Well, I spoke too soon about the second port not being a problem. It dropped hard just a few minutes ago.
I have my system hooked up to a Startech docking station, so I run 2 additional monitors, and it has a USB3 powered hub and ethernet on it. I was installing Battlenet onto the drive, and boom. It dropped. I lost my keyboard, ethernet, but surprisingly, my monitors were still on... I had to undock and redock the screen to get things back.
It's consistent now too, if I attempt to install Battlenet, it drops at 89% each time.
I then pulled out my hard drive dock, and plugged my drive in, installed Battlenet, and it worked...
I'm trying to figure out how I'm going to try and explain this too... I'm really starting to lean toward the return and wait till Surface Book 2... I really like what this machine can do, but these bugs and the constant fighting I have to do to get the machine to do what I want is really starting to wear on me.
