterly, not completing start-up). Long story short… it worked! I spent a long time getting the s/w to load, but the commentary is too short to let me relate that part… ping me if I can help you do the same! blackaye@gmail.com

    • For certain repairs (e.g. hard drive), disconnecting the battery connector is not necessary but is recommended as it prevents any accidental shorting of electronics on the motherboard. If you do not disconnect the battery connector, please be careful as parts of the motherboard might be electrified.

    • Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

    • It is useful to pry upward on both short sides of the connector to "walk" it out of its socket.

    nails work pretty well as well...

    Sibe Jan Kramer - Yanıt

    At first sight I was confused when I read the description at this step, 'cause it seemed that disconnecting the battery connector was optional, in order to eliminate static discharge. While it's a helpful advice in other circumstances (as mentioned as an example changing hard drives), when changing the battery it is not an option - you have to disconnect the battery connector.

    It would have been better to mention the optional disconnecting recommendation in a side-note.

    Other than that, an excellent guide!

    Damienn - Yanıt

    the fact that this step is optional can not be stressed enough. i tried disconnecting the battery and in the process it short circuited which now leaves me with an even more expensive problem than i had before when i just wanted to change hard drives (at least the new hard drive works fine..)

    the hard drive changing worked though.

    nina - Yanıt

    Any tool used to pry on the battery connector must be non metallic, to prevent unintentional short circuit between the connector pins. In my case, my index finger nails were strong enough.

    Martin Mejia -

    Excellent guide, it was as easy as a breeze to replace my battery. I can't believe I nearly followed Apple in their saying that this part was not user replaceable. Great job for this description, and many thanks. iFixIt is THE reference for Mac owners.

    Patrick Demaret - Yanıt

    So - I have a weird comment about this. I wanted to make sure that I was getting the right model - so I opened up my laptop and then thought "well, why not just remove the battery while i'm in here, it's shot anyway". Though, I forgot about the stupid screws (Apple really did us over on that one!). Though I disconnected the battery connector and didn't bother to re-connect it when I was finished and just put the cover back on.

    Here's the weird part - when I went to turn my laptop back on...MY BATTERY WAS RECOGNIZED...AND WORKING! I was under the impression that the connector "connects" the battery's charge to the laptop, but this just doesn't make sense! Plus, now my very dead battery is in "normal" condition according to the system report. I haven't worked for apple, but have about 5 years of IT experience and am baffled by this! I'm starting to think i've experience a miracle! Has this happened to anyone else?

    Shelly - Yanıt

    Possibly disconnecting the battery caused the System Management Controller to reset. That might have been your problem rather than the battery itself. See http://osxdaily.com/2010/03/24/when-and-...

    Mazo - Yanıt

    I tried spudging the corner closer to the wires which was probably a bad idea. The corner broke off! I can't believe it was that brittle. So be careful. If it did it again, I'd aim for the corners AWAY from the wires or the sides themselves, though I seem to recall there not being much of a lip.

    Dave Kitabjian - Yanıt

    I used the spudger to gently ease the battery connector out. I then placed a q-tip between the connector and it’s socket to avoid making an accidental connection. A toothpick or some other soft stick might also work.

    Kristina Graham - Yanıt

    My battery connector had a shiny metal cover over it like a male USB plug. I had to take the 3 peace symbol screws oit and remove the battery before I could access thr plug properly. My battery plug also came off parallel to the board by walking the black plastic part off the metal part towards the battery. It required quite a bit of force to walk it off the connector. I broke a spudger trying. Something nonconductive but strong like a wittled down bamboo chopstick could work well.

    Pii - Yanıt

    Translate to Spanish:

    Para ciertas reparaciones (por ejemplo, el disco duro), no es necesario desconectar el conector de la batería, pero evita cualquier cortocircuito accidental de la electrónica en la placa base. Si no desconecta el conector de la batería, tenga cuidado ya que partes de la placa base pueden estar electrificadas.

    Use el borde de un spudger para levantar el conector de la batería hacia arriba desde su zócalo en la placa lógica.

    Es útil hacer palanca hacia arriba en ambos lados cortos del conector para "sacarlo" de su zócalo.

    The BATTERY MUST BE DISCONNECTED - it is NOT OPTIONAL if you are going to remove the logic board.

    These instructions are for Removing The Logic Board, so if that is what you are going to do the battery MUST be disconnected.

