Introduzione
Se il tuo trackpad è guasto o deve essere rimosso per accedere più facilmente alla batteria, segui questa guida.
Per la tua sicurezza, scarica la batteria del tuo MacBook Pro prima di iniziare. Se forata inavvertitamente, una batteria al litio-ioni può dar luogo a un incendio pericoloso e incontrollabile.
Cosa ti serve
-
-
Accendi il tuo Mac e apri Terminal.
-
Copia e incolla il seguente comando (oppure digitalo esattamente) in Terminal:
-
sudo nvram AutoBoot=%00
-
Premi [return]. Se richiesta, inserisci la tua password di amministratore e premi di nuovo [return]. Nota: il tuo tasto return può essere etichettato anche come ⏎ o "enter."
-
sudo nvram AutoBoot=%03
-
-
-
Usa un cacciavite pentalobe P5 per rimuovere le sei viti fissaggio della cover inferiore.
-
Due viti da 6,2 mm
-
Quattro viti da 3,4 mm
-
-
-
Applica una ventosa alla cover inferiore in centro vicino alla parte anteriore del MacBook Pro.
-
Tira la ventosa per creare una sottile fessura tra la cover inferiore e la scocca.
-
-
-
Inserisci l'angolo di un plettro di apertura nello spazio tra la cover inferiore della scocca.
-
Fai scorrere il plettro di apertura attorno all'angolo più vicino, fino a metà strada del lato del case.
-
-
-
Ripeti il passo precedente sul lato opposto, facendo scorrere il plettro di apertura sotto la cover inferiore e lungo il lato per poter sganciare la seconda clip.
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.
-
-
-
Inserisci il plettro di apertura di nuovo sotto il bordo anteriore del case inferiore, vicino a uno dei fori delle viti più centrali.
-
Applica una decisa torsione al plettro per liberare la terza clip di fissaggio.
-
Ripeti questa procedura vicino all'altro dei fori più centrali delle viti, liberando così la quarta clip.
-
-
-
Tira la cover inferiore con decisione verso la parte anteriore del MacBook (allontanandolo quindi dalla zona delle cerniere) per separare l'ultima clip di fissaggio del case.
-
Tira prima da un angolo e poi dall'altro
-
-
-
Rimuovi la cover inferiore.
-
Disponilo in posizione e allinea le clip scorrevoli vicino alla cerniera dello schermo. Premi la cover verso il basso e quindi falla scorrere verso la cerniera. Dovrebbe smettere di scorrere una volta che le clip si sono agganciate.
-
Quando le clip scorrevoli sono completamente agganciate e il case inferiore appare allineato correttamente, premi la cover con fermezza per agganciare le quattro clip sottostanti. Dovresti percepire e udire le clip che scattano in posizione di bloccaggio.
-
-
-
-
Stacca con cautela l'ampio pezzo di nastro adesivo che copre il connettore della batteria, sul bordo della scheda logica più vicino alla batteria stessa.
-
Rimuovi il nastro adesivo.
-
-
-
Usa la punta di spudger per sbloccare, sollevandola, la piccola aletta di bloccaggio nera che trattiene il cavo nel suo connettore.
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 :)
-
-
-
Scollega il cavo dati della scheda batteria facendolo scorrere fuori dal suo zoccolo.
-
Fai scorrere il cavo parallelamente alla scheda logica, nella direzione del cavo stesso.
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.
-
-
-
Piega da una parte, in modo che non interferisca, il cavo dati della scheda batteria.
-
-
-
Usa uno spudger per sollevare con delicatezza il connettore dell'alimentazione della batteria, scollegando quindi la batteria stessa.
-
Solleva il connettore quanto basta perché resti separato dal suo zoccolo. Se dovesse fare contatto accidentalmente nel corso della tua riparazione, il tuo MacBook Pro si potrebbe danneggiare.
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.

-
-
Usa un cacciavite Torx T3 per rimuovere le due viti da 1,8 mm che fissano la staffa del connettore del cavo del trackpad.
-
-
-
Usa uno spudger per disconnettere il cavo a nastro del trackpad facendo leva delicatamente per sollevare il suo connettore dalla scheda logica.
-
-
-
Prepara un iOpener e deponilo sopra il cavo a nastro del trackpad per circa un minuto, questo per ammorbidire l'adesivo che fissa il cavo a nastro del trackpad alla parte superiore della batteria.
-
Se non hai un iOpener, puoi usare un asciugacapelli per riscaldare il cavo. Il cavo deve essere caldo, ma non al punto da scottare se lo tocchi. Stai attento a non surriscaldare la batteria.
-
-
-
Stacca con cautela il cavo a nastro del trackpad dalla batteria e disponilo in modo che non dia fastidio.
-
-
-
Usa un cacciavite Torx T5 per rimuovere le dieci viti che fissano il gruppo del trackpad:
-
Due viti da 4,3 mm
-
Otto viti da 5,8 mm
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.

Rimuovi il gruppo del trackpad.
-
Stai attento a non perdere le sei piccole rondelle (due circolari e quattro rettangolari) disposte nella faccia inferiore del trackpad.
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 - Replica
@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>
Cool_Breeze - Replica
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(

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 - Replica
Not able to do that with damaged screen
richardjgreen - Replica
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 - Replica
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 - Replica
running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted
result: `AutoBoot %00`
Marek Polák - Replica
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 - Replica
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.
bcardanha - Replica
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 - Replica
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.
Ed Mease - Replica
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 - Replica
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.

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 - Replica
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 - Replica
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 - Replica
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.
