I have a Lenovo P51 laptop running Windows 10 and I keep having an issue where my screen goes black, the keyboard is still lit up (num lock light is on), but doesn't do anything. I can't even turn off num lock. The only way to get my computer computer to work again is by does a hard reset (holding the power button). This seems to happen pretty randomly. Sometimes the screen will go black after 5 mins and sometimes after 20 mins. One interesting details is that when I am using an external monitor with a Lightbridge USB 3.0 adapter. The computer seems to operate normally. I have checked the Windows logs in Event Viewer, but I haven't found any details of value.
Does anyone know what could possibly be causing this?
