Introduction

This guide demonstrates how to disconnect the battery in your MacBook Pro 14" Late 2023 (M3).

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

    • Use a P5 pentalobe driver to remove the eight screws securing the lower case:

    • Four 9.2 mm-long screws along the back edge (near the screen hinge)

    • Four 5 mm-long screws along the front edge (near the trackpad)

    • Sliding clips along the back edge of the MacBook secure the lower case. In this step, you'll shift the lower case away from the hinges to free it from these clips.

    • Insert the flat end of a spudger between the lower case and the right screen hinge.

    • Lever your spudger against the hinge to push the lower case away from it.

    • Repeat for the left hinge.

    • After you've released the sliding clips along the back edge, four remaining clips secure the lower case to the frame:

    • Two clips near the cutouts in the frame

    • Two clips near the middle of the lower case

    • As you release the lower case from the frame, you'll hear and feel a distinct "pop" as each of these four clips release.

    • Don't insert your tool deeper than 1 cm (a little less than half an inch) near the front of the speaker cutouts to avoid damaging the speakers.

    • Insert the flat end of your spudger into the front of the cutout in the right side of the frame.

    • Slide your spudger toward the back of the cutout and pry up to release the two right-side clips.

    • Repeat for the left-side speaker cutout to release the two left-side clips.

    • Remove the lower case.

    • To reinstall the lower case:

    • Lay it down and align the sliding clips with the back edge of the MacBook. Press down on the lower case and slide it toward the back edge to engage the clips.

    • When one side is engaged, it may push the other out of alignment. Check both sides as you push.

    • Once the back corners of the lower case are secured and flush with the frame, press down along the middle of the lower case to engage the four remaining clips.

    • You'll hear and feel each clip snap into place.

    • Use the flat end of your spudger to pry up and disconnect the trackpad press connector from the logic board.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't force it, since a misaligned connector can bend the pins, and cause permanent damage.

    • Light adhesive secures the trackpad cable to the battery board.

    • Peel the trackpad cable from the battery board and move it over the front edge of the MacBook.

    • Be careful not to crease or damage the cable.

    • The battery data cable is adhered to the battery board and logic board. In the next few steps, you'll disconnect it, separate its adhesive, and remove it.

    • Heat an iOpener and place it on the battery data cable for 30 seconds to soften its adhesive.

    • If you don't have an iOpener, you can use a hair dryer to lightly heat the cable. Be careful not to overheat the battery, as doing so is a fire hazard.

    • Use the flat end of your spudger to lift the main battery connector away from the battery board, disconnecting the battery.

    • Lift the connector high enough that it doesn't accidentally make contact during the repair, but no more than 45 degrees to prevent breaking it.

    • For added safety, place a non-conductive barrier, such as a piece of a playing card, between the connector and board.

Conclusion

To reassemble your device, follow these instructions in reverse order.
