Introduction

Use this guide to replace the I/O board.

    • 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.

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

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

    Thank you

    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.)

    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!

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

    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…..

    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.

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

    • 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.

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

  2. To ensure that everything is de-energized and won't turn on while you're working, it is recommended that you disconnect the battery. Grab the clear plastic pull tab attached to the battery connector and pull it parallel to the board toward the front edge of the Air.

    • Do not lift upward on the connector as you disconnect it or you risk damage to the connector socket.

    after disconnect the battery, press and hold 5*10 seconds the powerbutton on your keyboard to unload the capacitors

    When putting this back together, be careful you don’t flip I/O board cable. It will fit, but the computer will not work. You’ll know it’s wrong if it covers the fan.

    • Carefully peel the I/O board cable from the adhesive securing it to the top of the fan.

    • During reassembly, make sure this cable is in the correct orientation. It will fit if reversed, but the laptop will not boot.

  5. 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 flat end of a spudger to pry up on alternating sides of the connector to help "walk" it out of its socket.

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

    I did not find it necessary to loosed the retainer flap, unplug the ribbon cable from it's socket, or remove the fan. After removing the fan screws in Step 9, the fan was loose enough that it can be slightly moved to the side. I felt that loosening the retaining flap and removing the fan adds unnecessary potential to damage something. To the contrary, if you bump the fan while it's plugged in, you might damage the ribbon cable.

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

    In my case the adhesive had already come undone through normal use.

    • 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

    I found it easier to do step 11 before this one.

    During reassembly don’t forget the ribbon cable.

  10. Lift the fan from the I/O board side and pull it free from the upper case. Removing the fan will also disconnect the fan ribbon cable. Be careful not to snag it.

    It is a lot easier to insert the flat ribbon in its socket before placing the fan back in place. BUT DO NOT YET FLIP BACK the retaining flap, until you have seated and screwed the fan. This way in case you pull on the fan by mistake, the flat ribbon is free to come out, otherwise you may tear it.

    • Disconnect the I/O board by pulling its 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.

    Steps 12 through 16 are not really necessary; you can easily de-route the necessary cables without removing the I/O board. Likewise with reassembly.

    When following these steps in the reverse order to reassemble the machine, I found it much easier to insert the ribbon cable before inserting the I/O board into it's place and installing the screw (Step 14). This adds potential for any sudden movement to damage the ribbon cable, so gentle care must be exercised.

    Tried doing both ways when reassembling but the ribbon cable is so crimped that it won’t feed through the socket anymore. Not sure how to get it through else replace cable or run without a microphone.

    I also noticed that the ribbon cable has a “tab” of extra ribbon above it that was hard to see in the pictures.

    I didn't actually need to remove the IO board, it's enough to remove the screw to let it loose. Therefore also step 12 and 13 are useless.

    THANK YOU. Was able to push the camera cable under the io board without removing it.

I did this as my first DIY repair inside a MacBook. I'm pretty handy, but nothing close to a computer tech. I studied the guide a few times; ordered the Pentalope driver; bought a magnifying hobby light; set up an organized workstation and went to work. I did sweat through several of the cable and ribbon strap removals, but if you take your time and follow the guide it should work. I did find that having a set of precision tweezers and a couple of plastic spudgers was extremely helpful.

My need to attempt this was the result of stupidly spilling a beer all across my keyboard. After drying it out via a fan blowing on it 24/7 for 2 days I decided to crack it open and look for water damage to the LSI's . The area that appeared to be hit the worst was the I/0 board. So I removed it & cleaned with Isopropyl. Afterward, everything fired up and seemed to work fine. Until today. Now the left USB port seems to have died. Probably will replace the board. This guide made it possible. Thanks Jeff and Ifixit.

Very precise guide. I’d say I had this apart, the new board in and put back together in about 30 minutes. like stated above, take your time with some of the more delicate cables and you should be fine. Thanks Jeff.