    The informational item beginning with the words “For certain repairs (e.g. hard drive), disconnecting the battery connector is not necessary … “ is NOT applicable to a set of instructions on removing a logic board and it should be deleted from this otherwise excellent set of instructions.

    Michael Walsh - Yanıt

    In my opinion the RAM should be removed first - i.e., before the battery is removed.

    The RAM DIMMS are just in the way if they are left in their sockets on the logic board until step 33.

    I cannot see any useful reason to not remove them very early in the sequence.

    Michael Walsh - Yanıt

    I disconnected the battery because it is an opportunity to reset the SMC (which is how the SMC has to be reset in some older Macs.)

    I found that I could not remove the Tri-Wing screws with the guide recommended Y1 bit. It was way too large and instantly started stripping the screw. The Y0 bit fits perfectly.

    • Use the attached plastic pull tab to remove the battery from the upper case.

    • If you're installing a new battery, you should calibrate it after installation:

    • Charge it to 100%, and then keep charging it for at least 2 more hours. Next, unplug and use it normally to drain the battery. When you see the low battery warning, save your work, and keep your laptop on until it goes to sleep due to low battery. Wait at least 5 hours, then charge your laptop uninterrupted to 100%.

    • If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook's SMC.

    WARNING!

    When I lifted my dead battery out, I saw two old 3 mm Phillips case screws lying loose in the bottom of the Unibody. I lifted them out using the magnetism of the Phillips #00 screwdriver.

    On gently shaking the case I could hear that there was another loose item still in there somewhere, so I carefully turned the laptop over to have it fall out – and the whole hard disk fell out, though it remained hanging by its cable! I discovered that the two screws holding the retaining strip (that runs the whole length of the hard disk between it and the DVD unit) had been completely loose!

    Nothing broke, but it was a nasty surprise!

    I had bought this machine second-hand as factory refurbished with twelve months guarantee – and gotten three old case screws and a nasty surprise for free! Apart from that, I’ve been really pleased with it.

    Alan Waller - Yanıt

    I purchased this battery and kit for my late 2011 MacBook Pro on Wednesday and received it today; Monday. Great timing with shipping! Instructions were VERY handy.

    I noticed after first full charge, the battery lasted a little less than 3 hours w constant web surfing… will it improve?

    yetixhunting - Yanıt

    yetixhunting - Sep 15, 2022.... Batteries are mass produced. it's not necessary that all the product exhibit the same characteristics.

    It's advisable, that you request for a replacement.

    The correct procedure to calibrate the new battery after it's installed, is to use it till discharge to 25% and then charge it to 100% and hold the charging process for 2 more hours

    Then repeat the process mentioned above namely; (discharge to 25% and charge to 100% hold for 2 hours etc)

    This is process is enough to almost stabilize the battery.

    But remember, you'd not obtain a result of OEM standards, in any case. Apple standards are very stringent and such standards will be be there in other manufacturers. Meaning 7 hrs continuous use, when new.

    • Remove the three 3.4 mm T6 Torx screws securing the left fan to the logic board.

    • In some models, these T6 Torx screws may be 3.1 mm long.

    Je vais juste vous surprendre car je suis français.

    JI'll just surprise you because I am French .

    I understood the problem of the left fan. In fact the problem is with the design at Apple. The fan housing is too narrow vertically a few tenths of millimeters. This is why so many problems . The left fans deteriorate very quickly.

    The solution is very simple. Buy a new fan in China, it is the cheapest and level it's very fast delivery . Warning it comes fan already used but in good condition.

    The thing to do is to over- raise the fan does not rub and deteriorating. To do so just buy a zinc washer 3 mm diameter available from my local hardware store ( € 3 for 70 pieces ) and place it under the black screw fully right and top right . The over- elevation leads to no longer have friction effect.

    Thats ALL !!!

    on my screwdriver set, the T6 screw driver felt wobbly. It felt like I would strip the screw if not careful. So I used a T7 screw driver, and it was much more snug.

    • Use the flat end of a spudger to disconnect the left fan connector from the logic board.

    • It is useful to twist the spudger axially from beneath the fan cable wires to release the connector.

    • The fan socket and the fan connector can be seen in the second and third pictures. Be careful not to break the plastic fan socket off the logic board as you use your spudger to lift the fan connector straight up and out of its socket. The layout of the logic board shown in the second picture may look slightly different than your machine but the fan socket is the same.

