Suspension not working

On Arch Linux on Dell Latitude 7480 (Intel i5 7th Gen) the suspension features works when i close the computer, and it wakes up when i reopen it.

While on Ubuntu LTS / Debian Stable everything worked as normal, but on Arch when the computer is suspended the display’s backlight is on and there’s a probability that the CPU isn’t in an idle mode beacuse the fans remain pretty loud.
This obvioulsy drains the battery, making imossible to really suspend the computer.

Any help?

(Note: I'm new to Arch, but not to GNU/Linux distros)

Re: Suspension not working

Which kernels do the "works as intended" distributions use and which are you using now? Could be a regression there, test e.g. linux-lts to check whether it might be a regression there.

Re: Suspension not working

Also please post your complete system journal for the boot after attempting an S3:

sudo journalctl -b | curl -F 'f:1=<-' ix.io
