So my settings are:
Turn off after: 1 hour of inactivity
Power mode: Instant on with wake up xbox and auto updates checked.
My xbox has not turned off though or went into a stand by mode. All it does is dim the brightness after several minutes, but won't turn off. I left it on Netflix over night as I fell asleep watching a movie. When I turned my TV on my xbox was still running Netflix. I left it on the dashboard/home screen today for two hours as I went out and came back and it was still on the dashboard and lit up brightly as I walked in front of the Kinect.
Am I not understanding the settings or does this not work? I don't want to be forced to leave my Xbox on 24/7 or over night every night when I watch TV as I fall asleep.
