Time Required

30 minutes - 1 hour

Introduction

Use this guide to replace your Air's I/O board which houses the MagSafe DC-in port, a USB socket, and the headphone jack.

    • Before proceeding, power down your MacBook. Close the display and lay it on a soft surface, top-side down.

    • Use a P5 Pentalobe driver to remove ten screws securing the lower case, of the following lengths:

    • Two 9 mm screws

    • Eight 2.6 mm screws

    Pulling the fan cable out was terrifying but you actually just pull on the cable itself. No way to get any leverage at the connector to dislodge it. Did come out easily but like I said, scared me!

    Draai de schroefjes voorzichtig los en leg ze op een stabiele plek neer en let erop dat de schroefje een verschillende lengte hebben.

    Do you have good Test Point Voltages? It appears there are silver colored Test points on the I/O Board. I am working on a water spill and trying to troubleshoot if both the I/O board and the Logic need replaced.

    andrew -

    It's probably not necessary but may be a little safer to completely discharge the old battery before replacing it.

    Larry Smith -

    tell a model that was not inferior to the speed of the one in the laptop.

    Thank you

    ilyabuhov -

    Do i need to order tools separately to replace the battery i just ordered?

    im looking for a Logic Board for a

    Apple - MacBook Air® - 13.3" Display - Intel Core i5 - 8GB Memory - 128GB Flash Storage (Latest Model) - Silver Model: MQD32LL/A

    Any help is appreciated.

    P5 pentalobe screwdrivers are too big! The correct size for these screws are p4 pentalobe. P5 pentalobe was just able, with difficulty, to turn some of the screws. If the screws were at all tight, my p5 was unable to get them out, and started to strip the screws. A p4 screwdriver fit better and removed the screws with ease. (I was using high quality Wiha brand screwdrivers.)

    William Skinner -

    I had same experience (with MacBook Air 13-inch Mid-2012) … had to get P4, which worked swimmingly

    eric -

    Very simple installation. The screwdriver heads were exactly what we’re needed, one head for the outside case screws, the other for the screws holding the battery in place. The computer started right up. Now to see how the battery holds up, but I have a good feeling about this!

    Dennis Eaton -

    My P5 and the T5 worked perfectly with my early 2015 Air 13”! And it is super fast! Thank you iFixit!

    Pennny Beach -

    The supplied kit and instructions worked perfectly!

    Nikolay Andreev -

    Comments that the P5 pentalobe are too large are absolutely spot-on. There is no way the P5 pentalobe bit I have will work with the MacBook Air without destroying the screws. Hard target search for P4 pentalobe bit in progress…..

    joemoog -

    Bonjour j’aimerais changer mon SSD de 128 Go pour en mettre un de 512 Go. Je ne sais pas ce qu’il faut prendre car il faut qu’il soit compatible avec le macbook air A1466. J’aurais vu un Samsung Evo 970 500 Go mais si je ne me trompe pas, il faut un adaptateur.

    Merci pour votre aide.

    chicco33 -

    oui, vous aurez besoin d’un adaptateur, pour completez le changement.

    Dan -

    The tool kit should include tweezers for re-inserting the battery connector.

    Andre Clement -

    P5 pentalobe worked perfectly for me. Instructions were spot-on. Antenna connections were a bit fiddly to refit but got them in ok.

    michaelquinnell -

    Maybe the problem some are experiencing is that the designations are confusing (blame Apple rather than iFixit). the P2 is also known as PL1. The P5 is also known as PL4. The P6 is also known as PL5. So it is possible to mistake the P6 (PL5) for the P5 (PL4), meaning it (P6-PL5) will be too big, while the P5 (PL4) will be just right. Sort of a 3 Bears explanation, but it is very confusing.

    Thomas Lewis -

    To add to this. In searching for the P5 screwdriver to buy in UK, as far as I can tell, it is also known as

    Pentalobe 1.2(mm)

    also

    P4 = 0.8

    P6 = 1.5

    Just unscrewed the back case of MacBook Air 13” mid 2011, with no problems using Pentalobe 1.2

    nijafe -

    I have not replaced a display on the A1369 but have done many A1466 which is a newer 13” model. They seem really similar and its not clear why one needs to remove the logic board to remove the display. The antenna cables on the A1466 dont have to rest under the logic board but can be tucked in the hinge crevice. Cant this same thing be done with the A1369?

