MacBook Pro 15" Retina Display Mid 2012 I/Oボードの交換

Woohoo, much easier than I thought... Just got confused with the bottom case screw driver but after figure out it was P5 then everything went smooth.... One thing I wanted to upgrade was the wifi to ac and got one on ebay!

If you have 54 Bit Driver kit, please use Star 5 driver to remove screw for rMBP 2012 Late

Where can I find the driver for the MacBook Pro Retina Display 15'4 i7 on your website iFixit please.

It took about 40 minutes due to an extreme measure of caution but I did it! The only real difficulty was reattaching the screen to the base (yes you have to pry the hinges open) and re-connecting the camera wires. After a few tries the camera wires finally came together. I'm hating Apple for all it's frailty and magical screws but I love ifixit!

Simple guide, but it solved my problem. Was wondering why the top two screws weren't going all the way down. Hadn't realized they were 0.7mm shorter.

Good to list the bit needed to open the case: P6

Much easier than expected. Sounds like several people had trouble with the backlight. It is possible that they damaged something by not first making sure to power down the computer completely with the “Shut Down” command. This should be step 1 before removing the back cover screws. Also as noted all the back cover screws are Apple Pentelope #5 bit, but 2 of the screws are shorter than the others. This bit is is hard to find in most stores. Buy it on line along with the Tork #5 and #8. 11/21/2017

Replaced my Magsafe 2 yesterday and it works perfectly on my MBP 15” ea13. However, when I plugged in the charger I heard the startup sound twice and then I got to the login page where I realized the keyboard didn’t respond.

So I thought I should restart the computer so I clicked ”shut down”. But the keyboard is dead. I can’t start it. I haven’t tried to use a USB-keyboard yet..

Any ideas what may have caused this to happen and what component ”handles” the keyboard? Thanks

Not sure if this has been listed.

PRO TIPS from a non-pro:

1 - Keep screws separated and labeled by step # and size.

2 - Be very careful to get screws in properly threaded, its VERY easy to strip the ccrew holes and screws. Especially the case. Not that it happened to me…

3 - It was impossible for me to get all the adhesive off the case from under battery, it left a lot on w/o issue (yet).

4 - Make sure you have Aluminium Foil before starting!

5 - Upgrade the SSD or HDD while your in there!

If you are following this how-to because liquid/coffee splashed in through the back vents, WAIT UNTIL THE END to clean any liquid spills on the bottom panel. Use them as your map for cleaning and QA guide for checking until you are finished with your cleanup of logic board and other items.

For rMBP 2012 Late, you don't need to remove this sticker.

Why is this step necessary?

67b5ebab Good question !

Why is this necessary ?

This step is necessary to prevent any discharging, arcing, friction/static charges from damaging any of the extremely delicate and intricate parts of this (or most any) electrical system. In practice, you should even be wearing an anti-static band or be working on an anti-static bench even with the battery disconnected so your body doesn't create any unintentional charges.

One of the first things you should learn in electronics repair and and electrical in general is to cut the power source whenever possible before performing any work. Some systems have schedulers/triggers set that will wake the system up (even when closed) to perform updates and other maintenance tasks as to not eat up CPU and RAM during 'peak hours'. The last thing you need is to have your $2,000 laptop turn on while pulling an SSD (which, correct me if wrong, isn't a plug-and-play based device) which could do some serious corruption and/or damage; when all you had to do was peel a sticker and plug.

Hope that helps!!

~the more you know~

I did not peel back the sticker. It is probably there to help unplug the battery. You can apply a gentle constant pull while you use spudger to lift the battery connector out of the socket as per the next step. It made this very easy.

Joel - the purpose of all of the trouble in removing the logic board is to make sure that you don’t damage anything when you start pull out the battery. After this step - it’s true, you have about 12 connectors and dozens of screws to unplug, but I didn’t have any major problems.

REASSEMBLY - I had to use alot of force to get the official IFIXIT battery connect to push into place to actually connect. I was worried that one of the wires would stress and break. It worked, but it was not super easy this part.

