Hi,
I have a https://wiki.gentoo.org/wiki/Lenovo_IdeaPad_Yoga_900_13ISK
the S4 (suspend to disk /hibernate) was broken because the wifi module was no more maintained by intel's linux dev.
so I upgraded to
01:00.0 Network controller: Intel Corporation Wi-Fi 6 AX210/AX211/AX411 160MHz (rev 1a)
Subsystem: Intel Corporation Wi-Fi 6 AX210 160MHz
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at a1100000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
and followed the https://wiki.gentoo.org/wiki/Suspend_and_hibernate
after changing grub configuration, changing dracut configuration to handle boot from image I got the S4 working when performing `loginctl hibernate`
BUT I can't make the system enter hibernate on low battery
I tried to start upowerd making openrc script (so now upowerd is started on boot) and upower command reports

so is working... buuuut.....
when battery critical level is reached, the system poweroff, and never hibernate....
so, there is something that monitor the battery, and poweroff the system (no dirty "off", services are stopped, disk umounted....) and this is not upowerd that do the work.... I suspect upowerd not working outside systemd, and really prefer openRC, so... what is performing power management on openRC systems? what is too bad with upowerd, is that the command to hybridsleep can't be specified (so can't take advantages of advanced features of https://github.com/bircoph/suspend like image encryption....)
thanks and regards |

To reply myself, might help someone....
I ended doing it in a script that I launch in screen at login
| Code: |
$ cat ~/.local/bin/battery_monitor.sh
#!/bin/sh
criticalLevel=20
battery=$(upower -e | grep battery)
while true; do
sleep 2s
BatteryStat=$(upower -i ${battery})
state=$(printf "%s" "${BatteryStat}" | grep state: | sed "s/[[:space:]]\+state:[[:space:]]\+//")
if [ "${state}" == "discharging" ]; then
percent=$(printf "%s" "${BatteryStat}" | grep percentage: | sed "s/[[:space:]]\+percentage:[[:space:]]\+//;s/%//")
if [ ${percent} -lt ${criticalLevel} ]; then
loginctl hibernate
fi
fi
done
