MacBook Pro 2017 13" mit FN-Tasten Display tauschen

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>

Before any repair is carried out that involves removing the bottom case, the machines auto-boot function has be disabled. This can be disabled via the terminal command “sudo nvram AutoBoot=%00” once the repair has been completed the auto-boot function can be re-enabled via the vermin command “sudo nvram AutoBoot=%03”.

I recommend that you have an organizer tray for all the small parts, and label it in advance with the numbered “step” associated with each removal of screws and other parts. It really helped me when I needed to put everything back in reverse order, after the new battery is glued in place.

Finished the repair last week. Some key comments that helped me:

- Step 12, Robert

- Step 13, MikeG1

- Step 13, Rick Jaffe (take a photo when disassembling)

Also added some own comments on Steps 15, 18, 22

To replace the bottom just line it up just like it came from the factory. Make sure it clears the display connectors. And press firmly down until the clips connect to the bottom again.

My 3rd and 4th clips released simultaneously with clip 1 and 2.

Therefore I was looking to do something which had already been accomplished.

yeah be sure not to bend those clips by the display bottom. You pull towards yourself to get it off

I initially tried shifting the whole panel off the front after using the separating tool to make some space at the back where the hinges are. I only had luck when I pushed the panel back to it’s normal state and using the separating tool again to open the front, then getting my fingers underneath the slide it off the front was easy. I guess the lesson is to not use the separating tool to “push from the back“.

This step really through me through a loop. My last two MBP were a 2011 and 2013 and on those the bottom just lifted off when you removed the screws. The clips and this sliding lock design added in the 2017 model was frustrating the first time. I was following a youtube video first and he did not explain the sliding part at all. I should have come here first, this guide explains it pretty well. The second time I opened my 2017, I kept an “opening pick” between the bottom panel and the body on each side, and used my two smallest screwdrivers as levers in both “front” corner screw holes. Used the same method without the picks to put it back together at the end. Wayyy easier that trying to grip the panel or laptop body. Just make sure the screwdrivers/pins that you’re using as levers are small enough to be loose in the screw holes and have room to move

I used the green prying tool in the air gap at the rear to nudge the bottom forward.

That is far easier and more reliable.

David. I agree. I've found the blue iFixit prying tool most helpful. I place it with the curve of the tool around the hinge and move the bottom case towards the front to release it from the slide-in clips. I consider myself to have pretty good grip strength but I have had some bottom cases that just wouldn't budge until I used this method. Scott The Mac Doctor 

once the tape's back in place, it doesn't look tightly attached. not sure, did I do something wrong here or it should be so.

The tape will likely not adhere as well as when it came out of the factory. This isnt an issue! As long as the tape is in place when the lower cover is put back on the device you should be good to go.

The underside of the tape is not uniform. Therefore, pay attention to which direction it is placed by looking at the underside when you remove it. Possibly mark one edge so that you can replace in the same direction during reassembly.

There is no replacement for this cable in the new battery, is this normal?

If this ribbon comes off on both ends, how do you re-attach

the cable connector (where the twizzer tip is) should be cleaned with alcohol or acetone before insertion because the cover (where the tip is holding it back) will have glue deposit smeared on top of the connector circuit traces. Glue will prevent a good connection with the BMS.

The little tab that you pull back on, at least in my cable, was simple glued onto the rest of the cable. I tried to carefully remove the cable, and the tab came off. I did not have flat tweezers in the ifixit replacement kit and did not want to pinch the cable with sharp instruments. Therefore, be extremely careful when removing the tab as it is difficult to reattach the cable without it.

Same problem with the tape coming loose and the cable not coming out. Go further back along the cable and pull gently on the cable with your fingers and the connector will come out easily.

The new battery I received did not come with the battery board data cable, so I had to remove the existing one and transfer it. The lock at the smaller end is the same mechanism as the one at the end shown in steps 11 and 12, but smaller (and harder to see. It helps to gently straighten the left end of the cable before trying to insert it in the end of the replacement circuit board.

