Sostituzione connettore batteria MacBook Pro 13" Touch fine 2016

Passo 1

Prima di iniziare, devi disabilitare l'Auto Boot del tuo Mac. Auto Boot accende il tuo Mac non appena apri il coperchio e può essere attivato accidentalmente in fase di smontaggio. Usa questa guida oppure segui le istruzioni abbreviate qui sotto per disabilitare l'Auto Boot. Questo comando potrebbe non funzionare su tutti i Mac.
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."
Ora puoi spegnere in sicurezza il tuo Mac e aprire la copertura inferiore senza accenderlo per sbaglio.
Quando la riparazione è terminata e il tuo Mac è stato riassemblato con successo, abilita nuovamente l'Auto Boot con il comando seguente:
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.

Macrepair SF - 02/07/19

@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 - 03/07/19

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 - 22/10/19

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 - 19/11/19

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.

Brian - 07/02/20

Is this step necessary if my mac can turn on? Battery fully dead(

Nursat b - 26/08/20

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.

Jason Sherron - 09/10/20

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 - 27/11/20

Not able to do that with damaged screen

richardjgreen - 15/12/20

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

Roberto Sanchez Bustos -

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 - 16/01/21

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 - 22/01/21

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

result: `AutoBoot %00`

Marek Polák - 01/02/21

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 - 24/06/22

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 - 11/03/21

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 - 28/04/21

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

hatuxka -

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 -

I've just received my replacement battery and it reads 0,042V between the two main connectors. Do you think it's dead?

peter sussex -

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 -

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 - 24/06/22

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 -

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 -

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

G Sena -

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

maël muzelet -

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 -

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 -

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 -

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 -

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 -

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.

Passo 2

Prima di iniziare, scollega l'alimentazione e spegni il tuo MacBook. Chiudi il display e poni il laptop rovesciato su una superficie morbida.
Usa un cacciavite pentalobe P5 per rimuovere le sei viti di fissaggio del case inferiore:
Due viti da 6,2 mm
Quattro viti da 3,4 mm
Nel corso di tutta la procedura, tieni traccia di ogni vite e assicurati che venga rimessa esattamente nello stesso posto da cui è stata estratta per evitare danni al tuo dispositivo.

Sur le mien A1708 EMC3164 j’ai 4 vis de 6,2 (les coins) et 2 vis de 3,4 celles au milieu en bas

Olivier Cecillon - 18/12/20

Ce tutoriel n’est pas dans la bonne section !

c’est le 13” avec touch bar et non celui avec les touches de fonction .

l’autre tuto nommé “écran complet” est le bon

Vincent Morault -

Bonjour Vincent,

Si vous cherchez le même tutoriel pour le MacBook 13” non Touch Bar, le voici : https://fr.ifixit.com/Tutoriel/Remplacem...

Claire Miesch -

Before you start I suggest you get magnifier eyeware as screws and connectors are very small and good lightning are a big PLUS

Gilles Vigeral -

Completed whole steps in over 4 hours….but worth it. Works back perfect and battery error message is gone….

Gilles Vigeral -

Nothing beats a properly grounded ESD workstation, and a grounded wrist strap.

Robin Ray -

Passo 3

Applica una ventosa al case inferiore vicino all'area centrale-anteriore del MacBook Pro.
Tira la ventosa quanto basta per creare una lieve fessura tra il case inferiore e lo chassis.

Passo 4

Inserisci un angolo del plettro di apertura nello spazio tra la cover inferiore e lo chassis.
Fai scorrere il plettro di apertura attorno all'angolo più vicino e fino a metà circa del lato del case.
In questo modo si sgancia la prima delle clip nascoste che fissano il case inferiore allo chassis. Dovresti sentire la clip che si apre.

The instruction implies that sliding the pick up to the side of the case releases the clip. This is far from the truth; it takes a pretty strong force to pop the clip open. The plastic pick is a good start, but you need to reach in and pull the middle of that side of the case pretty hard.

dkraemer2 - 19/01/19

Passo 5

Ripeti il passo precedente dal lato opposto, facendo scorrere il tuo plettro di apertura sotto la cover inferiore e salendo lungo il lato per liberare la seconda clip.

Passo 6

Inserisci il tuo plettro di apertura ancora una volta sotto il bordo anteriore del case inferiore, vicino a uno degli alloggiamenti delle viti più vicine al centro.
Ruota con una certa forza il plettro per liberare la terza clip che fissa la cover inferiore allo chassis.
Ripeti questa procedura vicino all'altro alloggiamento delle viti più vicine al centro per sganciare la quarta clip.

