yes, this solution solved my problem too just today. Actually this afternoon, i got call from the Microsoft service center and a guy told me he can help me to fix it by remote assistant. he operate from the "Quick Assist" and when he operate, i realized
that what he did is just installed this "Inter Graphics Command"! it's funny right, what they did is a solution originally came from the forum! However it works! The guy told me so far 90% of the "auto-shutdown" cases can be fixed by this method! And this
fix will not change your screen resolution, brightness, etc.
So, Bro "JamesSmith2020", please just call the service center and they will help you to operate.
When the first day i found this problem, i also disappointed and kept thinking of return the unit and probably buy another regular laptop. But i indeed really love the sexy design of this Surface pro and reluctantly to go back! Also, i don't like the IPAD
pro because after all it is just a good entertainment tool rather than a work station.
Just like you said, it is an expensive unit and you choice for a good reason. So fix it and keep it!:)
