One note on that. I've had Sleep of Death in even the most minimal scenarios. The SB is my second computer so 90% of the time I'm just in my browser.
I've had SoD with just Edge open with on tab. And in fact, one time after a SoD I started up the computer, logged in with Hello and then just left it without opening up any applications. I returned to the computer later in the day and it SoD'ed. So I don't particularly believe it's simply a problem with rogue applications not being compatible with the sleep states. It's certainly possible. I do have Java installed on this machine and I'm sure it runs that dang update check process periodically in the background. That's the only non-MS process that would have been running on a fresh boot.
