On drivers 572.47 and 572.60 drivers, when advanced optimus automatically switches to the dGPU, the laptop will remain at a black screen. Can only power down or force reboot to restore normal operations.
If you manually switch to the dGPU before starting a game then the screen wiill remain normal.
@Admins can we get this escalated to Nvidia
There have been many reports from Reddit on issues with the 572 drivers eg
