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.
Huzzah! I ordered a tracked replacement else suffer bricking my MacBook. All is better and I am typing from the machine right now! I will add a comment to the trackpad replacement, but my machine had T4, not T3 screws. I stripped a couple on the removal. In the end, this was more expensive than Apple replacing the battery, but there is a sense of triumph! I was also bitter since Apple had already replaced the keyboard and screen due to recalls. I wanted to DIY this one. Thank you Jeff!
I did try all of those and checked the cables and ZIF connectors under a microscope. I am thinking a bad trackpad now since it works fine, but the keyboard does not respond. The only way I have figured out o use the machine is to disconnect and reconnect the battery, which is not easy. Otherwise, I cannot power it on myself since the power button is part of the keyboard. Apple won’t touch this now since I replaced the battery myself, so it is kind of a brick. I can’t run AHT since the keyboard doesn’t respond (command-D). Any ideas?
Everything worked, except the keyboard. No backlight, no power. Using remote keyboard for now. Any ideas? Trackpad works fine.