I also skipped down to step 50. I stuck a piece of 1/2 inch weather stripping across the middle of the top cover of the laptop to maintain a pitch on the unit so the adhesive remover stayed away from the other components. I applied the remover and used a piece of string to cut through the adhesive strips. I owed the plastic tool from the kit to position the string behind the top of each cell and cut through one ata a time. The battery came out in about 15 minutes. The directions were very informative and useful but I thought the risks associated with dismantling the laptop and reassembling it again were greater. I could not have done it without the details presented. Thank you.

Having broken a connector on a logic board in the past, I worried about all the steps. But I understand the disaster that can occur if cleaning fluid contacts the logic board. Weighing costs and benefits, I also did not remove the logic board. I loosened up the speakers (since only two screws could be removed) to give me space to slide the cards under the battery cells. Using the two cards, sometimes sliding one over the other, I was able to remove the battery in 15- 20 minutes. Removing the remaining adhesive was VERY tedious. Eventually I settled on CAREFULLY applying small amounts of remover with the syringe and using the spudger (both pointy and broad ends) to scrape the remainders off. I cleaned the residual with Q-tips dipped in remover (buy a big box of Q-tips), refastened the speakers, installed the new battery, closed the case and voila.

Question, on the first image above you can read a serial and other information ... The creator of the guide could you confirm if it corresponds exactly to the Apple serial on the box? I wonder why I had the laptop in assistance to replace the GPU, and other problems were born once I returned ... to which removed the cover I saw this sticker and I immediately had doubts about it.

I too found the need to completely teardown the laptop onerous and risky. I’m not certified in anything hardware but I’ve been doing my own repairs for a while. I watched the video referenced above and read the comments there. With some changes, here is what I did, which worked perfectly and minimized the risk, for a whole additional $3 in parts, just myself and in under an hour:

1. Go to hardware store and get 2 4” bolts ($1 each) and a coil of 20 gauage galvanized wire.

2. Wrap one end of the wire a few times around one bolt, then tie it off with a knot. Do the same with the other bolt, leaving about 10” of wire between the two.

3. Follow steps 1-4 in this guide

4. Slip the wire under one of the outer batteries (use a card or spudger to help get the wire underneath

5. Grip both bolts with one hand and rock them back and forth, pulling the wire under the battery, using your other hand to hold the case. This should take about 2 seconds (seriously). Repeat for other outer batteries

(continued)

6. Pull the plastic frames away from the left and right sides of the center batteries.

7. Repeat steps 4 and 5 for the two center batteries.

8. Jump to step 55, then reassemble.

Note: when installing the new battery, ensure the part closest to you is UNDER the two plastic tabs.

Worked perfectly.

Note: using the nylon thread with that much effort is crazy. Use the wire or fishing line.

i just got my Kit and started the procedure, i decided to try if i can get the bulged batteries out with a fishing line, which worked fine. No need to use any solvent and even not too much force was needed to get the line under the batteries. I was able to remove the batteries in about 5min, used another 10min to clean the case from the residue, and put in the new battery. All togehter about 20min of work. I´m very happy with the result, Macbook stays now back on its feet, closes correctly and trackpad works as expected.

Also departed from procedure immediately after STEP # 4 as per JOEL’s recommendation …used a small chunk of fishing line and it worked sans solvent…easily ! Spudger worked quite well to initially position the string /line & the ifixit ( ‘credit’ ) cards were nice for final dislodging of each battery segment from the last bits of residual gooey adhesive , AFTER working the fishing line back & forth down the length of the battery as much as possible. With the old battery out of the way, I used a razor blade to clean out the remaining bits of adhesive gunk. ( Decided NOT to use solvent here, either.) Took me every bit of 1-hour.

One thing that helped ,too, was a cheap pair of cotton gloves coated on the palm side w/ latex. This kept my fingers comfortable from the pressure of the fishing line & allowed more of a range of force …since I wasn’t wincing from saw-cutting myself !

