Introdução

If your trackpad is faulty or needs to be removed for easier access to the battery, follow this guide.

For your safety, discharge your MacBook Pro's battery before you begin this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured.

  1. Before starting this procedure, you must disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide or follow the abbreviated instructions below to disable Auto Boot.

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

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

      • Two 6.2 mm screws

      • Four 3.4 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.

    • Apply a suction handle to the lower case near the front-center area of the MacBook Pro.

    • Lift the suction handle to create a slight separation between the lower case and the chassis.

    • Insert one corner of an opening pick into the space between the lower case and the chassis.

    • Slide the opening pick around the nearest corner and halfway up the side of the case.

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

    • Repeat the previous step on the opposite side, sliding your opening pick under the lower case and up the side to pop the second clip free.

    • Insert your opening pick once again under the front edge of the lower case, near one of the two centermost screw holes.

    • Give the pick a firm twist to pop free the third clip securing the lower case to the chassis.

    • Repeat this procedure near the other of the two centermost screw holes, popping the fourth clip free.

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

      • It may help to pull first at one corner, then the other. In case you aren't able to separate the clip from the lower case you can apply a suction cup next to the corner with the clip and carefully use it as a pulling handle.
