I have experienced the same problem. Screen goes black when power cord is connected.

I found that the screen brightness adjustment is reversed.

Try for yourself.

Right click the start menu, open power options, choose when to turn off display, under plugged in adjust the brightness level towards the lower setting and the screen will brighten with power cord connected, save changes and restart.

This worked for me.

Maybe Microsoft need to look at this.
