Laptop going to sleep for no reason

Hi,
I am running ArchLinux on a Samsung Serie9 900X3C. My laptop frequently (~10 mins) goes to sleep, but I can't find the reason why.
Here is a pastebin of the output of dmesg and here is a pastebin of the output of journalctl. For example here, around Jan 06 17:24:45, the system went to sleep suddenly for no reason.

According to the logs, no errors occured, so I suspect a user-side program is suspending my computer. How could I know which one triggered it and why?

Cheers,
Corentin

Re: Laptop going to sleep for no reason

What is the output of "upower -d" and "cat /etc/systemd/logind.conf"?

See here for logind.conf and here for upower output.

Through logind.conf you told the system to suspend after 600 seconds of idle, and it does.

The thing is that the computer is not idle, I'm using it when it suspends. However I am going to comment the line and see if it makes any change.

What DE/WM are you using?

Your previous solution solved the problem. I'm using i3. Have you found any report concerning erroneous report of idle time by i3?

I haven't. I have no idea how KDE or GNOME deal with that.
