Einleitung
Wenn dein Trackpad defekt ist oder entfernt werden soll, um besser an den Akku zu gelangen, dann ist diese Anleitung die richtige für dich.
Um das Sicherheitsrisiko zu verringern, solltest du den Akku deines MacBook Pro vollständig entladen, bevor du mit der Reparatur beginnst. Ein geladener Lithium-Ionen-Akku kann ein gefährliches und unkontrollierbares Feuer verursachen, wenn er versehentlich beschädigt wird.
Was du brauchst
-
-
Schalte deinen Mac ein und starte Terminal.
-
Kopiere den folgenden Befehl und füge ihn im Terminal ein (oder tippe ihn exakt so ein):
-
sudo nvram AutoBoot=%00
-
Drücke die Eingabetaste [return]. Wenn du dazu aufgefordert wirst, gib dein Administratorpasswort ein und drücke erneut [return]. Hinweis: die Return-Taste kann auch mit ⏎ oder "enter" gekennzeichnet sein.
-
sudo nvram AutoBoot=%03
-
-
-
Entferne die sechs Schrauben, mit denen das Gehäuseunterteil befestigt ist, mit einem Pentalobe P5 Schraubendreher:
-
Zwei 6,2 mm Schrauben
-
Vier 3,4 mm Schrauben
-
-
-
Drücke einen Saugheber vorne mittig auf das Gehäuseunterteil des MacBook Pro.
-
Hebe den Saugheber an, damit zwischen dem Gehäuseunterteil und dem Rahmen ein kleiner Spalt entsteht.
-
-
-
Setze eine Ecke eines Plektrums in den Spalt zwischen dem Gehäuseunterteil und dem Rahmen ein.
-
Schiebe das Plektrum um die nächstgelegene Ecke und bis zur Hälfte an der Seite des Gehäuses entlang.
-
-
-
Wiederhole den vorigen Schritt auf der gegenüberliegenden Seite, indem du das Plektrum unter das Gehäuseunterteil steckst und entlang der Seite nach oben führst, bis die zweite Raste gelöst ist.
Recommend being very careful on this step and the following step when using any opening tool to always keep the “pointy end” up when prying, especially about 40mm up the side, to avoid completely destroying the speaker diaphragms.
-
-
-
Stecke das Plektrum jetzt nochmal unter den vorderen Rand des Gehäuseunterteils, bei einem der beiden mittleren Schraubenlöcher.
-
Drehe das Plektrum kräftig, damit die dritte Raste gelöst wird, mit der das Gehäuseunterteil am Rahmen befestigt ist.
-
Wiederhole diesen Vorgang bei dem anderen Schraubenloch in der Mitte und löse auch die vierte Raste.
-
-
-
Ziehe das Gehäuseunterteil fest zur Vorderseite des MacBooks hin (weg von den Scharnieren), so dass sich die letzten Rasten lösen, mit denen das Gehäuseunterteil noch befestigt ist.
-
Ziehe erst an der einen Ecke, dann an der anderen.
-
-
-
Entferne das Gehäuseunterteil.
-
Lege es richtig hin und richte die Klammern nahe am Scharnier aus. Drücke es nach unten und schiebe die Abdeckung zu den Scharnieren hin. Es sollte sich nicht mehr weiter schieben lassen, wenn die Klammern einrasten.
-
Wenn die Klammern ganz eingerastet sind und das Gehäuseunterteil korrekt ausgerichtet ist, dann drücke fest auf das Gehäuseunterteil, um die vier versteckten Klammern darunter einrasten zu lassen. Du solltest das Einschnappen spüren und hören können.
-
-
-
-
Ziehe vorsichtig das große Stück Klebeband ab, das den Akkustecker am Rand des Logic Boards ganz nah am Akku abdeckt.
-
Entferne das Klebeband.
-
-
-
Ziehe vorsichtig das kleine Stück Klebeband ab, mit dem der Stecker des Datenkabels an der Akkuplatine abgedeckt ist.
-
-
-
Mit der Spitze eines Spudgers kannst du jetzt die kleine schwarze Verriegelung umklappen, mit der das Kabel gesichert ist.
