Introduction

Use this guide to replace the logic board in your Retina MacBook 2015. The logic board includes a flash storage chip containing all of your personal data, so make sure it's backed up (if possible) before attempting this repair.

To avoid logic board damage, when your MacBook repair is complete but before powering it on, connect it to low-voltage power using a 5-Watt iPhone charger and a USB-C to USB-A cable. These accessories are not included with your MacBook, so make sure you have them ready before you begin.

  • Before proceeding, unplug and power down your MacBook. Close the display and flip it upside-down.

    • 2015 models only: To avoid logic board damage, when your MacBook repair is complete but before powering it on, connect it to low-voltage power using a 5-Watt iPhone charger and a USB-C to USB-A cable.

  • Remove the following eight screws securing the lower case:

    • Two 1.8 mm P5 Pentalobe screws

    • Four 2.9 mm P5 Pentalobe screws

    • Two 6.1 mm P5 Pentalobe screws

  • Note the orientation of the screws as you remove them—they need to be reinstalled at a slight angle.

  • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

Wedge your fingers between the upper case and the lower case, starting from the rear of the MacBook between the hinges. Lift the lower case only slightly to avoid damaging the cables that connect the lower case to the upper case. Keeping a firm grip, lift steadily until the lower case separates slightly from the upper case.

    • Keeping a firm grip, lift steadily until the lower case separates slightly from the upper case.

    • You may experience a lot of resistance when lifting the lower case. If necessary, slide an opening pick or other ESD-safe pry tool down the side edges of the lower case to pop the two hidden retaining clips free.

    • During reassembly, to re-engage the clips, press firmly near both side edges of the lower case (near where the pick is inserted in the third image) until you hear the clips snap into place.

Lift the upper case and display together from the front edge and raise it to about a 45˚ angle. It may be helpful to prop the MacBook open in this position for the next step.

Use the flat end of a spudger to press and hold the small gold battery discharge button. If the power LED is lit up, continue holding the discharge button until the LED goes dark, and then release. This may take up to 10 seconds. If the LED does not light, release the button after 5-10 seconds. Press and hold it again for 5-10 seconds, and release. Finally, press and hold it a third time for 5-10 seconds, and release.

  • Take care not to damage the ribbon cables that still attach the lower case to the MacBook.

Before the IPD flex cable can be removed the battery disconnect button has be held down for up to 10 seconds. If the LED near the battery connector is switched on it shows that there is power going through the logic board from the battery, once the button is pressed and this light goes off the machine is safe to be worked on.

Carefully turn the MacBook over, so that the lower case lays flat. Raise the upper case/display assembly to about a 90° angle, and prop it up against something sturdy so you don't have to hold it.

    • Add a piece of tape near the track pad to secure the upper case and prevent accidental movement.

  • It's possible to open the MacBook all the way and lay both sides down flat, but this may damage the flex cables and is not recommended.

Remove the single 2.9 mm T5 Torx screw securing the battery connector to the logic board. 2015 models have a silver grounding clip with two foam pads directly under this screw, which may come loose. Be sure to reinstall it during reassembly.

the moment you opening macbook case and before any tinkering with connections, you MUST press little yellow button on logicboard, located on the right from battery connector - this will disable all power to the board. You can check by looking at the small led on left side of the battery connector - if there is very faint light, it means that power is still there. After pressing button light should go off. Removing screw is not necessary at all, and like I said - you MUST disable power before any touching to connections etc.

Use the flat end of a spudger to disconnect the USB-C port cable bracket by prying it straight up from the logic board. To reconnect this cable, first line up the metal bracket over the screw holes, then press down on the middle of the bracket. Make sure it's aligned correctly, or you may damage the connector.

  • Carefully slide the flat end of a spudger underneath the display cable to separate the adhesive holding it to the lower case.

    • Take care not to damage the cable. If it doesn't separate easily, heat the cable and/or the case directly beneath it with a hair dryer or iOpener to soften the adhesive, and try again.

    • The flap must remain closed when the cable is reinserted during reassembly. Carefully line up the cable with the gold contacts facing down, and gently slide it into the connector. Take care not to crimp or damage the cable. When fully inserted, the indentations on the sides should not be visible.

Use tweezers to disconnect the first antenna connector by lifting it straight up from its socket. The antenna connectors and sockets are extremely fragile. Be very careful to lift only on the connector, and not on the socket itself. Do not lift under the cable, or put any unnecessary strain on it.

If you are replacing the logic board once the machine has been rebuild the 2015 model has to have a 5W power adapter plugged into the machine first before the full 29W power supply otherwise there is a risk of damaging the logic board. Once the power is supplied the battery disconnect LED will switch on and once this has occurred you can remove the 5W and supply the machine with the full 29W power adapter.

Conclusion

To reassemble your device, follow these instructions in reverse order. To avoid logic board damage, when your MacBook repair is complete but before powering it on, connect it to low-voltage power using a 5-Watt iPhone charger and a USB-C to USB-A cable.
