    • Completely power off and unplug your MacBook Pro before you start. Close the display and flip the entire laptop upside-down.

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

    • Four 9.1 mm screws

    • Four 5 mm screws

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

    • Insert an opening pick into the gap you just created.

    • Slide the opening pick around the nearest corner and then halfway up the side of the MacBook Pro.

    • This releases the first of the hidden clips securing the lower case. You should feel and hear the clip pop free.

    • Repeat the previous step on the other side, using an opening pick to to release the second clip.

    Terrifying, don't be afraid, give it a good pull, the description above is exactly right.

    • Pull firmly to slide the lower case towards the front edge of the MacBook (away from the hinge area) to separate the last of the clips securing the lower case.

    • Pull first at one corner, then the other.

    • Pull to the side—not up.

    • This may require a lot of force.

    • Remove the lower case.

    • To reinstall the lower case:

    • Set it in place and align the sliding clips near the display hinge. Press down and slide the cover toward the hinge. It should stop sliding as the clips engage.

    • When the sliding clips are fully engaged and the lower case looks correctly aligned, press down firmly on the lower case to engage the four hidden clips underneath. You should feel and hear them snap into place.

Conclusion

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

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.
