SO, from running sudo powertop I have
18.3 W 1,0 pkts/s Network interface: enp2s0 (r8169)
9.07 W 21,9% CPU misc
5.23 W 0,0 pkts/s Network interface: wlan0 (iwlwifi)
...
The above from a system consumin ~33W.
I’ve already tried the followinf config:
{ config, pkgs, ... }: {
services = {
acpid.enable = true;
acpid.handlers.ac-power = {
action = ''
vals=($1) # space separated string to array of multiple values
case ''${vals[3]} in
00000000) # unplugged
#${pkgs.systemd}/bin/systemctl stop 'beesd@*' 'borgbackup-job-*' boinc
${pkgs.systemd}/bin/systemctl start auto-cpufreq
echo 2 > /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy # silent fans

rfkill block 1

Also in my experience virtual network link like the one created by Virtualbox consume a disproportionate amount of power on idle.
How do I reduce the power consumption of network links?
