Introduction

Use this guide to replace a faulty logic board in your MacBook Air 13" Early 2015.

Be sure to apply a new layer of thermal paste before reinstalling your heat sink on your new logic board.

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

  • Remove the following ten screws:

    • Two 9 mm P5 Pentalobe screws

    • Eight 2.6 mm P5 Pentalobe screws

  • The special screwdriver needed to remove the ten 5-point Pentalobe screws can be found here.

These pentalobe screw sizes can't possibly be right - not even close. Should they perhaps be 0,8 mm and 1,2 mm?

Rulle Boer - Reply

The screw sizes refer to the length of the shaft, not the diameter of the head or socket. P5 is the standard pentalobe size for all these screws, regardless of length.

I agree that the notation is a little confusing. I think it's because, with standard sized hardware like for your house, you have shaft diameter (say 1/8" or 3mm) and shaft length (say 3" or 7.5cm). So we're programmed to think of small numbers like that as diameter. But in this case, they're length.

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!

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.

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

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 toward the front edge of the Air to disconnect the battery from the logic board.

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.

Hi, I messed up the socket, is there a replacement for the socket that holds the fans wire.

When handling the battery, avoid squeezing or touching the four exposed lithium polymer cells.

  • Lift the battery from its edge nearest the logic board and remove it from the upper case.

  • If you're installing a new battery, you should calibrate it before using it: allow it to drain overnight, then charge it to 100%. Let it continue charging for two more hours, then drain it again until your MacBook Air shuts down automatically. Charge it again and use it normally.

    • On some models these may be 4.1 mm T5 Torx screws.

When re-assembling the motherboard, attach all 6 screws but do not completely tighten yet.

First make sure the rubber gasket is sitting properly, that the 7th screw hole (from Step 18) is properly aligned, and the Airport wire is sitting properly and also not caught under the heat sink.

Once everything is well aligned, start tightening the screws while watching out for the alignment. I found it useful to keep an eye on screw-hole from Step 18 as a reference.

Going in this order, there is a 7th screw securing the logic board to the frame; the heatsink is secured to the logic board with 4 screws, and secured to the frame with 1 more screw. Either take the heatsink off first, or remove that last screw underneath two small black wires, next to the left (as viewed when using the computer; if the computer is flipped over with the cover off and the monitor hinge end of the computer farthest from you, it is in the far right corner) set of three big torx screws that hold the hinge in place. The exact location of this screw is pictured in step 35's second picture; the screw goes through the loop visible below the rubber fan insulator. Scoot those 2 li'l wires out of the way and remove that screw, then the logic board comes right out. If this isn't clear, please let me know and I'll try to describe it better, or add a photo. If I'm posting this to the wrong instruction page, let me know; I was pretty sure I correctly identified my rig, but if not, sorry for the N00bage.

I got an extra screw hiding under the rubber gasket holding the end of the heatsink to the chassis. Ended up bending the heatsink a little cause I wasn't looking for it.

In both the online and the PDF version, Steps 17-18 and Steps 29-30 are identical. At which stage should you actually remove the display screws?

  • If the heat sink seems to be stuck to the logic board after removing all four screws, use a spudger to carefully separate the heat sink from the faces of the CPU and GPU.

  • Remove the heat sink from the logic board.

  • When reinstalling the heat sink, be sure to apply a new layer of thermal paste. If you have never applied thermal paste before, we have a guide that makes it easy.

When reassembling your device, be sure the heat sink's rubber gasket is installed correctly. The nub on the gasket should mate with the hole cut into the logic board near the heat sink fins. The tail of the gasket should fit into the notch in the heat sink, it should not end up underneath the heat sink tab that will rest on the logic board. Make sure the antenna cables are inserted into their respective notches on the logic board, as highlighted in the last picture.

This step is REALLY helpful. I skimmed over it when disassembling and then struggled a bit trying to get the rubber gasket aligned just right.

The middle photo shows what I mean, it's exactly what I needed.
