Introduction

This serves as the starting point for every repair on your MacBook Pro. You'll need a P5 Pentalobe screwdriver to remove the lower case and get into the device.

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.

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. Power on your Mac and launch Terminal. Copy and paste the following command (or type it exactly) into Terminal:

  • 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

    • Two 5.3 mm screws

    • Two 3.4 mm screws

Before any repair is carried out that involves removing the bottom case, the machines auto-boot function has be disabled. This can be disabled via the terminal command “sudo nvram AutoBoot=%00” once the repair has been completed the auto-boot function can be re-enabled via the vermin command “sudo nvram AutoBoot=%03”.

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.

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.
