Just another sample-of-1 statistics: XPS 13 9333 owner here, with Windows 10, never had that issue. I've seen it on Windows 7 on my Dell XPS 8500 desktop PC though - and I had gone through all events and devices and disabled any settings that might wake up the system for any reason.
Yoga 2 pro as well. Was common with Ubuntu 15, now it is rare with Ubuntu 16. I used to think this was a straight up Linux / Ubuntu bug, but seeing the anecdotes here for the other major OSs', and for other laptops, makes me think that all laptops have one crazy bad chip that controls power and cooling. Is that the BIOS' job?
