Does anyone know how I can change the power profile on TLP from “balanced” to “low-power” so that it will survive reboot?

    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
