More details about the symptoms:
Laptop doesn't shut down, the screen is black (but backlit) and there is no mouse pointer.
I can use Remote Desktop to connect with the laptop and all of my applications are still open and functioning. I can log into the laptop (blindly) and type into notepad and then connect with Remote Desktop and see that they keystrokes made it through to the application.
In addition, the screen will randomly "flash" or "blink" for reason I can detect.

I have the same problem with T500, random shutdown, and then flushing for several seconds. VGA seconds monitor also goes black.
However I hear sounds e.g. from whatsApp or FB.