    I successfully removed my right fan, cleaned it and installed it back. But when it came to the left one I accidentally broke the connector from the logic board. Now I'm left with only one functioning fan. I'm using an external laptop fan. Do I have to replace the whole logic board or can it be fixed somehow?

    I used the J000 bit (I think this is a JIS bit, not Phillips) for these screws and they seemed like a much better fit. It seems like the screws aren’t actually Phillips (ie. with the curved, cam-out corners) but are squared off.

    On mine the small black piece of plastic directly south of the plate we just removed that is connected to the aluminum frame underneath by two screws was broken in the middle. Can’t find what this piece is called or what its purpose is.

    As a couple of others have mentioned (above), I too had trouble getting these two screws out too. My problem was that they had corroded and locked into their threaded sockets. Also, the corrosion had rotted out the inside shape of the Phillips slots so that no screwdriver would fit properly.

    this almost trigger panic button in my head, since after reassembly, my macbook wont turn on at all. turned out the keyboard zif cable is not fully inserted to the socket, and since power button is also connected through those flex, its no wonder it wont respond when i press it. Re-seat the zif flex and everything went great.

    I used a piece of sticky tape that I attached to the ZIF cable, then pulled firmly on the tape (attached to the cable) to get the ZIF cable to seat properly. The tape held to the cable, the ZIF cable seated properly, and the keyboard worked.

    shmianco - Yanıt

    REINSERTING THIS CABLE WAS ABSOLUTELY THE MOST DIFFICULT STEP IN THIS WHOLE PROCESS!

    Key points:

    •Make sure that it's inserted evenly. It's tempting to get one edge in, and then the other, but that approach will prevent it from seating properly.

    •The cable goes all the way in. There is maybe 1/16" of the little grooves showing, but not much more.

    •Once the cable is properly seated, use a piece of tape to pull it all the way in, and keep the tension on the tape as you use a sprudger to flip down the retaining flap.

    •It's a fragile connection, and if you break the cable it's a top-case or keyboard replacement, which is either expensive or a PITA, so patience is key.

    The comment Kal left about lifting the retaining flap is key during reassembly!

    I, too, totally missed that there is a plastic “bar” covering the end of the pins. Without that lifted up, it’s %#*@ near impossible to push the connector in since the flap/bar is putting pressure downwards.

    With the retaining flap down, it comes out without too much effort. But putting it back in is a whole different story. Be sure to lift it up!

    Justin Blecher - Yanıt

    For reinserting, just be patient, lining up the ribbon, keeping a good hold on the tab, and applying even pressure along the ribbon, slowly, firmly reinserting. If the power button doesn’t work when you put everything back together, you will know the ribbon needs better connection. I promise you can do it!

    hyde244 - Yanıt

    Even with the warning, I tried to flip up the socket. It looks unusual, not a standard zif socket. Try gently pulling (not lifting!) the cable to see where the cable ends and the socket begins. There is more socket there and less cable then it looks!

    • Grab the plastic pull tab secured to the display data cable lock and rotate it toward the DC-In side of the computer.

    • Pull the display data cable straight out of its socket on the logic board.

    • Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.

    The metallic flap controlled by the plastic handle looks like it could easily break... a safer route is to grab the shielded cable after rotating the metal flap out of socket and gently pry it out of the socket by applying force parallel to the logic board. It will probably take a few minutes but you could save yourself some gray hairs.

    I really advise you to remove the cable retainer (one 8.6 phillips, you can see a photo in the display replacement tutorial) BEFORE unplugging the cable, to have more freedom of movement (to plug it in back it's even more important).

    Really great site!! replaced a LB in an mid 2010 MBP with kernal panic crash. Fixed! No issues with detailed procedure and comments. So I'll add one for this step. This was the simplest step really. Additional clues. (Wish I could post a pix). Look at the gold conn in the pix above. Note that the cable mates with the conn with the 2 tabs each side showing full insertion. The silver retainer pops up, bar away from the cable. Using my custom tool, a small screw driver, filed really small as I don't have a #000 Phillips, release the retainer, then carefully wedge open the tab on each side, inserting your "tool" in the slot. Neatly and slowly, the conn comes apart. Putting it back together, once the conn is alligned, just push alternately on each tab. Doesn't take much effort, better that pushing on the cable. I also appreciate the comment that removing the clamp, both clamps with one screw actually, makes this easier.

