Hello, I have searched already for answers to this problem and everthing points to changing the power management settings, which I have done. I have set my power manangent to sleep after 10 min unplugged and 30 min plugged. But nothing changes the behaviour of the device. It keeps blacking out the screen after 2 minutes. When I am watching youtube media for example via the Internet Explorer App. So that would also rule out the cases where it is an incorrectly programmed app that is not calling the screens API. Does anyone else have this problem?
