Hey guys, so I have decided to return my Surface Book, the announcement was only for Surface 3 and Pro 3. I think an issue like this should have been at least addressed properly by Microsoft. This device is downright beautiful, but so many bugs (including this one) have killed my interest in keeping it since I don't know when there will be a fix. I hope they release a patch soon for all of you who had invested in this product.
From what I read, you should be aware that you are currently going to find the same problems with any manufacturer using the latest Intel Skylake processors.
The only two problems I have left are "Battery drain while shut down" and "sleep - heating". For me I'm able to eliminate both problems by simply "completely" shutting down. So for me I essentially have no problems, just a slight inconvenience. I've not seen anything else out there that measures up to my Surface Book for what I want in a computer.
Good luck with whatever you decide to do.