    Sean Love -

    Did mine today - but new battery wasnt charging. Went back in and noticed the battery connector cable was not quite 100% “seated. It was sticking out by less than a millimetre! - you need to give it quite a firm push in to get it seated properly. Otherwise - all ok .

    John Brennand -

    Just installed on a MacBookAir6,2 (13-inch, Early 2014).

    Was very easy.

    New iFixit battery looks great so far:

    Full Charge Capacity (mAh): 4922 -> 7333

    Jonathan Cross -

    can you tell me which size of screwdrivers you’ve used to crack it up, please? I have the same model and size,

    hawk_lpc -

    Screw P5 Pentalobe 1.2

    Mario Verlent -

    Install went flawlessly. Only challange was reattaching blue tooth antennas. Those sockets are so tiny.

    Joel Sebastian -

    Installation was a little challenging at first because the instructions on this site did not perfectly match my model (late 2013 to early 2015).

    Found this video on YouTube which described the procedure perfectly https://www.youtube.com/watch?v=Lue6lVWh...

    Also the Ifixit kit I received was well put together with everything I needed and more. The calibration went perfectly and I am very pleased. Will buy again!!

    Donald Niamath -

    Gently pulled out connector of old battery, then pressed and held the power switch for 1 minute. Unscrewed and removed the old battery. Pressed and held power switch for 1 minute again. I know from previous work that this helps drain charge from spontaneous recharging as the dielectric recovers. Gently “fine tuned” leads from new battery to connector till connector stuck out at right angle to the edge of battery. Held the battery by the edges and let the connector slide into the socket. Set the battery down and put the screws in all the way. Then checked that the connector was completely seated before tightening the screws. The laptop come on immediately and showed 98% charge and registered normal (checked in “About this Mac”. Very happy to this point. Now for calibration.

    Amir Zaidi -

    Thank you very much for the guilde. My MBA2011 had reborn !

    Billy Wong -

    Allow for electrostatics, otherwise you may cook components on the logicboard /motherboard (like I did with one of these!)

    See great advice: Electrostatic Discharge

    IFixit just had me submit "my story" re. fixing my MacBook Air 2013.

    This repair was NOT difficult. The battery is enclosed in a plastic frame. It is NOT glued in like the newer models of Apple laptops. And unlike older laptops, the battery is not totally enclosed in a plastic housing. So once you remove the screws holding the batterie's frame, you can remove the battery.

    Follow the instructions. Read the comments. Also read the comments re. installing a new battery.

    Good luck. - Eric J.

    ECJohansen -

    On the back of the laptop, notice that each screw is angled a little bit inward, aiming toward the middle of the laptop. Keep your screwdriver lined up with the screw (angled a bit outward as seen at 01:23 in the video: https://youtu.be/tToAwO6f-SY&t=83). This will help you get a good bite on the screw to get it out and avoid stripping the head of the screw.


    Use the same angle when putting each screw back in. If the screw is in line with its hole it should not feel like you are fighting to screw it in. If it does, check your angle and back up a little; you should feel the screw fall into line.

    • Wedge your fingers between the display and the lower case and pull upward to pop the lower case off the Air.

    • Remove the lower case and set it aside.

    There is a nub on the inside of the case which is attached to the battery. When you try to pull it open, it appears to be attached to the plastic casing of the battery, which sometimes splits. I gently unhooked the nub from the battery before removing the case fully. This seems to happen if the battery has suffered some drop damage (plastic parts broken around screws and parts of plastic frame split). Just an FYI in case your lower case doesn't pull away easily.

    Jeannie Crowley -

    To add - the slim 1cm tab “nub” is on the centre of the back cover & fits into a hole in the battery frame. I ran my fingers around the whole of the cover to eventually here it click out.

    nijafe -

    When closing this back up make sure that the antenna cable is tucked away neatly

    Gabriel -

    So this is a legit back cover for MacBook Air?

    ASHANTI SMITH -

    What about disconnecting the battery?

    Luke -

    I bought the part and tools from iFixit and followed the directions. The mechanical part went smoothly - maybe 10 minutes to disassemble/replace/reassemble.

    Getting Catalina (the current MacOS) to install was not working until I used Cmd-Opt-R (as noted in the OWC paper sheet that came in the box) which brought up the proper installer - I believe from a pre-prepared bootable SD card but it’s hard to say. From there the install succeeded taking ~1.5 hours.

    Beware that (a) the install requires a working internet connection for verification and updates, and (b) the system must have been running at least macOs 10.13 (High Sierra) before the install in order to have an EFI BIOS that recognizes the SSD.

