Does anyone know how I can change the power profile on TLP from “balanced” to “low-power” so that it will survive reboot?
There is an information in the
/etc/tlp.conffile:# 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-powerSo, it depends if your distro uses
power-profiles-daemonor 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_profilein 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?Do you want
low-powersetting only on a battery?Create, for example,
/etc/tlp.d/99-custom.conffile, with content:PLATFORM_PROFILE_ON_BAT=low-powerReload the settings:
tlp startAnd make sure the
tlpservice is enabled.Do you want low-power setting only on a battery?
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:
CPU_SCALING_GOVERNOR_ON_AC=performance CPU_SCALING_GOVERNOR_ON_BAT=powersave CPU_MIN_PERF_ON_AC=0 CPU_MAX_PERF_ON_AC=100 CPU_MIN_PERF_ON_BAT=0 CPU_MAX_PERF_ON_BAT=30 CPU_BOOST_ON_AC=1 CPU_BOOST_ON_BAT=0 CPU_HWP_DYN_BOOST_ON_AC=1 CPU_HWP_DYN_BOOST_ON_BAT=0 SCHED_POWERSAVE_ON_AC=0 SCHED_POWERSAVE_ON_BAT=1 USB_EXCLUDE_WWAN=1
