My SB with all latest drivers successfully installed still crashing in sleep :(
For me, the latest update also brought back "hot bag" issue - SB for no reason gets hot, turns fans and depletes battery real fast while in "sleep" mode. Sometimes it depletes it to 0, so the book shuts down (properly) due to no power, sometimes it crashes before. This "hot bag" was fixed for me with February update and now it is back again.
On somewhat positive side, Hello camera seem to be working fine with hibernation. So, I guess, I have to go back to "always hibernate" mode..
Most frustrating is how Microsoft handles these issues. There was a long thread on this forum "Surface Book Shuts Down During Sleep after 17/2/2016 Firmware Update", they deleted it without any response that I saw.
Have anyone heard anything from them at all on issues we are having?
