This is driving me nuts. I've had a SP1 and SP2 which I've successfully used to commute and work with, using sleep or hibernate to hold the things I'm doing then carry on when I'm travelling or back at home/back at the office. With my SP2017, maybe 50% of the time when I resume my system its a fresh boot and everything is lost and not restored/resumed. Previously i put this down to some overzealous sleep settings so when i press power button or choose my 'shutdown' this does a hibernate. but i often fail to get a resume from hibernate when i power up again. Am i doing something really dumb?.. even if the power button was pressed while in my bag, wouldnt the 'hibernate after 10 mins on battery' setting put it back to hibernate not wipe the whole session?.. grrr...
