As many of you have posted the SB will consistently crash at some point during sleep. In my case it had been taking 3-4 hours in Sleep. Recently it started doing it after an hour or so in Sleep. I haven't changed anything. Yes, all updates are installed and I've tried all the potential "fixes" (sfc followed by DSIM using a clean image, disable Fast Startup, turn off WiFi connected while in Sleep, etc.). So back to the MS Store I went. They took a look at the Event log, which had dozens of Critical Errors related to the Sleep crash and hundreds of other errors and warnings. They reviewed the settings and checked the drivers and updates. They have seen this happen before on my multiple SBs. In the past they would say it had to be a hardware problem and swap out the SB.
I want to say that the staff at the MS stores deserve credit for being really great about doing what they can to support me, but it almost always results in a SB replacement that ultimately has the same issues.
This time my visit to the store was different. After confirming the latest SB exchange hadn't solved the Sleep problem they surprised me by suggesting that maybe the SB wasn't the best PC for my needs asking "might I prefer a different PC such as a Dell XPS or Lenovo?" I wasn't sure how to respond. They won't (can't?) say that there are issues with the SB, but trying to steer me away from it when they know I purchased the SB specifically for its features was unexpected and telling. I left the store saying I would think about it.
Has anyone else has had a similar experience?
For now I assume Sleep will fail. So I have turned off Sleep and I shut down the SB when I will not be using it for an extended period. Annoying that I cannot use Sleep, but it isn't a big issue as I don't use the SB for anything but browsing. I won't load my Apps or use it for work until/if the SB shows better stability. I travel frequently so Sleep is critical to my work use of a notebook PC.
