-
Remove the following ten screws securing the lower case to the upper case:
-
Three 13.5 mm (14.1 mm) Phillips screws.

Carefully lift the logic board assembly from its left side and work it out of the upper case, minding the optical drive cable and the I/O ports that may get caught during removal.

If your doing this just to replace the keyboard. the keyboard can be replaced after this last step. I found one for $16 on ebay. the only challenge is removing the backlighting which is taped down and then unscrewing about 50 tiny screws to remove the keyboard. the above process takes about an hour and then another hour to just replace the keyboard.
Hi there, I replaced the keyboard on my MacBook pro 15'' mid 2012.
Now my computer turns on but shuts down after a few seconds, except if the charger is plugged in. Do you have any idea what I might have done wrong?
I already did the process 3 times 😥
Thanks,
Marta

I completed this replacement successfully, with one glitch and two leftover items. The glitch: I failed to insert the keyboard ribbon cable at first. The leftover items: A multilayer soft pad, silvered, about 3x1 ¾-(7.5x4.5 cm) and a piece of foam in a quarter-round shape, 7/16”(1.2 cm) long, ⅛"(3-4mm) ,on a side, with a fine metal mesh on the long sides. I don’t recall in which step I removed either part. I’m hoping neither is critical, but I’ll replace either as best I can if I’m wrong. I have a photo of the two parts but I don’t see how to add it to the post.
Took me a little over 4 hours, but seems successful. Most of the middle row on my keyboard had stopped working, I was having to use an external. The new case works fine. The hardest part was definitely the logic board removal, but just be patient and methodical and use the spudger to loosen the adhesive that binds the microphone to the upper case. I also encountered two screws that stripped when unscrewing, and had to use some creativity to release those parts. 48 hours after replacement, everything is working, and the new keyboard is definitely an improvement. Time-consuming and stressful but so much cheaper than authorized repair.
