don't sleep on low battery

Hi.
When battery is low, my laptop goes to sleep. I use the laptop as a server and when power restores, the laptop won't wake. How to disable it?

I have xfce, but in its power manager/system it says:
on battery: never
on critical battery: do nothing

Re: don't sleep on low battery

What are the contents of  /etc/systemd/logind.conf ?  Check that the power management functions in there are configured.

[Login]
#NAutoVTs=6
#ReserveVT=6
#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root
#InhibitDelayMaxSec=5
HandlePowerKey=poweroff
HandleSuspendKey=suspend
#HandleHibernateKey=hibernate
HandleLidSwitch=ignore
#HandleLidSwitchDocked=ignore
#PowerKeyIgnoreInhibited=no
SuspendKeyIgnoreInhibited=no
#HibernateKeyIgnoreInhibited=no
#LidSwitchIgnoreInhibited=yes
#HoldoffTimeoutSec=30s
#IdleAction=ignore
#IdleActionSec=30min
#RuntimeDirectorySize=10%
#RemoveIPC=yes

But you know, after I explicitly set an action in xfce4-power-manager-settings , it worked. I think maybe this config utility shows wrong defaults.

Re: don't sleep on low battery

The real problem is that there are too many cooks in the kitchen.   Systemd tries to control this, acpid can be configured to control this, many of the Desktop Environments (Gnome, KDE, Xfce-4, Cinnamon) try to control it to.