Look at Step 8 pics 2 and 3 to see exactly where the clips are that need to be released. Taking the bottom cover off my MBP took for ever because I didn’t realize the clips were not right around the edges as the wording suggests. Once I realized this, it came off quickly and easily.

Troy Reimche -

Passo 7

Tira il case inferiore con decisione verso la parte anteriore del MacBook (per allontanarlo dalla zona delle cerniere) per separare le ultime clip che fissano il case stesso.
Tira prima da un angolo e poi dall'altro.
Tira lateralmente e non verso l'alto.
Questa operazione può richiedere parecchia forza.

On the 2018 model, there are two more clips that need to be popped on the sides in the middle. Then it slides out easily.

Cool_Breeze - 19/11/19

Passo 8

Rimuovi il case inferiore.
Per installare di nuovo il case inferiore:
Metti in posizione e allinea le clip scorrevoli vicino alla cerniera del display. Premi verso il basso e fai scorrere verso la cerniera la cover; lo scorrimento dovrebbe interrompersi quando le clip si sono agganciate.
Quando le clip scorrevoli sono perfettamente agganciate e il case inferiore appare ben allineato, premi con decisione sul case inferiore per agganciare le quattro clip nascoste sottostanti. Dovresti percepire al tatto e sentire lo scatto di queste clip.

Passo 9

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.

Please be VERY careful, I torn up my battery cable and had to replace all the battery.

Emmanuel Neff - 17/11/20

Apple worked on my computer and did not put the tape back. I'm assuming it's not important?

ronfrank -

Passo 10

Stacca delicatamente il piccolo pezzo di nastro adesivo che copre il connettore del cavo dati della scheda batteria.
Questo nastro adesivo è integrato nel cavo a nastro e non si staccherà del tutto. Sollevalo, tirandolo indietro, giusto quanto basta per poter accedere al connettore.

While the tape in this step was definitely attached to the ribbon cable, I accidentally pulled it off during Step 9, thinking that it was a tab to remove the larger tape covering the whole battery connector. It didn’t seem to do any harm.

cdowney - 07/05/19

Passo 11

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. I had to repeat this procedure several times on my MacBook Pro to replace faulty monitors. Eventually, after being opened and closed so many times, the small black locking tab came right off of the connector. Now my battery connection is broken and I can only use my MacBook when it is plugged into the power supply. I’m trying to find a way to securely connect the battery cable without this little locking tab (maybe with tape or something), but so far no luck. Does anyone at iFixit have any advice for me?

Jamie Near - 18/07/20

Like Jamie said, use mass amounts of caution here. The lever is very fragile, and mine came off as well - and I’m not exactly a muscular guy. Without it, the connection cannot be made to the data connector, and the computer will not think that a battery is installed. I had to finagle my connector with tweezers and a spudger back into place (and the picture above makes it look normal sized. The picture lies. It is TINY! We’re talking smaller than a small eyelash tiny), and then used some of the adhesive battery strip to hopefully keep it in place.

Wayne Linder - 11/01/21

The previous comments are not exaggerated. There ain’t NOTHIN’ to that locking bar. I found it helpful to zoom in with my phone to work on it. It really requires no force to move, I imagine the tape is there to hold it down.

William Brittain - 06/02/21

See this conversation for @stevebsiegel’s solution.

l4ur3lz - 21/03/22

Passo 12

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.

Passo 13

Piega da una parte, in modo che non interferisca, il cavo dati della scheda batteria.

The cable is held down with adhesive. Be very gentle with the delicate cable as you peel it back.

dkraemer2 - 19/01/19

Passo 14

Usa un cacciavite Torx T5 per rimuovere la vite a testa larga da 3,7 mm che tiene bloccato il connettore dell'alimentazione della batteria.

Why is my screwdriver not turning even when I have the correct screwdriver and the screw is not stripped

Jia Liu -

Passo 15

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.

Dies ist kein Stecker sondern eine Kontaktplatte, die nur leicht angehoben werden muss. Dann am besten mit etwas Tesafilm isolieren.

SchroedersKater - 14/10/20

(Translation for myself and others; Thanks for the nice tip by the way!) This is not a plug but a contact plate that only needs to be lifted slightly. Then it is best to isolate with some scotch tape.
