SurfaceBook Crashes/Shutdowns During Sleep

My experience is different.. After April update, my SB only crashes when unplugged, and has never crashed while plugged in yet.

I have to say, that my crashes are much less frequent after April update. Now, it is maybe one crash in 10 sleeps or so. Before the update, my SB would crash every second sleep. But I get "hot bag" with depleted battery now and again, which probably is part of the same issue - as SB doesnt sleep properly..

Great summary and is exactly what is happening on my machine. I've done all the SFC repairs and have all the latest updates installed. ARGH!!!

Some clarification and reinstating of facts:

1. SB default power settings: While on Battery, sleep at 10 minute mark and hibernate at 2 hour mark. While Plugged, sleep at 10 minute mark, and no hibernate at all.
2. SB does not crash while in hibernate.

Almost none of the Win10 background process run while in hibernate, therefore no crashes take place.

If you leave SB on battery, the chances of getting a crash is minimum or nonexistent, because after 2 hours it will go into hibernate.

3. SB does crash while in sleep (long period).

Almost all of the Win10 background process run while in sleep, therefore crashes take place.

If you leave SB plugged, the chances of getting a crash is very very high if SB stays in sleep for long period of time (several hours) or overnight.

4. SB firmware got updated first time on 2/17/2016 which modified the sleep state in general (the default power settings did not change).

My SB sleep-crashes started after the 2/17/2016 firmware update. Before the 2/17/2016 firmware update, I never experienced sleep crashes (plugged in) since I got my SB on November 28.

I have concluded that Win10 background processes are the culprit. They do not work properly with the modified sleep state (rolled out on 2/17). The EventViewer (under Windows Logs, System) shows many critical errors while SB is in sleep, most are DCOM errors. Eventually, while sleep, Win10 crashes.

A very common DCOM error (many many of them) while in sleep, is related to InsiderHub and FeedbackApp.

My experience is the same.

I have not changed the default power settings. If I plug in my SB overnight to recharge then it almost always crashes, whereas if I leave it unplugged -- as I frequently do now, for this very reason -- then it almost never crashes. I can't say 100% that it's always in the one case and never in the other but the difference is clear.

I didn't get my SB in the UK until Feb 17 but it didn't start crashing immediately: the first occurrence in event log was on the 23rd, which was a couple of days after the 17/02 firmware update was applied (it didn't come with that, obviously) so that could be the culprit.

Same issue here. I thought the sleep issue was fixed so I got my sb in mid April. But apparently I was wrong. SB crashes almost every time during sleeping. I saw in some post saying the crash is caused by welcome hello camera. I have disabled it but it didn't help. 

I have also tried a lot of different configurations but nothing helps. The only trick I have learned is not to charge it after I close the lid and during the whole sleep. In this case, sb is able to go to hibernation mode after 1 hr (according to my configuration) and will wake up successfully later -- but not always. It happened a couple of times that a login screen is shown up without any place to input password or passcode, which will finally lead to a force restart. 

This crash during sleep thing really bothers me a lot. I am prepared to deal with all the glitches of a new product but I just don't get it why MS can't get this most basic feature right...

So far, it looks like I'm able to eliminate the DCOM errors (http://xlery.com/blog/tag/9ca88ee3-acb7-47c8-afc4-ab702511c276/), but still crashing.