Be very careful here. It is easy to break the whole connector off the battery board, which is what I did. Luckily the connector is part of the replacement battery, so you just need to remove the connector from the cable. The pictures here should provide more detail so you can see better what is going on.
thanks a lot !!!!! great help :)
-
-
-
Schiebe das Datenkabel der Akkuplatine, aus seinem Anschluss heraus und trenne es ab.
-
Schiebe es parallel zum Logic Board in Richtung des Kabels.
As simple as this step might seem, the golden leads will disapper the moment you remove it as it has some adhesive under the black strip that covers it. Ensure you peel it back enough to display the golden leads after swapping the batteries out.
Your battery may come with this ribbon cable. In that case, disconnect the other end.
-
-
-
Biege das Datenkabel der Akkuplatine zur Seite, so dass es nicht mehr im Weg ist.
-
-
-
Nimm einen T5 Torx-Schraubendreher und entferne die 3,7 mm Flachkopfschraube vom Stecker der Stromversorgung am Akku.
-
-
-
Hebe jetzt den Stecker am Akkuanschluss mit einem Spudger vorsichtig an und trenne dadurch den Akku ab.
-
Hebe den Stecker so hoch an, dass er auch wirklich vom Anschluss getrennt bleibt. Wenn es im Laufe der Reparatur versehentlich zu einem Kontakt kommt, könnte dein MacBook Pro dadurch beschädigt werden.
To completely avoid accidental contacts I recommend to wrap this connector in a piece of paper and hold it in place with tape.
Do not put tape directly on the contact underside, as that may leave some glue that would affect the contact conductivity.
I put a piece of tape on the underside of the connector (sticky side up) to insure against accidental battery contact. If you put tape on the logic board side of the connection, some insulating padding material might accidentally stick to the tape when the tape is removed during reassembly.
-
-
-
Entferne die beiden 1,8 mm Torx T3 Schrauben, mit denen die Halterung am Stecker des Trackpadkabels befestigt ist.
-
-
-
Hebe mit dem Spudger den Stecker am Trackpad-Flachbandkabel vorsichtig gerade vom Logic Board hoch und trenne das Flachbandkabel ab.
-
-
-
Erwärme einen iOpener und lege ihn etwa eine Minute lang auf das Trackpad-Flachbandkabel. Dadurch wird der Kleber aufgeweicht, mit dem das Flachbandkabel oben am Akku befestigt ist.
-
Wenn du keinen iOpener hast, kannst du das Kabel auch mit einem Haartrockner erwärmen. Das Kabel sollte warm sein, aber nicht so heiß, dass du es nicht mehr anfassen kannst. Überhitze den Akku auf keinen Fall.
-
-
-
Ziehe das Trackpad-Flachbandkabel behutsam vom Akku hoch und schiebe es aus dem Weg.
-
-
-
Entferne die zehn Torx T5 Schrauben, mit denen die Trackpadeinheit befestigt ist:
-
Zwei 4,3 mm Schrauben
-
Acht 5,8 mm Schrauben
Heating the wrist-pad area and carefully using a plastic card to separate the adhesive allowed me to remove the battery without needing to use the solvent or removing the track-pad. No need for taping the speakers.
I attempted as well the shortcut with no solvent and no track-pad removal. Also, I didn't apply heating. Everything was totally fine yet a bit risky. In such conditions it is very hard not using the spudger flat tip to lift the battery packs. Well, I highly recommend NOT using the spudger on the two central packs. In fact, it would be extremely easy to destroy surface mounted components on the track-pad board which would be accessible through the metal frame holes under the packs (see pics along this guide). Plastic cards are always fine. Next time, I would probably avoid spudger and introduce floss as shown in Picture 34 below.

