Laptop shutsdown when suspended to RAM

hi, guys

I have a strange issue with my HP EliteBook 850 laptop. When I close the lid, it goes to suspend, as expected. Couple of minues later, when I turn it on again, it wakes up without problem. But, if I leave it in suspend for some time (like 1-2 hours), and get back to it, it is shutdown. This happens both on battery and on AC power.

I use systemd suspend and powerdown for energy saving. But, since it happens on AC as well as on battery, I'm not sure it has to do with powerdown tweaks. This is my logind.conf file:

[Login]
#NAutoVTs=6
#ReserveVT=6
#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root
#InhibitDelayMaxSec=5
#HandlePowerKey=poweroff
#HandleSuspendKey=suspend
#HandleHibernateKey=hibernate
HandleLidSwitch=suspend
#HandleLidSwitchDocked=ignore
#PowerKeyIgnoreInhibited=no
#SuspendKeyIgnoreInhibited=no
#HibernateKeyIgnoreInhibited=no
#LidSwitchIgnoreInhibited=yes
IdleAction=suspend
IdleActionSec=20min
#RuntimeDirectorySize=10%
#RemoveIPC=yes

I'm not sure if it has to do anything with this issue, but hope somebody has some tips.

Just to rule out weird hardware issues, does this happen on Windows as well (or another Linux of your choosing)?

Do you use catch-all "savers" like TLP, powertop or laptop-mode-tools?

I only have Arch installed on laptop. I use it for work, so I don't like having multiple OS-es.
And no, I only use powerdown. I did use laptop-mode-tools, but it cause some other issues with power management, so I removed it.

Re: Laptop shutsdown when suspended to RAM

Well, I found a solution for this problem. In case someone stumbles on the same problem, it is simple. I commented out these two lines in /etc/systemd/logind.conf:

IdleAction=suspend
IdleActionSec=20min

After this, suspend works fine
