Suspend problems on a HP 8470p

I recently got a used HP 8470p that works perfectly well, and I put an SSD I used to boot externally on two machines inside it, and it works fine. I'm not very familiar with logind or anything to do with suspend and hibernate since I never really used it, but I edited my logind.conf to look like this:

Hibernating works fine by using `loginctl hibernate`, but `loginctl suspend` says this:
Code: [Select]
Failed to suspend system via elogind: Sleep verb "suspend" not supported
And the strange thing is `echo mem > /sys/power/state` suspends the laptop just fine... and it resumes instantly when i press the on button. Anybody know what to do?

Try this change, need reboot the system.

Code: [Select]
SuspendMode=s2idle

In my system, I have the entire [Sleep] section commented out. The default value work fine.

Thanks! That worked... but it appears that when I when I close the lid the system does not suspend (there's a wifi status indicator that turns orange when I suspend, but that doesn't happen when I close the lid)... any idea why?

Try,
Code: [Select]
SuspendMode=s2idle shallow deep

In addition, if you have any power management apps like xfce4-power-manager running in the system, you also need to change it to suspend when lid is closed.

Nope, editing suspend mode again does nothing, only the display turns off, just like before
I only have bspwm installed and I have no other power manager app running apart from tlp...

Also another question: what does `shallow` and `deep` do?

I noticed a recent change of behaviour with regard to suspend: having a certain process active (in my case, mpv) made the kernel to refuse suspending, which is absurd.

hmmm I also noticed another problem. KDE Neon recognises the lid closing just fine, and suspends "properly": as in, all the LED status indicators turn off apart from the power one, which flickers every few seconds (the behavior under Windows, i.e the "proper" behavior). Is this a problem with using OpenRC or something else?
EDIT: also forgot to mention that if mpv is running, it suspends "just fine", but then again, my system doesn't seem to actually be suspending.

Power LED "breathing" is the regular suspend behaviour. You can change the lid-close action in /etc/elogind/logind.conf to hibernate or power off.

This is pretty late, but I solved this problem by looking into the manpage of logind.conf: I changed suspend mode to 'deep', which does the expected behavior for suspend (e.g all LEDs turned off, power LED flickering), but handling the closed lid is really hit or miss, and seems to work less than a third of the time. Another strange thing noticed now, though: I put these two lines in my logind.conf
Code: [Select]
IdleAction=hybrid-sleep
IdleActionSec=2min
but it seems that my system hybrid sleeps regardless of whether I'm idle or not, and has hybrid-slept two times already while writing this message. Did I do something wrong?
EDIT: aaaaand it suspended another time while submitting this message.