If I am facing the MacBook like I'm surfing or typing, this I/O board is referring to which side of the MacBook? Left or right side? How about replacing the other side of I/O board? The other side I/O port are part of LogicBoard? If I want to replace it, need to replace the whole LogicBoard? TQ.

I damaged 1/3 of these litte guys, how did you get them back together?!

is there a way to replace the antenna?

unless you have really tiny fingers, a tweezer helps, just be careful not to damage the wires or the board as your holding each cable in place. Oh and take your time - this is like the most frustrating step in the process, imo.

The order of the cables doesn't seem to matter when re-attaching. It also might be helpful to unscrew and eject the airport card. Having it free can give you a better angle.

After reading so many reviews on ifixit and other sites regarding the difficulty of replacing my MacBook Pro retina screen assembly, I was a bit nervous. Using this walk through made it super easy. Thank you so much for taking the time to create it!

travismlive is right, you do not need to remove these cables or the airport card. Just remove the I/O board cable, undo the screws, and detach the antenna cables from the fan where they are glued with a spudger. Unlock the ZIF-socket and the you can wriggle the fan out. Probably saved my airport card, thanks travismlive!

I only successfully reattached 1 of the 3 AirPort cables, I just taped the other two. But the AirPort seems to work fine. Do these also have anything to do with Bluetooth though? I do seem to have trouble with Bluetooth after this operation. In any case, it was worth it... I replaced the screen with a new Apple screen for less than 1/2 the Apple Store wanted! Thanks!

Would soldering them back in place be better than taping? I certainly don't want spare solder on my motherboard, so I figure that'd be a last resort only if I lose AirPort connectivity.

Assembly is a nightmare. If rightmost cable is not connected, BT will not work.

the hardest step is reconnecting the airport antenna cables. just have patience< and use tweezers, spluger and a q-tip.

The three cables have different lengths. The longest should to the farthest pin, medium to middle, short to nearest.

Also, having the right tools will make the job really easy. I used a spudger similar to the one recommended on this web site. But i had ordered a complete kit from amazon.com. I did not have any problem removing or re-attaching the pins.

tweezers to hold the cable and the flat part of the spudger to push down on the connectors is the easiest way to re-assemble

Use leverage with tip of a spudger, it’s not that difficult to pry the cables.

When you reassemble, use a tweezers to put the connector on the right position and push it down with a finger on the other hand.

Grab the neck of the cable when using a tweezers.

Several of the people above mentioned not disconnecting these three wires. You must remove and replace these if you are replacing the entire display which is what these instructions are about. This is the most difficult step as others have noted. Just be careful and make sure you have the cable level before you start pushing down.

If you are not replacing the display case assembly, you can opt to leave all 3 connectors attached and remove the Airport card with them connected. You will need to carefully manage the card and attached cables so as not to damage them(masking tape) as you proceed with disassembly/reassembly. Step 6 will need to be done carefully (camera cable connector). I did it after step 8. I took a picture of routed cables as well before I removed them from channel.

Reassembling: What makes this so hard? From all appearances I’m just pressing a squat sleeve-and-pin connector down onto the female counterpart. It appears to be circular and therefore not needing to be oriented radially in any particular angle. It doesn’t look hard at all! Does anyone understand what the subtlety is that causes everyone so much grief?

Reassembling: as so many as commented, this is incredibly hard - and inexplicably so. From all appearances I’m just pressing a squat sleeve-and-pin connector down onto the female counterpart. It doesn’t look hard at all! But I couldn’t do it.

Here’s what seems to have worked for me: with my left fingertip on the cable holding the connector directly above the female, I used the spudger to press down the flat back of the connector, initially at the top and then sliding along toward the neck. I used normal pressure, and voila, when I lifted the spudger away the wretched wire didn’t spring up again. It was like it wanted to be rocked, or stroked, once, from top to neck, rather than pressed straight down.

I skipped to step 34. Just pushed up the speakers so that they don’t touch the body.

