I'm on my second Surface Book 2 and after 3 months of using it I'm having the same issue with the new one. This new one is even worse now, at times it will display screen is detach and displaying it's not being charge when the power cable is connected. My first Surface Book when I took it into the store they didn't even look at it, I just told them the issue and they just gave me a new device. Come on Microsoft fix the issue!!!!!!
Just in case you think it's a user issue Microsoft, I do tech support for a living. I deal with your issues everyday at work and now I have to come home and deal with it also. What a joke!!!!!!
