On Fedora 22 cleanly installed, this is what I see in Settings > Power: Automatic suspend: Off When battery power is critical: Hibernate There are no choices, those are fixed settings that I can't change. The actual behavior I see when the battery gets critical though, is suspend, not hibernate. First there is a message the machine is about to be hibernated, but then: Sep 27 02:45:38 f22m.localdomain systemd-sleep[4960]: Suspending system... I get the same results with Fedora 23, with one exception in Settings > Power "When battery power is critical: Hibernate" is not listed at all, just that automatic suspend is off. Anyway, the system suspends, but there is no battery power so the suspend to RAM is lost, and it's entirely possible if not likely that there will be data loss or fs corruption as a result. Also cc'ing test@ because I'm not seeing a test case for this. It seems to me that out of the box we shouldn't be risking people's data like this, but it's not like poweroff -f is a whole lot better (except for the fs portion). -- Chris Murphy -- desktop mailing list desktop@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/desktop
