I just installed the Windows 8 Consumer Preview on my ST5112. Everything is working, except for the buttons along the bottom (the power button works, but none of the other buttons). The only one I ever use is the screen rotation button, to switch between landscape and portrait mode. I installed the button driver for Win 7, thinking that would work, but no luck. Has anyone else installed Win 8 on a 5112, and gotten the buttons to work? If not, is there another way to rotate the screen?