    Lance Berc -

    As noted by others, be a bit careful removing the lower case. There is an oblong black plastic locator very near the center of the lower case. Unless you gently pry the bottom cover pretty much straight up, you will break the ends off of the locater.

    BobY -

    Thanks for the detailed photos. When repairing equipment, I don’t really like to disassemble plastic parts, they can be damaged, but your screenshots help a lot. For my studies, I am writing an essay comparing the reliability of laptops from various manufacturers and the complexity of their repair, maybe it will be useful for someone to check the essay for plagiarism here essay checker, when comparing different manufacturers, I understood why people love Apple so much. The minimum number of failures. Of course, repairing it in an official service is not cheap, but with the help of such detailed instructions, you can do it yourself and save a lot.

    Nexus -

    The screwdriver bit to use on these case screws is not named, but I found that my "CR-V 1.2" did the job nicely.

    The driver for the screws inside the case are named, as "T5".

    • As a precaution against accidental discharge or shock, disconnect the battery connector from the logic board.

    • Grab the clear plastic pull tab attached to the battery connector and pull it toward the front edge of the Air to disconnect the battery from the logic board.

    • Be sure to pull the connector horizontally toward the battery, and not straight up from the Air, or you may damage the socket on the logic board.

    The clear plastic tab is missing on mine. Whoever worked on my laptop before me seems to have ripped it off. Now what?

    mjmorawski -

    My plastic tab pulled off the connector. I worked the connection apart using two spurgers, slowly backing it out side to side.

    • Use the flat end of a spudger to pry the I/O board cable connector upward out of its socket on the I/O board.

    Be really careful when reconnecting the I/O board cable connector. The deep connector has a tendency to bend the pins with very little force applied. If this is the case, check to see if the gold pins are bent down, you may only see one row of gold pins vertically, or none.

    They can be lifted with a flat head screwdriver bit. Gently slide the bit under the pins, this may need a small amount of pressure depending on how far they are bent down. Lever the pins back to the vertical position.

    I found attempting to insert this connector was easier while holding the MacBook on a slight angle to see down the pins as I aligned the connector.

    Another way to tell if the I/O connector cable is in place correctly is to run an Apple Hardware Test. Hold down the letter D while booting the mac and follow the prompts. If no issues found, you're all good.

    A common error for a misconnected I/O Connector is 4SNS/1/C0000008:TS0P--124. This means the system cannot read the palm temperature sensor. Fix the cable and you're good

    Ben -

    Hi, Can the 13” Logicboard of 2012/2013/2014 or 2015 be compatible in the 2011 model?.

    verma1986 -

    This is ridiculous.

    From this point, skip ahead to step 18. There is no need to perform steps five through 17.

    I am glad I saw your comment. This saved me a lot of time and allowed me to miss many points of failure. thanks.

    • Carefully peel the I/O board cable from the top of the fan.

  6. yctMokPOfrNwiZAf

    • The following connector has an especially deep socket. Use care when disconnecting it.

    • While gently pulling the I/O board cable upward near its connection to the logic board, use the tip of a spudger to pry upward on alternating sides of the connector to help "walk" it out of its socket.

    • Remove the I/O board cable.

    This step can be skipped, not required for removing the fan.

    yurkennis -

    Agreed, there is no need to remove this cable.

    David Robillard -

  7. xGDACPNg6taXS3GW

    • Use the tip of a spudger to carefully flip up the retaining flap on the fan cable ZIF socket.

    • Be sure you are prying up on the hinged retaining flap, not the socket itself.

    It is not necessary to remove the fan cable.

    ezequielaceto -

    It's certainly necessary to remove the fan cable, as you won't be able to remove the fan in Step 10 if you don't!

    Goth70 Fuzed -

    If you break the ZIF socket, it could be a bad day.... It happened to me. Not one to throw in the towel, I fashioned a hold-down with a length of paperclip held in place by the nearby screw. So far, it is working like a charm. Hopefully, it continues to work and this helps some other poor soul.

    Lester Newsom -

    I also haven't removed the fan cable. No need for this step IMHO. Just let the fan on the side instead of completely remove it.

    David Robillard -

    Trouble putting the cable back in the ZIF socket?

    Get some electrical tape and cut it down the the width of the ribbon cable fold over one end to create a pull tab. Now place the tape onto the ribbon to give yourself something to pull either in or out as needed. Then you can peel off the tape.

    Don't forget the unlatch the connector first!

