Introducción

Quitar la cubierta inferior es el punto de partida para todas las reparaciones.

Por tu seguridad, vacía la batería de tu MacBook Pro por debajo del 25% antes de comenzar este procedimiento.

Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201, Desactivar el arranque automático: paso 1, imagen 1 de 3 Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201, Desactivar el arranque automático: paso 1, imagen 2 de 3 Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201, Desactivar el arranque automático: paso 1, imagen 3 de 3
    • Antes de comenzar, debes desactivar la función de arranque automático de tu Mac. Auto Boot se enciende en tu Mac cuando abres la tapa y puede activarse accidentalmente durante el desmontaje. Usa esta guía o sigue las instrucciones abreviadas a continuación para deshabilitar el inicio automático. Este comando podría no funcionar en todas las Macs

    • Enciende tu Mac y ejecuta Terminal.

    • Copia y pega el siguiente comando (o escríbelo exactamente) en la Terminal:

    • sudo nvram AutoBoot=%00

    • Presiona [return]. Si se te solicita, introduce tu contraseña de administrador y vuelve a pulsar [return]. Nota: La tecla de retorno también puede estar etiquetada como ⏎ o "enter".

    • Ahora puedes apagar con seguridad su Mac y abrir la carcasa inferior, sin que se encienda accidentalmente.

    • Cuando hayas finalizado la reparación y se haya vuelto a ensamblar su Mac, vuelve a habilitar el inicio automático con el siguiente comando:

    • 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.

    Dan -

    This did not work when running High Sierra.

    Kyle B - Contestar

    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 - Contestar

    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 - Contestar

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

    Nursat b - Contestar

    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 - Contestar

    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 - Contestar

    Not able to do that with damaged screen

    richardjgreen - Contestar

    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 - Contestar

    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 - Contestar

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

    result: `AutoBoot %00`

    Marek Polák - Contestar

    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.

    Grant Ormsby - Contestar

    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 - Contestar

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

    hatuxka - Contestar

    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 - Contestar

    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 - Contestar

    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 - Contestar

    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 - Contestar

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

  2. Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201, Remueve los tornillos pentalobe: paso 2, imagen 1 de 1
    • Antes de continuar, desenchufa y apaga tu MacBook. Cierra la pantalla y colócala sobre una superficie suave, con la parte superior hacia abajo.

    • Utiliza un controlador P5 Pentalobe para quitar los seis tornillos que sujetan la carcasa inferior:

    • Dos tornillos de 6.2 mm.

    • Cuatro tornillos de 3.4 mm.

    • A lo largo de esta reparación, realiza un seguimiento de cada tornillo y asegúrate de que vuelve exactamente de donde proviene para evitar dañar tu dispositivo.

    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

    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 - Contestar

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

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

    • Aplica un asa de succión a la caja inferior cerca del área central delantera del MacBook Pro.

    • Levanta el asa de succión para crear una ligera grieta entre la carcasa inferior y el chasis.

  4. Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201, Separa los clips: paso 4, imagen 1 de 3 Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201, Separa los clips: paso 4, imagen 2 de 3 Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201, Separa los clips: paso 4, imagen 3 de 3
    • Inserta una esquina de una púa de apertura en el espacio entre la caja inferior y el chasis.

    • Desliza la púa de apertura alrededor de la esquina más cercana y hasta la mitad del lado del estuche.

    • Esto libera el primero de los clips ocultos que aseguran la carcasa inferior al chasis. Debes sentir y escuchar el clip liberarse.

    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.

    • Repite el paso anterior en el lado opuesto, deslizando la púa de apertura debajo de la caja inferior y subiendo por el lado para liberar el segundo clip.

  6. Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201: paso 6, imagen 1 de 3 Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201: paso 6, imagen 2 de 3 Reemplazo de la caja inferior del MacBook Pro 13" Touch Bar 201: paso 6, imagen 3 de 3
    • Inserta tu púa de apertura una vez más debajo del borde frontal de la caja inferior, cerca de uno de los dos orificios de los tornillos más centrales.

    • Dale a la púa un giro firme para liberar el tercer clip que sujeta la carcasa inferior al chasis.

    • Repite este procedimiento cerca del otro de los dos orificios para tornillos más lejanos, liberando el cuarto 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.

    • Tira de la caja inferior firmemente hacia la parte frontal del MacBook (lejos del área de la bisagra) para separar el último de los clips que aseguran la carcasa inferior.

    • Tira de una esquina y luego de otra.

    • Tira de costado no hacia arriba.

    • Esto puede requerir un montón de fuerza.

    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.

    • Retira la caja inferior.

    • Para volver a instalar la caja inferior:

    • Colócala en su lugar y alinea los clips deslizantes cerca de la bisagra de la pantalla. Presiona hacia abajo y desliza la cubierta hacia la bisagra. Debería dejar de deslizarse cuando las pinzas se enganchen.

    • Cuando los clips deslizantes estén totalmente acoplados y las minúsculas parezcan estar correctamente alineadas, presione firmemente sobre las minúsculas para acoplar los cuatro clips ocultos que hay debajo. Deberías sentir y escucharlos encajar en su lugar.

Conclusión

Para volver a ensamblar tu dispositivo, sigue estas instrucciones en orden inverso.

Before step 7: if you removed the clips properly, the panel will move up by quite a bit. make sure it's not flat when trying to pull, because that mean you didn't loosen the clips enough
