Retina MacBook 2017 Trackpadeinheit austauschen

Schritt 1

Zuallererst musst du die automatische Startfunktion (Auto Boot) deines Macs deaktivieren. Auto Boot schaltet deinen Mac ein, wenn du ihn aufklappst, was versehentlich beim Auseinanderbau passieren kann. Benutze diese Anleitung oder befolge die anschließende Kurzversion zum Deaktivieren von Auto Boot. Dieser Befehl funktioniert eventuell nicht auf allen Macs.
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.
Nun kannst du deinen Mac sicher herunterfahren und das untere Gehäuse öffnen, ohne dass er sich versehentlich einschaltet.
Nachdem deine Reparatur zu Ende ist und dein Gerät wieder erfolgreich zusammengebaut ist, musst du Auto Boot mit folgendem Befehl wieder aktivieren:
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 -

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.

Schritt 2

Bevor du weiterarbeitest, ziehe das Netzkabel und schalte das MacBook aus. Klappe das Display zu und lege den Laptop mit der Unterseite nach oben auf eine saubere weiche Arbeitsfläche.
Entferne folgende acht Schrauben, mit denen das untere Gehäuse befestigt ist:
Zwei 1,8 mm Pentalobe P5 Schrauben
Vier 2,9 mm Pentalobe P5 Schrauben
Zwei 6,1 mm Pentalobe P5 Schrauben
Schaue dir beim Ausbau die Lage der Schrauben genau an - sie müssen beim Eindrehen leicht schräg stehen.
Halte bei der ganzen Reparatur die Schrauben gut geordnet und passe auf, dass jede Schraube genau auf ihren alten Platz zurück kommt, damit keine Schäden am Gerät entstehen.

IMPORTANT. You’re not removing the bottom, yet. This step is solely to separate the panel from its clips, permitting inside access.

Chris Leeds - 30/04/18

The screws go in tangent to the curve of the case. If you aren’t used to handling small hardware try turning the screw counterclockwise while you feel for the hole until you feel it drop, that means the threads have aligned. It takes only light finger torque when they are threaded correctly

abscate - 27/02/20

Schritt 3

Zwänge deine Finger in den Spalt zwischen dem oberen und dem unteren Gehäuse. Beginne an der Rückseite des MacBooks zwischen den Scharnieren.
Hebe das untere Gehäuse nur ein wenig an, damit Schäden an den Kabeln, die das obere und untere Gehäuse verbinden, vermieden werden.
Fasse das untere Gehäuse fest an und hebe es gleichmäßig hoch, bis es sich vom oberen Gehäuse löst.
Möglicherweise geht das Hochheben des unteren Gehäuses schwer. Schiebe ein Plektrum oder ein anderes ESD sicheres Werkzeug an den Seitenkanten des unteren Gehäuses entlang , um die beiden versteckten Klammern zu öffnen.
Damit diese Klammern beim Zusammenbau wieder einrasten, musst du fest auf die beiden Seitenkanten des unteren Gehäuses drücken (in der Nähe des Plektrums im dritten Bild), bis du es einrasten hörst.

Schritt 4

Halte das untere Gehäuse gut fest und drehe das MacBook vorsichtig um, sodass das Apple Logo nach oben zeigt.

Schritt 5

Hebe das obere Gehäuse und das Display zusammen von der Vorderkante her nach oben an, bis es mit einem Winkel von etwa 45° steht.
Es ist hilfreich, wenn du es in dieser Stellung für den nächsten Schritt abstützt.

This displays two black pics to prop up the MacBook, but the kit only includes one black pic.

Kyle Swafford -

Schritt 6

Drücke mit dem flachen Ende des Spudgers die goldfarbene "battery disconnect" Taste und halte sie fest.
Wenn die Einschalt-LED aufleuchtet, dann halte die Taste weiterhin gedrückt, bis die LED erlöscht. Das kann bis zu 10 Sekunden lang dauern.
Wenn die LED nicht aufleuchtet, dann lasse die Taste nach 5-10 Sekunden los. Drücke und halte sie für weitere 5-10 Sekunden und lasse los. Drücke und halte sie zum Abschluss erneut für 5-10 Sekunden und lasse los.
Durch dieses Verfahren wird sichergestellt, dass das MacBook ganz heruntergefahren ist und sicher daran gearbeitet werden kann.

cannot turn on the led after replacing the new screen, even after following the turn on instructions upper…

Laurent Pierre - 07/10/18

on reassembly, I had to plug my laptop in to reactivate the LED light

aaron_vandyke2003 - 09/04/19

Does anyone know how to turn it back on..? I plugged the laptop in and saw the LED Light, but it won’t turn on

mmcsorley - 17/04/19

After reassembly I could not restart my MacBook using the power button or after SMC reset (shift-ctrl-option-pwr). I had to connect my MacBook to its charging cable to get the battery LED to re-illuminate. After that it was all normal.