    Bruce Rayner - Yanıt

    This made a difference for me. I put my arm behind the computer to pull the hinge and tape everything away from me out of my way and holding out with my thumb and walk each side and bit by bit using the tool. I’ll add be very careful that it is steady parallel force. Also if you can’t get the hinge clip down when the cable seems in try steady flat force across the clip of the hinge with the tool alternating with walking it in even more with your thumb on top holding it down so you don’t actually accidentally pry anything perpendicularly up.

    Aaron -

    This is indeed a tricky step. First time, after following all the steps and reassembling I had no screen, which freaked me out. Luckily, another go at the connector did the trick and now I’m a happy owner of a macbook with a new trackpad. Thanks!

    This step is really unclear! After grabbing what I thought was the “plastic pull tab” and having it come off in my hand, I was clueless about how to proceed. After puzzling over it for about 15 minutes, I saw the actual “plastic pull tab”, which was against the mother board near the fan. Pulling this upward unlocked the metal hinge and everything else was obvious after that.

    I agree, this step was unclear. Part of the problem may be variations between logic boards. Mine did not look like the one pictured here.

    Getting the DC board back in required a non-trivial amount of force to get it into position and lined up with the screw holes. It seemed to want to sit away further from it’s hole in the external case than it had to be to line up. I eventually got it in by leaving the main logic board out of it’s final position (but with the cable connected), which allowed me to get the leverage to push the DC board in so it would line up and be screwed in. Once it was in, I then positioned the main logic board and screwed it in.

    The thing that caught me on this step was that, at least on mine, the speaker box was glued/taped to the case, and so I got rather nervous trying to remove the logic board as it wouldn't move until said adhesive was pried apart. Thank goodness I knew the difference between the sounds of "board breaking" and "adhesive separating", but this step was still rather harrowing for me.

    The microphone cable was easy to pry off the logic board for disassembly. For re-assembly, I was having a heck of a time getting the connector to connect to the logic board. There just isn't enough room to get your hands and tools in there and still see what you're doing (unless you're a dentist and you're used to that kind of thing). Anyway, I finally got brave and pulled the round, rubberized microphone from the case. I connected the short cable to the logic board, set the microphone in the made-for-the-microphone housing on the logic board, hoping it would stick itself back to the case once the logic board was in position, and I was back in business. In this case, simply stating "reverse these steps for reassembly" wasn't very forthcoming.

    Pulling the microphone off the case is key to reassembling. Place the mic back into the cut-away in the speaker housing and plug the connection into the backside of the logic board

    thx graciaaaas :)

    When I did this step the microphone was REALLY STUCK to the upper case, it actually stayed stuck to it and disconnect "itself" from the mother board while I was lifting up everything.

    Finally, there was no damage : I separated the microphone from the upper case while reassembling, then connected it back to the mother board and put it on its housing.

    Greg - Yanıt

    Count the number of connectors as you remove the board, so that when you put it back one does not get lost under the board and you can't figure out why it won't go in. You should do this.

    If you laptop was getting hot when charging then be extra careful in this step because the foam pad under the logic board my have started to fuse to the casing. If the pad seems stuck then use a knife to gently pry it up.

    I have the same case with Joseph Sikorski - it's hard to pull out the mother board because the speaker is glued that I thought their are remaining screws that hook in to it. Better use flat spudger to pry the right side that is stuck when you pull the left upward first.

    Auldz Buzz - Yanıt

    Repairing a friend’s laptop… I wonder if the “glue” between the speaker and case is actually juice or soda, lol

    Sarah Ybarra - Yanıt

    This part was highly stressful. The microphone/left speaker assembly are fused to the underside of the logic board. As you are facing the project according to the layout in these photos, the mike assembly is on the right side of the logic board, towards the top end. It is fused to the logic board but it also has adhesive sticking it to the upper case. As you lift, you have to insert a long spudger flat end down into that corner and move it back and forth between the mike assembly and the upper case, and it will release. Be very patient, focused, and slow. The spare part I bought from iFixIt had an extra speaker there in case I messed up, but I did not need it.