    Source: Re-connecting fan ribbon cable

    Adam Banko -

    The hardest part is to put the fan cable back in the ZIF socket.

    (Why do people say you don’t have to unplug the cable? that makes no sense)

    Digital Blended -

    after putting the cable back in the fan is very loud, can someone help?

    Ramon majem -

    Be very careful when locking the ZIF connector during reassembling. This was my first time seeing a ZIF connector, the retaining flap plastic bounced when I was reassembling the I/O board ( I didn’t pushed so hard though) and a struggled nearly 1 hour to reassemble it. Same connector, be careful. It was a nightmare, thank god it didn’t broke!

    Berkin Birol -

    Quick note, when u install the new fan, i inserted the ribbon cable back in the zif socket first with a pair of tweezers then screw the fan back in.

    robdroby -

    I see comments suggesting not to remove the ribbon cable. This would work. Simply flip the fan like the page of a book, from right to left, thereby getting it out of the way while you remove the i/o board. Flip it from left to right when you reinstall. This approach would save some frustration, as it is a challenge to reinsert that tiny ribbon into position.

    If you do remove the ribbon, reinsert it before repositioning the fan. That will give you more play as to fiddle with the ribbon.

    • Peel the rubber gasket off the adhesive on the top of the fan.

    Note how the “ears” of the gasket are routed

    davecortesi -

    Where can I purchase a replacement gasket? It’s missing after the repair place opened my computer

    Erin Kaspar-Frett -

    Should I put some adhesive back when reasembling?

    Marco -

  9. JkFbWGVELGUa3sDJ

    • Remove the following three screws securing the fan to the upper case:

    • One 3.6 mm T5 Torx screw

    • One 2.7 mm T5 Torx screw

    • One 3.6 mm T5 Torx screw with a short head

    So far great

    Joseph Sperber -

    When reinstalling, start all three screws before tightening down. There’s some play in these holes, and you will have trouble lining them up if you tighten one down first.

    Curtis Kline -

    I just replaced the the i/o board and it went fine, but I think I broke the screw holder on the top left side of the fan, and now can get the screw out - the computer still runs - i was wonder can I get a way with that one screw not holding it down?

    ilarkin1 -

    Same here. The screw socket was broken for the 2.7 mm T5 Torx screw. Is there a way to re-solder the socket? Or support the fan. It’s making a horrible noise now :(

    Jason -

  10. WJylrjPZcYcgBDKb

    • Lift the fan out of the upper case and carefully pull the fan ribbon cable out of its socket as you remove it from the Air.

    Would like more detail about removing the fan cable. Looks like it just pulls out to the right. I thought I ripped it off.

    kennyavis81 -

    On re-installation of fan cable cable no tool required - just wiggle it in from from side/above (side force aided by bend of cable)

    Super easy - my first computer repair..hope all is well

    paul deacon -

    The ribbon connector held in the socket by a tiny square on top, which enters a square hole in the top of the socket. An xacto blade used to pry the top of the connector gently up will help release the connector.

    peteragries -

    This helped me no end, I agree with the people above that it's worth explaining how the ribbon cable is held in and that

    it's simple to remove and reinstall. Thank you for a brilliant guide.

    leesparey -

    Year, from the top, the ribbon appears to be just the plastic strip. Copper connectors are on the bottom but at first glance it looks like I pulled the connector off the ribbon. Mine pulled straight out away from the connector, no upward angle needed or desired.

    Allen -

    Question: Is the ribbon connector a part of the fan, so that the new fan has its own ribbon connector? Apologies if this sounds trivial, but I could not tell from the wording/picture.

    jerry bennett -

    So I did the replacement according to this guide, with a replacement fan purchased from iFixit, and the fan would not spin even under heavy load! I took out the fan, and noticed that there was quite a lot of resistance when I spun the blades manually. It turns out, the fan was slightly squashed flat near the vent so that the resulting friction prevented the blades from spinning free. I un-squashed the fan, re-installed it, and the fan is spinning! The moral of the story is to make sure the blades can spin free when installing a new fan.

    Hiroshi -

    On reassembly, I found it hard to reinsert this ribbon cable, so did step 11 again. I disconnected the I/O board, connected the fan and snapped the retainer down on the ribbon cable, then undid step 11 (ie. I connected the I/O board again). As others have said, a brilliant step-by-step guide, and slloeing comments is a great idea too.

    Jim Henderson -

    nice! Congrats!

    • Disconnect the I/O board by pulling the power cable away from its socket on the logic board.

