Why is my keyboard an trackpad unresponsive? How can I fix it?
I recently purchased a damaged MacBook Pro Retina 15" off eBay (dangerous I know), and everything works great... except the trackpad and keyboard. The power button works, which is a bit odd given the fact that the rest of the keyboard doesn't.
The computer came with a broken screen, lacked most of the internal screws (haven't received the screw set yet), and came with no SSD.
I've replaced the screen, installed an SSD, at which point I found that the keyboard and trackpad doesn't work. The trackpad being one of the Taptic Engine trackpads vibrates, but doesn't do anything else. An external mouse and keyboard do work though.
I ran Apple Diagnostics and found error NDR001, which Apple's site says is related to the trackpad, and to schedule a Genius Bar appointment. (Thanks Apple.... although it may be a good option to at least get an estimate)
I ordered a keyboard and trackpad replacement to attempt to replace them and fix the issues, however, upon receiving them and connecting them, I have the exact same issue. Power button doesn't work, and the track pad doesn't work.
I'm pretty confident at this point it may be the logic board that's messed up, and not the keyboard and trackpad. However, I'm inclined to put the screws in when they arrive tomorrow, to see if that fixes the issues, but I'm not hopeful. Additionally, I've already tried doing a NVRAM reset and a SMC reset, but still not dice.
Does anyone have any ideas as what to troubleshoot next?
Is this a good question?
