Yesterday I got my new SB, I haven't really installed much, mostly office and project 2016, and did a full Windows Update as well. I left the SB last night around 1AM in Sleep Mode with many apps open, Edge, Outlook and Explorer. This morning around 7AM I opened and to my surprise the SB was rebooting from a Shutdown, after checking the logs in Event Viewer I found "The Previous system shutdown at 3:26AM on 11/26 was unexpected", "The system has rebooted without cleanly shutting down first....." and "The computer has rebooted from a bugcheck.......". I've read all over about this issue called "The Sleep of Death" on the SB, I thought this problem would have been resolved already, it is almost 18 months since the release. Any idea if there is a fix? For me stability and reliability are the two most important attributes of a laptop/tablet device, when I open it, it has to work, at least most of the time. Thanks for the feedback. I am thinking on returning it but I want to give it a try first.