Richard Lovatt - 18/09/19

It took a few minutes on the power adapter for my computer to turn on after it was reassembled.

Luk Chl - 09/02/20

mine doesnt turn on w anything, i forgot to click the buton to disconnect :_/

cristian.campuzano - 16/06/20

Same issue as above peeps. Followed ifixit directions verbatim and wasn't getting anything after screwing everything back in. Plugged in original 45W power block and waited, after few minutes battery LED came on and a min. or two after that, was able to get screen to turn on. Hope this helps somebody else.

Brandon Elliott - 21/07/20

May I ask how to get screen to turn on. I cannot get it work..

Xiubo Zhang - 19/12/20

For those whose Mac won't turn on.

See step 16

To reconnect this cable, first line up the metal bracket over the screw holes, then "PRESS DOWN" on the middle of the bracket.

There is a connector under the bracket, which you can't see if you don't see under.

Not having it in mind, you will not PRESS DOWN the middle of the bracket and there is no connect.

hls2005 -

There needs to be mention of procedure for getting the repaired MacBook to power up again after the repair is completed.

I also am running into the issue described by others. MB will not come on again, even after being plugged into power and performing an SMC reset.

Kinda stuck….

Carlos Perez - 05/04/21

Hi, I tried everything and my MacBook will not start up after replacing the bottom case with a battery installed. I decided to put back on the old case with the battery that needs servicing and it still will not power on. I am fairly experienced taking apart laptops I was an Apple service tech for 15 years. this has me baffalled. Any hints BTY the logic board does not show any power coming from the AC charger the power LED is not lit up

eestern -

I had trouble with this as well. What worked for me is to plug in power using the stock 29W USB C power brick that originally came with this Macbook. Trying other, lower powered, power adapters did not work. Use this advice with caution as there are multiple (i.e substantiated) comments that indicate that first power up should only be with a 5W adapter! So perhaps try this strict sequence: try with a 5W adapter, then and only then try with the 29W adapter. Or even slightly better, if everything else has completely failed, only then try full power 29W adapter.

LexxOne -

How long did you wait to get it power back on? I replaced my logic board and tried to connect the power charger but it doesnt still turn on.

Herb -

The easiest error to make when working on this motherboard if applying full voltage after re-assembly. According to the big A, the motherboard on these Macbooks need to be “woken up” with a 5 watt (phone size) charger. Applying the normal 29 watts may render your system unusable.

Noah - Feb 18, 2021

Hello Noah,

It seems your remark is only valid for the 2015 and not the 2016 edition.

David - Mar 3, 2021

While it’s true that the internal documentation specifies this for a 2015, after frying 2 motherboards with a normal charger, I spoke with the engineers and they told me that this also applies to 2016 and 2017 macbook main logic boards. I say- It can’t hurt to try to wake them up with a 5 watt charger first! Please take 5 minutes to save your motherboard.

Noah - Mar 4, 2021

Noah -

I plugged in my charger and the LED came on. The computer gets warm but the screen is not turning on. The keyboards doesn’t seem to respond to recovery options. Any suggestions?

J'Trel Sapp -

Hello in muy case the power LED does not go dark (off) . Holding more than 10 sec and nothing. Somebody?

Flavio - 17/03/23

The led light doesn’t turn off on mine either. Held for 10 sec 3 times and still on. How do I turn it off now? And will it damage the computer if I work on it with the light on?

sfalba -

Also, which way should the track pad flex cable face when reinstalling it?

sfalba -

Schritt 7

Schließe das MacBook und lege es mit der Unterseite nach oben hin.

Schritt 8

Hebe die Vorderkante hoch, bis das untere Gehäuse mit einem Winkel von etwa 45° geöffnet ist.
Achte darauf, dass die Flachbandkabel, mit denen das untere Gehäuse immer noch am MacBook angeschlossen ist, nicht beschädigt werden.