I totally agree, this step is not tagged contrarely to others while it is the most dedicate !!! 1/ A warning should be added (the 31 comments should have done it…) 2/True it is possible to skip this step. Result for me : 1/3 damaged (the left one). Luckily, everything seems to work airport, bluetooth (so far, I haven’t tried Airdrop yet). Really disappointed by this guide is way below the iFixit’s standard…

If you are removing the right fan it is not necessary to unplug the camera cable. You can slip the fan out underneath the cable.

Hi! Camera flex cable is from MBP Retina Mid 2012 & Early 2013. Not Late 2013 :) Edit it please.

Push on the little wings, from right to left.

This is the hardest part of disassembly! Arguable hardest part of re-assembly too, other than the airport cables

The instruction is not clear to me at all. Frankly the comments mentioning things make me uneasy about proceeding further.

This came off for me - now my computer’s fan is running high constantly, and “Kernel_task” is using 500% of the CPU even though nothing else is running - what can I do?

It is very important to note here that you are NOT pushing up. You are pulling the cable back toward the fan. Doing step 7 first makes that easier. I misunderstood the instruction here (as others seem to have as well) and broke this part. I’m fine with not having a camera on this computer so I’ll leave it or ask my son to help me solder it later.

The wing closed to the edge of the chassis is completely stuck. I’ve worked on it for an hour. The other wing moves freely. I’m not sure what to do now.

The connector is very tight - I couldn’t even see the join between cable end and the socket and couldn’t see the “ears” on the end of the socket. And, of course, pulling didn’t help. I eventually used tweezers to start things off, gripping on the metal of the socket right where the invisible join was. What a delight to have the join open enough to see! After that, it was easy.

Thank You Jerryl - The tweezers did the trick. They want to pop out so you can use your other hand to apply slight downward pressure to keep them in place. Work both ends of the tweezers gently back and forth and you should start to see the gap get bigger.

Back (case) side of rubber attachment is flimsy-ish, so need to be delicate when peeling rubber back.

It's a bit tricky to re-route the cables when you're installing the new display, so pay close attention to how they're originally routed, to make sure you don't pinch them or torque them.

Do we need to use some adhesive to paste them back?

I used scotch tape to temporarily hold the cables in place until I was ready to reinstall the bottom cover, but I removed the tape at that last step (didn’t want it coming loose later, and possibly obstructing a fan).

Note that the Mac has been rotated 180º between steps 8 & 9

When reinstalling the io board cable make sure it is the correct way round as in the photo, it fits the wrong way round as well, which results in the MacBook not starting at all.

Sockets are ZIF with releasing levers on the top. If you pull up on the top padding, you will reveal silver lever handels facing the rear of the machine. Pry up on the LEVER to release the pressure, then pull the lever straight up to release the connector from the socket. DO NOT pry under the edge of the connector to remove these or you may damage the ZIF socket. They may have changed these connectors between models, otherwise I don’t know how this was overlooked in the guide.

As others have mentioned, it's not necessary to remove the Airport antenna cables. Leave the cables attached and remove the Airport card.

Swing the card and the attached cables across the fan.

You may lift a little like few degrees then pull parallel when removing.

There might be a touch of adhesive, lift first – a gentle touch with the spudger helps.

Yes, lift about 5-10 degrees first, then pull out. If you do not release the adhesive, it may be stuck in place and you could damage the card trying to pull it out.

I was able to flip the retaining flap while removing the damaged fan but accidentally dislodged after installing the replacement fan. Again, be very careful at this stage. Thankfully my new fan appears to function normally.

Easier to do while removing fan.

The second picture and illustration are not clear enough. The text should say "pry underneath the cable" as I almost broke the fan cable following instruction.

ZIF = Ziero Insertion Force. Once the tiny retaining flap is up, it should slide out easily toward the back. There was no adhesive on my machine, so the cable slid out easily. But be careful if yours is glued down.

I don’t know why, but I could pull the connector out & in without flipping up the flap. And fans are working flawlessly.
