Keyboard / Trackpad not working in Mac OS, but works on boot screen

[Siddig]

Have an issue with Macbook Air 13 820-000165 (Mid 2013). Both trackpad and keyboard work fine on the boot screen.
Tried clean re-install (Yosemite and El. Capitan) - no difference. Actually even during installation, input works fine on the boot screen, but as soon as Mac OS setup loads, both keyboard and trackpad stop working.



SMC and PRAM resets didn't help.