    • Pull the cable parallel to the face of the logic board toward the right edge of the Air.

    You can skip the following five steps if you are just trying to remove the logic board—the I/O board can stay put, and it won’t hinder logic board removal.

    Jeff Suovanen -

  12. YgRIQGX3DxVNH2JH

    • Pull the camera cable parallel to the face of the I/O board toward the hinge of the Air to disconnect it from its socket, using the tip of a spudger to help push the connector out of its socket.

    • Do not lift upward on this cable as you disconnect it, as its socket may break off the logic board.

    Use the corner of the flat edge of a spudger to push alternately on the metal ears to help disconnect the cable.

    peteragries -

    And when reinstalling, push the metal ears from behind to snap the connector back into the socket

    peteragries -

    In my model (model identifier: MacBookAir6,2), the camera cable connector was found located on the logic board.

    Kuro Kurosaka -

  13. T2dHcBpelkhnPwTe

    • Use the flat end of a spudger to pry the left speaker cable connector up and out of its socket on the I/O board.

    • Pry up from beneath the wires.

    Don’t use a spludger!!!!! Use tweezers or a super thin flat head. Spludger is too thick…

    Jared Thiel -

    Well, dangit. I used a spludger, and now I’ve got two gold wires just hangin’ out. Think it’s salvageable?

    jeff elrod -

    If you have 2 ‘gold wires’ hanging out (assuming that you’re referring to the connectors and not bare wires!), you’ll have to inspect them under ‘high’ magnification (40x loupe would do) and make sure the tabs are propped out so that when you plug them back into the connector they’ll grab the connector (and don’t slip out when you attempt to plug the connector in). Inspect the connector to see what orientation to insert the connector plugs in. Mate the tabs on the plug with the surface opening on the plastic connector housing.

    anonymous 6745 -

    I used a pair of tweezers. One (tweezer) end under the plastic connector, then squeezed the other (tweezer) on top of the plastic connector. Gently wiggled up and down and the connector easily popped out.

    • Use the tip of a spudger to flip up the retaining flap securing the microphone ribbon cable to the I/O board.

    • Use the tip of a spudger to remove the volume button ribbon cable from its ZIF connector on the I/O board.

    This is throwing me for a loop. It won't fit back in. Are the volume and mic cable the same cable?

    david nieto -

    Use the tip of the spudger on the plastic ear at the back of the connector (the ear is on the battery side), to push the connector out of the socket.

    peteragries -

    This step (14) appears to use two different names for the same cable: microphone ribbon cable and volume button ribbon cable. This is confusing because the photos appear to show only a single cable being disconnected from a ZIF socket.

    sjosefw -

    Be very careful when locking the ZIF connector during reassembling. This was my first time seeing a ZIF connector, the retaining flap bounced ( I didn’t pushed so hard though) and a struggled nearly 1 hour to reassemble it. It was a nightmare, thank god it didn’t broke!

    Berkin Birol -

    I found it was easier to perform removal of the cable until step 16 when I was removing the I/O board.

    Mark Kilpatrick -

  15. 2fMNnpvKjLZWIw1W

    • Remove the single 4.0 mm T5 Torx screw securing the I/O board to the upper case.

    On reassembly, it's good to line up the screwhole in the corner of this board with the hole below it, so the fan screw can be replaced properly.

    Jim Henderson -

  16. BZkpAxpCrTaGoVKZ

    • Carefully lift the I/O board from its edge nearest the logic board and remove it from the upper case.

    Be careful when reassembling the I/O board. The USB and headphone jacks should be oriented well, otherwise USB dongles won’t fit even if it looks well adjusted.

    Berkin Birol -

Conclusion

To reassemble your device, follow these instructions in reverse order.

Where can I buy the 2012 I/O board?

Andrew -

I bought a used I/O board on ebay for $30. Replacing the i/o board solved my problem with the "fan stack" heat sensor which had been unreadable and causing the computer to run very slowly and the fan to run full speed. It was listed like this:

2012 13" MacBook Air MagSafe II DC audio I/O Power Board A1466

fornext -

HELP NEEDED PLEASE !

While removing the Board I torn apart the pièce at the end of the cable (linked to side) on the l'est of the lasr image. What is it and Howard Can I remplace it ?

Sasha Baba -

The is a connection that is near the middle outside of the board (near the wifi card) and it looks similar to the I/O connection. Would anyone be able to identify what that connection is and what it is for. I have a 2012 MBA and I wondered if it is a PCIe connection that is unused???

Andy -
