So that's why mine works. The output includes this line: critical-action: HybridSleep
I do wonder what starts it up. The service is disabled although the default is enabled and I didn't manually start it.
I'm getting curious about your settings, if that's not too intrusive: mine are, with comments removed:
-----------------------------------------------------> % grep -v '^#' /etc/UPower/UPower.conf
[UPower]
EnableWattsUpPro=false
NoPollBatteries=false
IgnoreLid=false
UsePercentageForPolicy=true
PercentageLow=10 PercentageCritical=3 PercentageAction=2
TimeLow=1200 TimeCritical=300 TimeAction=120
CriticalPowerAction=HybridSleep <------------------------------------------
IIRC when the battery was 0 a few days ago, the battery LED (here: the Power On/Off button) started blinking fast, but no sleep was started. Weird ...
The documentation for upower seems technichally to be missing on F26 - so I have to guess whether Time{Low,Critical,Action} values actually mean minutes or seconds ...
Archlinux has some documentation: https://wiki.archlinux.org/index.php/Power_management#Hybrid_sleep
And that looks really interesting: https://www.kernel.org/doc/Documentation/admin-guide/pm/sleep-states.rst
This latter page - after a glance on it - seems to suggest that sleep modes are organized by the kernel, via three files. Here, they look like so: ---------------> % cat /sys/power/mem_sleep s2idle [deep] % cat /sys/power/state freeze mem disk % cat /sys/power/disk [platform] shutdown reboot suspend test_resume <--------------