    For reinserting the logic board, it helps to have a second person helping hold connection points to the side so you do not accidentally lay the logic board on top. Just go slowly, being mindful of all connections. (best to start by properly seating the DC power unit in the upper right corner)

    hyde244 - Yanıt

    This step need a better picture of how the speaker and microphone looked from beneath the board, so people can understand where they should pry with the stick tool to wiggle the adhesive. In my case, it was the microphone that stucked, luckily the connector of the mic itself wigle off when i pull the board sideway. N fortunately the connector wasnt torned.

    For any of you have difficulty in this step i would suggest to actually disconnect the socket of the mic from the board first, and then only pull the mic itself from the upper case.

    • Remove the heat sink from the logic board.

    • If the heat sink appears to be stuck to the logic board after removing all six screws, it may be helpful to use a spudger to separate the two components.

    • If you need to mount the heat sink back onto the logic board, we have a thermal paste guide that makes replacing the thermal compound easy.

    Strictly speaking, there’s no absolute need to remove the heat sink, unless you need to clean and re-apply some cooling past. The steps concerning the left speaker and the microphone following this step in this guide, can be done without it.

    this is the only step iʻm really not sure if it worked - i donʻt know if i got enough heat sink paste in. feels a little warm with a fan pad under the computer, but maybe thatʻs just normal. i HIGHLY urge reading the linked section of doing the thermal paste. i hope i never have to do it again, unless i know i got it right this time.

    Kahana - Yanıt

    There is another flat black rectangular heat sink between the heatsink listed above and the speaker/microphone bracket.

    It is worth replacing the thermal paste under it too. It is held in place by two T6 torx screws.

    Michael Walsh - Yanıt

    I second this. My new logic board didn’t come with this rectangular heat sink and does not have screw standoffs attached to the motherboard. I see that new logic boards don’t seem to have it yet this guide and several others already have it attached on. HELP!

Apple had a replacement service for late 2011 15inch MBPs which cured a mysterious fault which rendered it un-usable. I had mine fixed at a Genius Bar but my mate who also bought one has missed the program and has a completely dead MBP. Am I right in assuming that following your procedure above and using one of your logic boards would fix this?

JoeStoner - Yanıt

Hi everyone,

recently the GPU (Radeon 6750M, 512MB) on my late-2011 MBP died.

Currently I’m considering getting a 2nd hand logic board and replace my current logic board with it.

I found the following one at a decent price:

- early-2011 with 1GB GPU

My question is, will it be compatible with my MBP, which is late-2011 and with a 512MB GPU?

Thanks!!

Guy.jacquemond Your GPU just blew up, the transistors are mostly broken due an thermal design error.

You have two choices find: a second hand “new logic board” (or in Apple supply chain management). But if it’s not a new board, it’s GPU will blow sooner than later. You can’t change the chip itself because it does exist, made to order for Apple by AMD and Nvidia. Reballing just subject the GPU to thermal stress and can make enough transistors reconnect for a little while and die again in a week or two.

The other choice is disabling the GPU, no small feat, in the EFI before MacOS launches and then enabling proper Kext to avoid overheating your system, because even when disabled, the GPU still receives power and goes in a thermal wild ride. Making you Mac enter into thermal throttling and in the long (short) run will probably damage the CPU too, check the following forum thread at MacRumors: https://forums.macrumors.com/threads/dis...

Hi guys I have the same problem about 3 years ago, I sent my MBP to fix and it was still ok with the Apple replace program, so I got a new Logic board for free…

But that happiness didn’t last for long cause a year ago it happened again, ( the problem is that the new logic board is also defective, has the same GPU) this time Apple had finished it's replace program. So I search the web and got a solution which is disable the defective GPU by getting your MBP boot into single user mode and then write some codes:

https://gist.github.com/cdleon/d1eff7246...

Manu - Yanıt

The problem with this solution is that you can’t update your computer, even a security update will overwrite the code and you will get back to the problem.

You can try again the same process.

For some reason I couldn’t do it again. (Couldn’t get my MBP boot into single user mode). So again I was searching for a new solution. And I fount this:

https://youtu.be/vbXb0gfRxEY

What this guy does is the same idea of disabled the defective GPU and letting your MBP run with the integrated intel GPU but he does it by flashing the AMD GPU, which in normal English is disabling the GPU by hardware, so you won’t have again to write the code even if you update your MBP.

I took out the Logic board

https://gist.github.com/cdleon/d1eff7246...

and send it to him, (I live at France) he did it, he fixed and now I have again my MBP working.

I am really thankful, he is very professional, here’s his contact and I hope you’ll fix your MBP also.
