I did a screen replacement on a Surface Pro 4 no power now
I did a screen replacement on my surface pro 4. In order to get the touch functionality to work I had to disconnect next the battery, after that the machine worked for me but I noticed that USB port had no power, I lifted the screen up and tapped it and the surface powered down, No power ever since, when I connect the charger the light can mess on, but the computer puts no power out anywhere no matter what button can mob I choose, is it a bad mother board? What do I do?
