Introduction

Use this guide to replace a damaged logic board.

Image 1/1: Remove the following ten screws:
  • Shut down and close your computer. Lay it on a soft surface top-side down.

  • Remove the following ten screws:

    • Two 8 mm 5-point Pentalobe screws

    • Eight 2.5 mm 5-point Pentalobe screws

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

When you say:

Remove the following ten screws:

Two 8 mm 5-point Pentalobe screws

Eight 2.5 mm 5-point Pentalobe screws

Do the 8mm & 2.5mm dimensions refer to the LENGTH of those screws, or the size of the pentalobe? That is, are there other sizes of pentalobe drivers like there are for hex, phillips and torx? When only one dimension is provided, it is usually the socket/driver size, not the screw length, maybe since the length cannot be seen when the screw is installed.

Can I suggest that you clarify your instructions so folks are confident they are only in need of _one_ pentalobe driver?

Nerdily yours,

The 8mm and 2.5mm are the length of the screws. One pentalobe P5 screwdriver suffices for all the screws (P5 is implicitly the size of the pentalobe screw heads).

I sourced all the parts from ifixit, plus a magnetic project mat which I found to be very useful for organising the teardown and reassembly.

Image 1/2: Use the flat end of a spudger to pry both short sides of the battery connector upward to disconnect it from its socket on the logic board.
  • In this step you will disconnect the battery to help avoid shorting out any components during service.

  • Use the flat end of a spudger to pry both short sides of the battery connector upward to disconnect it from its socket on the logic board.

  • Bend the battery cable slightly away from the logic board so the connector will not accidentally contact its socket.

  • Remove the single 2.9 mm T5 Torx screw securing the SSD to the logic board.

Image 1/2: Do not lift the end of the SSD excessively.
  • Use a spudger to help lift the free end of the SSD just enough to grab it with your other hand.

  • Do not lift the end of the SSD excessively.

  • Pull the drive straight out of its socket and remove it from the logic board.

  • When reinstalling the SSD, be sure it is properly seated before reinstalling its retaining screw.

When you've completed all these steps to replace your SSD, don't despair if the MacBook Air shows a flashing folder with a question mark when you first power up the MacBook Air.

- Power off the machine, then keep the option key (= Alt key) pressed down, power on the machine again, and keep the option key pressed down until a prompt appears.

- If you've set a firmware password, then type it in at the prompt

- You should now be prompted for a hard drive to boot from. Select "EFI Boot"

- The MacBook Air should now boot to a window showing "OS X Utilities"

- Click on the  at the top left, then select "Startup Disk..."

- Select your SDD/Hard drive, and restart.

Image 1/1: Two 5.2 mm T5 Torx screws
  • Remove the following three screws securing the fan to the upper case:

    • Two 5.2 mm T5 Torx screws

  • 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.

The replacement fan's ribbon cable is a few mm longer than the original. I t will loop upwards a bit after mounting. The rubber lip on top of the old fan needs to be transferred to the new fan.

  • 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.

  • Logic board remains.

  • 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.
