I have Thinkpad x250 with freeBSD 13.1 RC4 with most of tweaks I could find online and in man pages enabled but I cannot get my power consuption below 5.5W even with all those tweaks and I am using BSPWM for comparison MS windows 10 uses 7 watt with all bloat running and UBUNTU 22.04 GNOME 42 uses 2.5 out of the box
any Ideas how could I get more power savings
here is my confs
/etc/sysctl.conf
/etc/rc.conf
/boot/loader.conf
/etc/rc.local
Thanks
