After updating to Windows 8.1 the autorotate function doesn't work anymore: in the setting panel (sliding from the right side) above the brightness slider I see the lock icon, but if I tap it nothing happens. Autorotate doesn't work even if I set it enable from registry or from the display settings.
I tried to install the latest HD4400 Intel drivers, solution I read worked for other people, but still I can't activate it; any ideas about how can I solve this issue?
