Came in with the power source damaged. Not the cord, but the back of the tower. I turned it on, heard a “fizz” and it shut down. Turned it back on, wiggled the cord at the base of the tower and it shut down again. I know it’s refurbished, but it’s seems like they would have caught this quickly when inspecting it. Oh well, return has been made and I’ll try one more time. Maybe it was just a fluke.
