When I hibernate my computer it shuts down ok but then a minute or so later it will boot back up.
It completely powers down and I can even unplug it from the mains and plug it back in. Usually a it turns itself back on after a couple of mins, but sometimes it takes a while longer.
If I hibernate the computer and turn the mains off for say 5 mins then turn it back on, it does not restart itself.
I used to have this problem when I first installed the beta but it slowly went away.
It's a bit annoying that it's resurfaced.
As far as I can tell all drivers
are up to date.
