After update to 16.12.2 Windows wasn't capable to detect the hardware.
I had to back up for 16.10.1 and for the last update before 16.12 (16.11.5).
I even try to install the Beta driver 17.1.1... Same problem. "AMD Software wasn't capable to find a AMD graphic card".
I think it's a driver problem.
I made the update as every update I made, with the new driver notification on Radeon software and downloading over it. As I hadn't problems before this time, this is why I think is a driver issue.
So... Will this "new generation" of AMD Radeon drivers work on notebook someday?
