Sostituzione Schermo MacBook Pro 15" Touch Bar 2017

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?

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

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.

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.

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.

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.

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

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.

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.

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.

I did not have the magnetic project mat, but instead I stuck loops of blue painter's tape on the table, wrote the step number on them in sharpie, and stuck the screws/covers for the corresponding step on them.

If the battery you are replacing is swollen and you do not know it is - swollen, Watch out!

You may strip threads on some of the screws. Rotate the unscrewing as in a clockwise - counterclockwise manner if some of them start to feel tight.

I like adrianbrown's suggestion. Spot on!

Its difficult if the side catches arent released properly, check them again if it seems too much.

I snapped one of the spring loaded logic board grounding pins. Take your time. Leverage from the back in order to push it out versus pulling on it.

Take the opening pick and stick the edge down behind the hinge all the way to one side, so it is perpendicular to the case, and give it a twist. That end should pop free. Do the same on the other side and there you go.

Thanks Indawg Wetrust, Made it very easy!

They, iFixit, are not kidding. Quite a bit of force needed.

This step requires a lot of force to slide the back cover away. Make sure you get a good grip of the mac body and of the back panel.

It helps if you know what the mechanism inside the case looks like, try to find a picture and imagine pulling out those prong things, also if you understand this mechanism, you can more easily put the case back on!

I literally cut myself with the bottom case, when it finally got freed from the upper case. I have opened a lot of macs, phones, and other items in my life, this was a first. Some light duty cloth gloves next time.

I didn’t understand some suggestions above. Tried Indawg Wetrust but didn’t really get it. Now looking back, it means use the pick just on the tiny lip of the cover, close to the hinge. Not on the antenna, but just on th slip of metal I believe. If that can help others.

My Macbook doesn’t appear to even have this piece.

This cover is not attached to anything critical underneath, so do not be afraid that you can break anything like pulling anything from the mainboard. Just pull it out. To reattach, I removed the old double side adhesive tape and replaced with fresh one.

I was able to reinsert the cable easily a number of times with the nice Ifixit angled tweezers as the ziff connectors tiny latch came off! I ended up using a bit of Pliobond 25, contact cement to mke sure the data cable doesn’t move. A future repair will just pull off or at most need an xacato blade knife to slit the rubbery cement.

REALLY important. You need to really pull this back in snug for things to work when you reassemble.

I didn’t seem to have any tape covering it, I just proceeded to the next step

My battery board connecter is broken. Let me know where can I get these cables.?

I recommend to just lift a little the right end (end of the cable side), then keep the socket in place with a spudger while removing this adhesive tape, to avoid any accident like ripping off your socket. With a little care, it is safe and easy to remove completely.

lock flap broke when I was about to close it, is there any way to fix it? The computer can't find the battery

I had no issue here but I recommend to use a second spudger to keep the rest of the socket in place while GENTLY lifting the lock. It should lift without effort.

When putting it back, be careful, there might be a little piece of transparent adhesive foil on top of the socket, gently lift it up on the side of the cable. The cable should slide in easily, but do not force it. About 0.5mm of the cable contacts will be VISIBLE on the left side, when the cable is fully it, do not force it more than that.

コネクタのプラスチックが割れたのですが、代替品を教えてもらえませんか？

Same here, I broke the cable which was soldered on the mainboard. I tried to hold it on place with a tape, but I couldn‘t charge my macbook though. Then I tried to solder it and I also failed. I wish I had read the comments before :/

Anybody know where this connected can be purchased? Mine completely snapped to pieces the moment I touched it.

Surprised by the tolerance of this little connector to my mistake of not flipping up the not very noticeable clamping element on side opposite to where the contact tip is inserted. The contact tip pulled right out without having done that. Saw in a video I should have done that before pulling the contact tip out. Remembered when reinstalling it.

The cable is stuck on the board underneath with adhesive, so it is best to first work it a little from left under (as the picture is oriented) in order to break the adhesive, and then pull it sideways. At all times, I kept the socket safe with a spudger to avoid ripping it off the board. The cable will come out with a little effort. Remember, it is the socket you need to take care of, not the cable (the cable will be thrown away with the old battery).

I had issues in reassembly - the lever for the ZIF socket was missing. I think it came off with the tape. I found the lever, but it was way too small for me to reattach (I couldn't hold it well enough with the tweezers and wasn't sure where the hinge pins went).

The computer did not recognize the battery or recognized it with errors (if I got the cable just right) without the lever.

My solution was to cut a tiny bit of electrical tape and put it on the back of the ribbon cable to make it thicker. This gave it enough traction to stay in the socket and pushed the ribbon onto the contacts.

Same problem, any solution?

Lifting up to about 75 degrees is more that enough and safe, and I did also use some electrical tape to block the contact. When this goes back, there is no socket in place, it is just the screw that keeps it there.

I put electrical tape on this as well. Glad I did. "Being careful" during the whole process gets lost when you're focusing on other parts.

T3 worked for me, the T4 I have was too big.

Make sure you pay attention to which screws you remove here! I removed the 2 next to these 2 that hold in that metal plate and then couldn’t figure out why my antenna would not come out!

VERY IMPORTANT to pay attention to the screws in the is step if you don't want to struggle or even damage the antenna

The secret to these is to lightly twist the P2 to make sure it’s fully engaged. Once it is, then push straight down (very very) firmly on the screw as you turn it counter clockwise and it will come right out.

Do the same but clockwise when you reinstall and you won’t strip a thing.

I had a problem using the ifixit tool kit to remove the 16 antenna screws (striped one badly) so i ordered the Wiha drivers from Germany and found the ONLY bit that would fit and thus remove (press down firmly while rotating driver) the pentalobe screws was the 1PLx40 driver, not the 2PL as many have said here. 2PL was just too big to even fit in the screw head.

I had some real issues with these screws. It was because the P2 bit was stripped somehow. iFixit was super helpful!!! They replaced the bit and the new bit worked perfectly. Only stripped one screw. Thanks iFixit!

Oops — deleted my old thread. Posting to leave this link to replacement P2 Vent/Antenna screws: https://beetstech.com/product/vent-anten...

This is a very tough step.

I know well the effective technique to remove these, but occasionally that’s not enough. I found myself in this situation recently. While I do plan to avail myself of iFixit’s lifetime warranty, I also purchased a small set of Wiha pentalobe screwdrivers. The 1PL is the equivalent and the fit is glove-perfect; if you look at the tip under a microscope you’ll understand why. As happy as I’ve generally been with iFixit parts/tools, their P2 *never* fit like Wiha’s 1PL, and you don’t need to push down on these screws to release them with very little effort.

Same problem here. 13 screws came right out, 3 were stuck. I tried WD40 and a little heat with increasing levels of force. My iFixit P2 bit was a good fit for the screws but it eventually twisted and the tip broke off (thanks iFixit team for already sending a free replacement). I bought a Wiha 1PL screwdriver (model 26761, same tip as P2) for $9 on Amazon and that worked like a charm. Back on my way to dealing with the real problem: Flexgate.

I had the 2nd screw from the end on the right(looking at logic board) to strip on me with a kit I use from Kobalt. I spend a deal of time looking for P2 screwdrivers I received with replacing phone screens but they didn’t work. So I proceeded on to see if I could work around it…..WHICH YOU CAN!!! If the screw(s) you have issues with are outer screws you may be able to manuver the hinge cable and display cable around out of/into place. I was successful doing this, you just have to becareful but it can be done without removing the WIFI antennae.