I can corroborate MikeG1’s comment. My battery came without the long data cable as well. I had to remove it from the fried battery. Plastic lock tab mechanism on the ZIF connector is smaller. My inspection microscope helped to transfer the cable to the new battery board. Thanks Mike!

Likewise - the new battery came without a data cable. The cable was successfully removed from the old battery assembly and installed on the new battery, but it was tricky and nerve-racking (the cable is delicate and the connectors are very small) without instruction provided! The instructions should be updated to highlight the missing cable possibility, and provide information/illustration on transferring the cable.

When the battery management “BMS” circuit board is re-installed, loosely install the two 3.7 mm screws, put a spudger on the left side of the BMS board to wedge theBMS board to the right then tighten the two 3.7 mm screws. The reason for doing this is that the two power traces on the board may not make physical contact with the battery connector (connector at where the spudger is on step 15). One clue that you didn’t have physical contact is if you reinstalled everything but there is no power unless the AC supply is plugged in (with battery meter on the top at 0%). This was what happened to me. The reason is that when you bend the battery connector in step 15, it’s no longer in alignment with the traces on the BMS board and hence, you have to shift the BMS board to the right to compensate. Once I did this, voila 64% power.

On disassembly note the position of the connector before you lift. It has two gold-plated connections on the underside. On reassembly these need to make contact with the matching battery board connectors. Bending the connector out of the way deformed it a bit, and on reassembly I could see that the connectors didn't align well with the board's connectors. I needed to adjust the battery board position to the left a bit by loosening the 3.1 mm screws in step 23. Possibly this could be the reason why some people report that new battery is not detected.

Be careful tightening these screw. Overtightening will shear the heads off of them.

When reinstalling the plastic hinge covers, be sure to slide the bottom portion UNDER the rim of the unibody. If not when you go to reattach the bottom, it will not fully mate to the body.

For me, the left one (on image) are T3 and the right are T4! haha… I’ll put a pic here to show you guys LOL

These are also T4

I had a hard time getting a T4 bit to go into the one on the left, T3 worked perfectly. The one on the right the T4 bit fit just fine.

Impossible for me to take out these screws.

It actually clicks on and off—I did not pay attention when installing the new monitor and when I went to start the computer the screen did not have power but the bottom half came on (the hard drive fan went brrrr) this connector was down—but I had not “clicked” it on. It can be installed such that it will stay on without the metal strip that goes across it. The metal strip seems to be just to ensure it *stays* on. You got this!

These are mirror images of each other! Beware! In the photo you’ll see that in reassembly the “extra” metal bit goes toward the front. If you look at the underside of them you’ll see two foam bits: one square one to go over the flat metal part, the rectangle over the cable. With the extra metal bit toward the front (away from you) be sure you have the correct cover on the correct side!

Isn't it better to remove these two covers during reassembly to have less friction?

I cannot find 1.1 mm P2 screwdriver heads, only 0.8mm and 1.2mm P@s seem to be out there…

Un reassembly, DONT OVERLOOK the placement of the “Board Flex Cable” from step 19. Make sure you don’t leave it imprisoned under this assembly. It needs to be lying over all this assembly.

When reinstalling the antenna cable assembly, on the front side of it facing towards the trackpad, there is a flat silver piece of metal. It needs to go into a little track in the MacBook. If it doesn’t, things will seem normal until you go to close the lid, and you will get a click.

These are T4 not T3

YES, on reassembly it is possible to turn rotate the cover springs so that the ribbon is toward you. That’s wrong! It should lie down flat in the well of the laptop body. Be sure the ribbon is going DOWN and not draped up.

4 + 2 + 2 =8 screws

There are in fact only 6 screws on the bottom case .

During reassembly remember that the screen goes AWAY from you (as in the picture during removal). My cable was taped to the front of the display and had to be untaped and draped backwards over the bottom edge to get into proper position for attachment. Also, just in case this happens to you, too, the longitudinal rod that carries the springs and hinges was about 0.5mm too long to fit into the recesses. I had to file the rod down very slightly to get it to fit.
