Screenshot or video: ======================== Detailed description： When I closed my MBP lid and disconnected the monitor, and closed the folio, in 10 minutes I was not able to do anything with the screen. Controls do not work. The screen seems to be frozen in ambient lighting and the power button is green. Holding power button or menu and power button does nothing.
