There is an information in the /etc/tlp.conf file:
# Select platform profile:
# performance, balanced, low-power.
# Controls system operating characteristics around power/performance levels,
# thermal and fan speed. Values are given in order of increasing power saving.
# Note: check the output of tlp-stat -p to determine availability on your
# hardware and additional profiles such as: balanced-performance, quiet, cool.
# Default:
# !!!!!!!! Warning !!!!!!!!!
# When use power-profiles-daemon, please use below items in
# /var/lib/power-profiles-daemon/state.ini
# 1) "balanced" is default mode
# 2) "power-saver" mode means "low-power" in ppd
# 3) "performance" mode
# !!!!!!!!!!!!!!!!!!!!!!!!!!
#PLATFORM_PROFILE_ON_AC=performance
#PLATFORM_PROFILE_ON_BAT=low-power
So, it depends if your distro uses power-profiles-daemon or if your desktop environment controls power profiles.
I’m on Linux Mint Cinnamon 21.2; power-profiles-daemon does not seem to be installed on my system 🤔.
Typing cat /sys/firmware/acpi/platform_profile in the terminal comes up as “low-power”, which is what I switched it to from “balanced” by hitting Fn+l. How do I get this setting to survive reboot? Do I uncomment “#PLATFORM_PROFILE_ON_BAT=low-power” or is there another way?
Yes, that’s what I’m aiming for. I’ve got a thinkpad x1 carbon 10th gen which is known for its not-so-great battery life, and so I’m trying to use the low-power setting for battery-only to see if that helps. If that doesn’t work I might try auto-cpufreq (do you know anything about that?) In any event, thanks very much for your response, I’ll create the .conf file and see if it works. 🙂👍

TLP can also control CPU clock.
I’m using these settings on my trusty X260:
