MBP, El Capitan - Keyboard not working, but I can get to safe mode? My keyboard is currently not working (literally nothing appears on a password screen when I start typing, both in safe mode and in normal mode). I am currently typing this on an external keyboard. I have tried:


NVRAM reset
SMC reset
Removing the password from the password screen
Trying another user account, no go.
I would really prefer not to wipe the system. 


I just want to know if this is a hardware thing or just a software one. I would like to believe that it's just software because I can get to safe mode (pressing Shift), do NVRAM reset (ShiftOptionPR), and get to the recovery partitions all on the internal keyboard. 

How can I fix this? 

Update: Hardware diagnostics (pressing D on the internal keyboard whens starting the machine) did not find something wrong with they keyboard

Update: I don't think this is a duplicate of Keyboard key stuck or not being recognized; how to fix as I am able to boot to recovery/safe mode.
Since the hardware diagnostics test did not find anything wrong with the keyboard, this is more than likely a software glitch. 

Take your laptop into an Apple Store, they always help out with things like this.
