Suspend / pm-suspend not working - Blank screen

Hi everyone, I'm new on the forum.
I decide to make this post because I couldn't fix the problem with any workaround I've found on the forums.
I have a Lenovo Z40-70 (I7, Nvidia GeForce 840m) and I'm using the nouveau drivers.
So, the system suspends when I close the lid but goes blank when I want to wake it up. I've tried with the pm-suspend and in this case the screen freezes after waking it (the display shows as it was before suspend). I followed up the troubleshooting guide on https://wiki.archlinux.org/index.php/pm … leshooting without success. Also I added this hook https://wiki.archlinux.org/index.php/pm … om_suspend (I installed vbetool).

Any ideas to solve this?
Additional information:
4.10.5-1-ARCH
linux-lts installed
pm-is-supported --suspend shows nothing

I will provide any log or command output that could help to solve this.

Best regards

Are you using systemd or something else?  Try

systemctl suspend

Are you using systemd or something else?  Try

systemctl suspend

Same result as pm-suspend, system freezes.

I have no error on /var/log/Xorg.0.log or journalctl
