Trackpad clicks, OS does not register
I had to replace the display on my 2015 MacBook and that went smoothly but as soon as I plugged in the power cord to boot, it seems as if my entire OS was reset because it now only shows me the Choose Language display screen. The problem is that now, my keyboard and trackpad does not work whatsoever. I'm pretty sure the ribbon cable is connected properly to the logic board because the force touch trackpad clicks properly, indicating that its receiving power at least but the keyboard and power button do nothing when interacting with the operating system. I am very desperate for help, because I need my computer working by tomorrow.
Is this a good question?
