Neither systemctl suspend nor pm-suspend work

Question

Hi everyone!
I am experiencing an odd situation here: my laptop does not wake up when suspended, nieither systemctl suspend nor pm-suspend work. The following happens: it goes to sleep, but when resuming, it simply reboots.
But the funny thing is that pm-hibernate works perfectly.
I have tried everything:
systemctl + laptop-mode-tools
acpid + systemctl
acpid + pm-utils
acpid + pm-utils + laptop-mode-tools
pm-utils
pm-utils + laptop-mode-tools
everytime is a failure: my laptop does not wake up. And journalctl does not say anything illuminating.
Of course, gnome-power-manager is installed.
Is there any configuration or something that I am supposed to be aware of?
Any suggestion?
Thanks in advance!
best regards,
and-bnk

I don't know about pm-utils... I don't think it would actually be in charge of shutting down your computer on its own. I have pm-utils installed but it never caused me any grief like that.
systemd can handle shutting down, suspending, hibernating, maybe some other things. It decides what to do and what not to do in response to various button presses by looking at the file /etc/systemd/logind.conf. If you want systemd to stop handling power, then here is what I did on my system:
1. Back up /etc/systemd/logind.conf.
2. Uncomment the lines in that file that say "HandlePowerKey=", "HandleBlahBlah=", and so on, changing their values to "ignore" (for example, "HandlePowerKey=ignore". This prevents systemd from taking action when these buttons are pressed.
3. Uncomment the lines that say "BlahBlahIgnoreInhibited=", and set them to yes. This prevents programs from telling your computer not to suspend and so on.
You might have to reboot. I don't know when logind sources that file.
Here is mine:

HandleLidSwitch=ignore

Modify according to your needs. And then set up your acpid. Make sure that's running, and write your /etc/acpi/handler.sh . Here is a link that can tell you how to do it: https://wiki.archlinux.org/index.php/Acpid
Hope that helps.
