If your trackpad is broken or needs to be removed for easier access to the battery, follow these steps.

For your safety, discharge your MacBook Pro's battery below 25% 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. This command may not work on all Macs. Power on your Mac and launch Terminal. Copy and paste the following command (or type it exactly) into Terminal:

    • 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. Note: Your return key may also be labeled ⏎ or "enter."

    • 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

    Is this step necessary? I can’t perform this step as I am attempting to repair water damage and need to remove logic board & most likely replace the battery.

    @mac_medic You definitely don’t want the power coming on while the board is wet. In your case, I think powering on the machine to disable Auto Boot would do more damage than it prevents. I agree, skip this step and be prepared to disconnect the battery quickly if the laptop automatically powers on. Good luck!

    Jeff Suovanen -

    Thats right! You don't want power running while working on your logic board.

    This did not work when running High Sierra.

    Tried this on a 2018 MBP 13” Touchbar (there’s no iFixit guide for this model yet). Need to replace a broken screen.

    Luckily I managed to connect to an external screen (Cmd-Down Brightness to switch displays) and enter above command. Seems to work, but there’s another problem with this model - it powers up as soon as any key is pressed……. ffs <gnashes teeth>

    I unscrew the battery first and wrap electrical tape over the logic board battery connector before attempting any repairs to the board. Haven’t had any problems yet and I’ve worked on about 10 of these models already. Also when you open the bottom case use a suction cup at the bottom and pull up then run a plastic spudger along the edges to disconnect the clips. Also only use a plastic spudger on the board. Saw a youtube video from a repair shop and he did not disconnect the power and used all metal tools during the entire process of removing the board. His last step was to disconnect the battery terminal.

    BEFORE YOU START: The included torx head stripped off before I was done (and you might need an additional T4) so stop now and go buy a good one. Also they fail to warn you above to get some blue threadlocker ahead of time.

    This command did not work for me and I read that sometime in later 2020 Apple stopped this command from working…any ideas on a work around?

    Hi. This does not work on 2018 13” MacBook Pro with Touch Bar. I did exactly this to disable auto boot. But when I check by using nvram -p it says: auto-boot true. Am I doing something incorrectly? I did everything step by step. Copied and pasted the sudo command, pressed enter and then entered my password. I have Big Sur 11.1 installed. Is there any other way since I need to replace the screen. Thank you. Adrian

    Adrian Vizik - Ответить

    Hi everyone. This is also a little pointless if you can’t see anything on the screen, and you don’t have a display adapter to USB C to display it. I agree with Brian about removing the back and disconnecting the battery cable before you even think about opening the lid of the MacBook. Applying the insulation tape is also a handy little tip that just makes sure there is no way to discharge from either the board or battery.

    running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted

    result: `AutoBoot %00`

    Marek Polák - Ответить

    Running Big Sur 11.6.7 on a 2019 16" MBP, it's "auto-boot". So it's: nvram -p | grep 'auto-boot' to display the current state, the default is true - and then to change it, sudo nvram auto-boot=false which turns it off.

    Ed Mechem -

    This step is completely unnecessary if you follow the guide to disconnect the battery properly. Just put some tape between the battery and logic board connection to prevent it from accidentally touching and therefore powering on the laptop.

    It took me a few tries to make this command work, as I was able to copy and paste the command into Terminal, but could not type in my laptop’s password. I finally typed my password into a text document, copied it (command C), and then pasted it into Terminal and it worked.

    I didn’t do this. Mine never auto-booted before I replaced the battery. Now it does.

    BEFORE YOU DO ANYTHING - CHECK THE BATTERY!

    I-fixit sent me a bad battery, which I didn’t realize until it was already install. They sent me a new one, but I wasted hours uninstalling and reinstalled.

    Get a volt meter and measure the voltage on the output of the battery pack. If it reads 0 V, SEND IT BACK. It should read over 2 V.

    When I did this from Terminal.app within Recovery Mode, the “sudo” was not recognized but I could invoke it without the sudo part. It seems to have been accepted when looking at “nvram -p”

    johann beda - Ответить

    When in Recovery Mode, you already have superuser powers. So you don't need to prefix commands with the sudo command to invoke them with root privileges; you already have them. Do a pwd (print working directory) after opening Terminal in Recovery Mode, and you'll see that you're in the root user's directory.

    Ed Mechem -

    I received the battery kit for my 2018 MacBook Pro and as per the above comment from bcardanha - Oct 12, 2021, I checked the voltage on the pads marked + and - . It was zero volts so I panicked a bit.

    I sent a message on the iFixiT Facebook page and I got no reply. I finally found the customer service email for Ifixit Europe and sent them an email voicing my concern as I was not keen to work for couple of hours just to discover that the battery is faulty. I had an almost instant reply on the email (kudos to them) and they adviced me to go ahead and install the new battery as the voltage measured when battery is not connected is not relevant.

    I took a leap of faith and after two hours… the new battery showed 50% charge and everything seems to be working just fine. I am happy it worked.

    After removing the old battery and installing the new battery I powered up the MBP before screwing the bottom on. I discovered the my keyboard would not function. It took a few hours of investigation and frustration that I discovered the track pad power ribbon had become partially dislodged from the trackpad. I was able to see that this through the little machined slot where the battery sat. I had to remove the trackpad to reinsert the power ribbon back into the connector in the trackpad. after reassembling and reinstalling the battery etc the keyboard worked. Just food for thought if your run into the keyboard issue.

    This should be the default. IMO I tell you to power on - not the lid.

    • Before you proceed, 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

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

    Ciao Stefano! Grazie per il commento. Infatti c’è sempre una certa tolleranza fra il cacciavite e la testa delle viti. Quindi è possibile che un cacciavite più grande o più piccolo sia più “comodo” in certi casi. Buona riparazione!

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 installing.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
