So as the title says when I disable cpu turbo boost using echo 'w /sys/devices/system/cpu/cpufreq/boost - - - - 0' > /etc/tmpfiles.d/disable-cpu-boost.conf to disable it permanently my power slider stops working. I already tried changing power profile using “powerprofilesctl set” command and it still won’t work. Enabling cpu boost back fixes the issue. Anyway to leave boost off but still be able to change my power profiles since I sometimes use my laptop on battery and would love to be able to change to power-saver which lowers the core clock even lower then balanced or performance? Cpu is a 7640hs which has a base clock of 4.3ghz and boosts to 5ghz. Using power-saver profile the max clock is around 2.4ghz. Thanks!
Welcome to the forum 
Not sure why you want to disable the turbo boost because as I understand that will only kick in on heavy workload. See also this link:
Cpu going to 90-100 C when gaming and even worse when compiling shaders. I already cleaned it and temps didn’t change much cause it’s just a crappy cooler design. Either way with turbo disabled the performance in games doesn’t change much since the base clock is 4.3ghz and it doesn’t seem to limit my rtx 4060 but it does however lower temps to around 60-70 C.
Have you checked in your Bios settings to see if there is a setting for disabling CPU boost?
Also, as something to try, have you experimented with cpupower for CPU frequency scaling?
I think using cpupower, you would need to completely disable/mask power-profiles-daemon.service
can you report
inxi -Fza
cpupower frequency-info
sudo lscpu -aeI’ll get back to you when I get home.
