Swift 3x random unclean shutdown instead of (or during?) suspend

Has anyone else seen this issue with the swift 3x?

Sometimes, after I put my laptop to sleep (by closing the lid), the next time I try to use it, it does a clean boot (all running apps are closed etc...)

The event viewer shows that there was an 'unexpected' shutdown.

It's not clear to me if this happens right at the time of suspend (e.g. if it crashes when going to sleep), or if it occurs at some time after suspend (e.g. crashes whole its asleep).


9/10 times it will resume from suspend (or hibernate) without issue, but once in a while I see this issue where there was an unexpected shutdown and it does a clean boot.

The issue seems to only occur when the laptop is asleep on battery, I don't think I've ever seen it happen while the laptop was plugged in.

There's always plenty of battery life left when the issue occurs though, and I don't think it's a hardware issue, as I've never seen an unexpected shutdown occur while using the laptop. I can use it for hours on end on battery without issue. The issue only occurs with sleep, so it seems like it would be a driver or BIOS issue.

I've tried the following:

- Disabling hibernate

- Disabling Fast Startup

- Disabling UEFI Fast boot

- Internal battery reset

- I noticed a bunch of messages from the intel wifi driver in event manager, and came across this thread which sounds very similar to what I'm seeing (except I'm not getting a bluescreen, I'm just seeing the unexpected shutdown): https://answers.microsoft.com/en-us/windows/forum/windows_10-power/constant-wifi-adapter-activity-during-sleep-then/098e81fa-fc07-4b25-a827-27e17cf0f82c

I tried updating my intel graphics driver as suggested there, but it didn't seem to resolve the issue