-
Klappe das Display ein wenig auf, um an das Trackpad zu gelangen.
-
Führe das Trackpad-Flachbandkabel sorgfältig durch die Öffnung im Rahmen des MacBook Pro.
-
-
-
Entferne die Trackpadeinheit.
-
Verliere die sechs kleinen Unterlegscheiben (zwei runde und vier eckige), die sich auf der Unterseite des Trackpads befinden, nicht.
Should include instruction to wedge thin paper one every side of the trackpad to keep it aligned during reinstallation. Without the wedges, the trackpad would come out misaligned, which might damage it from excessive friction. Kapton tape might also work, didn't try it though.
These instructions were standard for Unibody models in the past, don't know why it wasn't included here.

How is the trackpad cable removed? is it simply adhesive or solder?
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.
Macrepair SF - Antwort
@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.
Dan -
This did not work when running High Sierra.
Kyle B - Antwort
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>
Cool_Breeze - Antwort
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.

Is this step necessary if my mac can turn on? Battery fully dead(
Nursat b - Antwort
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?
Patrick Machacek - Antwort
Not able to do that with damaged screen
richardjgreen - Antwort
If you have a damaged screen you can still use a converter from thunderbolt (USB 3) to HDMI and plug your Macbook Pro to your TV as monitor display. Just make sure to chose the right Source (HDMI IN) in your TV. I did it and to make it work I unplug and plug again in my Macbook and so I could disable the Auto boot

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 - Antwort
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.
Roberto Enrieu - Antwort
running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted
result: `AutoBoot %00`
Marek Polák - Antwort
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 istrue- and then to change it,sudo nvram auto-boot=falsewhich 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.
Grant Ormsby - Antwort
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.
tommy404 - Antwort
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.
bcardanha - Antwort
I've just received my replacement battery and it reads 0,042V between the two main connectors. Do you think it's dead?

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 - Antwort
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.
Mircea Comanici - Antwort
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.
Ed Mease - Antwort
This should be the default. IMO I tell you to power on - not the lid.

Est ce que cela fonctionne sur un macbook pro 2017 sans touchbar ?

Bonjour Maël, oui, ce tutoriel concerne "les MacBook Pro 2016 (et plus récents) et les MacBook Retina 12" 2017 (et plus récents)"
Claire Miesch -
Excellent instructions. I was able to follow and install the new screen. I recommend that you get a good set of tools before you begin. I started with an inexpensive repair kit bought online. The Penta and torx bits failed. I bought an IFIXIT kit with quality bits and I was able to do everything I needed.
Tom Markham - Antwort
If you're not running an admin account the sudo command won't work (which honestly, you should not be running admin). Rather than logging in to your admin amount via the OS, in the terminal type "login [admin username]," then the password and you'll be able to do the sudo command as described above. Once you're complete, type "logout [admin username]" and you'll be good to go. Obviously replace [admin username] with whatever the account name for your admin user is.
arichard2401 - Antwort
For those unable to complete this step because the screen is too damaged I recommend leaving your macbook on until the battery dies.
Nicholas R Licato - Antwort
Just replaced my 2018 15" MBP battery. Running Sonoma.
I found no way to disable AutoBoot (The status can be checked in the Power section of system report).
Anyway, i left my battery completely drain before opening the MBP, and had no issues during the process.
Cédric Bontems - Antwort
After sending this command in terminal when I checked what happens if I now open the lid, instead the screen lit slightly up (still black) then a battery symbol showing the charging state showed up.
Now, after replacement of the battery, this is all I get to see.
No reset of NVRAM nor PRAM helped.
Currently the new battery charges (58% atm) and it feels like it‘s mocking me.
webrockers - Antwort
I suspected the keyboard or TouchID sensor wouldn’t work, so I went on and checked every connector.
I missed connecting the left TouchID sensor from step 31.
