I was installing a couple of bitcoin-/lightning nodes on old laptops lately to play around and test stuff. One of the first things todo is always to disable the slepp/suspend/hibernate modes, which is basically just one command like

$ sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

But what I missed twice now was to also ignore the LidSwitch, which is something you don't really notice until you look at your cpu-load. So, if you're like me and run nodes like umbrel or start9 (otherwise you probably know what you'r doing) on laptops, check ur logind.conf and uncomment/edit the HandleLidSwitch entries

$ sudo nano /etc/systemd/logind.conf [Login] HandleLidSwitch=ignore HandleLidSwitchExternalPower=ignore HandleLidSwitchDocked=ignore

My cpu-load went down from ~80+% to ~30% just doing that, which not only consumes less energy, but also gives me room to install more shit I don't actually need.

Just thought I'd tell ya.
