Hi,

Try shutting down again and resetting the SMC: https://support.apple.com/en-us/HT201295.

Resetting the SMC does not slve the problem.

Zapping the NVRAM does not solve the problem either.

Although, since the computer is not recognizing the keyboard, I cannot be sure that it is even recognizing the startup keyboard presses.

i have a MacBook Pro 15" from Nov 2016.

when I power up, the cursor is in the upper left corner, and nether the keyboard nor the trackpad are recognized.

afer a few sconds a Bluetooth Setup Assistant dialog box pops up and "looks for a wireless keyboard."

So I can connect an external keyboard and trackpad, but can't get the Mac to recognize its own.