Schritt 9

Löse mit einer Pinzette das Klebeband ab, mit dem der ZIF Verbinder des Trackpadkabels bedeckt ist.

Where can I find a replacement cable?

John Comix - 10/03/20

Just worked on one that was missing the tape from the factory, so yours may not have it either.

maccentric -

that cable got damaged, and now my macbook won't turn on anymore. Does this cable prevent the macbook from working?

ITZ CRONOMO -

Schritt 10

Klappe vorsichtig den Sicherungsbügel am ZIF Verbinder des Trackpadkabels mit einem Spudger hoch.

The small retainer flips up about 90 degrees from locked position

abscate - 27/02/20

The keyboard and trackpad don't work after the repair, what can I do? They don't even show up in System Report.

bredelet -

I found that the connector was not pushed enough in. Works now.

bredelet -

Schritt 11

Ziehe das Flachbandkabel des Trackpads vorsichtig durch den Schlitz im Rahmen vom Trackpad ab.

Schritt 12

Schließe das MacBook sorgfältig und drehe es wieder um, so dass das Apple Logo nach oben zeigt.
Klappe das obere Gehäuse/Display Einheit etwa rechtwinklig auf und stütze es an einem stabilen Gegenstand, so dass du es nicht festhalten brauchst.
Klebe das obere Gehäuse mit einem Klebeband in der Nähe des Trackpads fest, so dass es sich nicht versehentlich bewegen kann.
Man könnte zwar das MacBook die ganze Zeit flach aufgeklappt lassen, dies ist aber nicht zu empfehlen, da die Flachbandkabel beschädigt werden können.

Schritt 13

Entferne die einzelne 2,9 mm Torx T5 Schraube, mit der der Akkuanschluss am Logic Board befestigt ist.

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.

Chris Leeds - 30/04/18

I don't know what guide your on, but step 6 of the guide to replacing the USB-C cable has you press this button (3 times even).

maccentric -

What is with the all plastic end of this cable that appears to just be glued right on top of its connector?

Does the new one just stick back right on top?

(In this photo it is the bottom side of the cable below the white water indicator sticker)

Elizabeth Erkelens - 18/04/19

Schritt 14

Als zusätzliche Sicherheitsmaßnahme kannst du den Akku physisch trennen, indem du ein Akkuisolierstück zwischen Logic Board und Akkuanschluss einsetzt.

What happen if you don’t disconnect the battery? I didn’t and I saw smoke coming out when I connected the pad flex cable and the computer still started up

DSANTIAGOSOY - 31/03/19

If you don’t disconnect the battery you might accidentally short something on the logic board since power is still running through everything while you’re working on it. You can complete the repair without disconnecting the battery, but you risk accidentally breaking your logic board. It’s much safer to keep the battery disconnected while you’re working.

Adam O'Camb - 03/04/19

Schritt 15

Entferne mit einer Pinzette das Klebeband vom Stecker des Flachbandkabels zur Tastatur auf dem Trackpad.

Schritt 16

Klappe mit dem Spudger den Sicherungsbügel am ZIF Verbinder des Flachbandkabels zur Tastatur hoch.

Schritt 17

Ziehe vorsichtig das Flachbandkabel zur Tastatur aus seinem Schlitz im Rahmen heraus.

Schritt 18

Entferne die fünf 2,5 mm Torx T3 Schrauben, mit denen das Trackpad am Gehäuse befestigt ist.

This may require a T4 for the MacBook Retina early 2015. A T3 was too small, but this machine already had a replacement keyboard and body due to Apple recall. Just be aware.

Neal Abrams - 29/01/19

I should read this comment. I think my Mac Book have T4 screws. Thanks a lot.

GOCHI MOTOHIRO - 12/10/20

2015 here also had t4

Greg Lavardera -

Schritt 19

Klappe das Display ein wenig auf, so dass die Trackpad Einheit vom oberen Gehäuse frei kommt und entferne die Trackpad Einheit.
Es kann beim Ausbau vorkommen, dass auf beiden Seiten des Trackpads metallene Halteklammern herausfallen. Achte darauf, dass du sie beim Zusammenbau so wie auf dem Bild gezeigt wieder einbaust.
