I have this issue. very long story involving UBREAKWEFIX Samsung repair place. They were unable to repair, came back missing screws, back cover was loose and apparently so was the touch screen. Eventually (2 months late) I plugged it in and it booted slowly with battery but had to be plugged in. Worked fine but then stopped because repair place didn't set the new screen in properly. I was able to use a 2nd monitor (what a pain) using micro-c but that's stopped working now too. It's running (I hear the fans) plugged in with and without a battery but monitor won't work via HDMI port. Same for the micro-c port. I'm flying blind with this thing.
