Still shutting down during sleep? Ugh.
Well, I just had a different issue entirely. For the first time ever, my Surface Book "hotbagged" without a bag. I closed the lid of my SB (set to sleep and then hibernate after 2 hours) just before 7am this morning and left it on my dining room table, as always. At noon, when I went to open it, it was quite warm and of course, refused to wake or boot with a single power button press. After a long press of the power button (force shut down) and then a subsequent re-start (single power button press), it boots normally. And it has only 30% of the battery left. ARGH. Frying pan to the fire. I'd rather go back to the previous firmware that intermittently shut down when sleeping then find that within 5 hours, my SB can get hot and drain the entire battery while sitting closed on my dining room table.
There is nothing in the windows system logs to indicate that anything was running during that time ... literally there are no logs between just prior to 7am and noon when I forced the shutdown/cold boot.
*sigh*
