Hi, I am currently experiencing the same problem. Coincidentally, I have the same model as well. My only solution is that I would go to the "CTRL+ALT+DEL" page in order to login to safe mode or to simply shut it off then plugging in the charger. Afterwards, I would turn on the laptop again and just unplug it afterwards. Sometimes, it would work, sometimes it wouldn't.
Usually, I will encounter this problem after I would update the GPU Drivers to the latest or after I tinker with the GPU control panel to set my extended monitor.
Hope there would be a fix for this problem as it is very inconvenient and annoying especially when I am working.
