  • Power on your Mac and launch Terminal.

  • Copy and paste the following command (or type it exactly) into Terminal:

    • sudo nvram AutoBoot=%00

  • Press [return]. If prompted, enter your administrator password and press [return] again.

  • You can now safely power down your Mac and open the bottom case, without it accidentally powering on.

  • When your repair is complete and your Mac is successfully reassembled, re-enable Auto Boot with the following command:

    • sudo nvram AutoBoot=%03

  • Before proceeding, unplug and 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.

    • During reassembly, to re-engage the clips, press firmly near both side edges of the lower case (near where the pick is inserted in the third image) until you hear the clips snap into place.

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.

Finally, press and hold it a third time for 5-10 seconds, and release.

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.
