Introdução

Use this guide to replace your Retina MacBook 2017's lower case assembly together with the battery as a single unit.

The battery is strongly glued into place and removing it from the lower case is beyond the scope of this guide, but it may be removed with a liquid solvent and gentle prying.

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

  • 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.

IMPORTANT. You’re not removing the bottom, yet. This step is solely to separate the panel from its clips, permitting inside access.

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.

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.

    • 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.

From my experience it’s important to carefully press and hold the small button above left of the Battery Discharge label. Use a plastic spudger or finger tip. The illuminated yellow LED to the right will go off. I believe this discharges remaining electricity from logic board protecting it during repair.

* I cannot find any documentation to support this, but I have damaged boards by not including this step.

You may keep pressing the button for Battery Disconnect while opening or loosening the battery screw, so it’s easier when inserting the battery isolation pick.

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.

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.
