Im purchaded few weeks ago Laptop Asus ROG Strix GL503VM with windows 10 64bit. its nice stuff But Numpad keys wont work in games and programs. But outside games and programs works correctly. Did anybody knows why is this happening? Yes! Nunlock key are ON, Im 100% sure there no any virusues or some ugly stuff. i guess maybe WIndows 10 something blocks. Because in my old laptop Samsung RV510 with 7 everything works fine.
