I have upgraded to Ubuntu 22.04d OEM 6.5 kernel. Also installed @Mario_Limonciello PPD PPA.
The upgrade broke the OEM c kernel notification & grub edit script which insisted on sticking with OEM 6.1 rather than 6.5 kernels, but I got through that.
With just these two changes, plus powertop --autotune my power consumption has dropped quite a bit, now baseline in the 4-5 W range. Web surfing has not exceeded 7W so far.
After several hours of use, powertop reports 94% in C3 overall.
I also tried this approach, and it works fine. I had to stop Dropbox and Mattermost to get down to 5W, but 5W with gnome-power-statistics as only running app with WiFi ON and Bluetooth off on brightness level 2 (if 1 is the lowest) works.
Governor “Balanced” works best, full performance if needed and low power consumption otherwise. No need to switch the governor that you use when on power or on battery.
I was running sudo powertop --calibrate once (takes a few minutes, don’t touch your laptop while it is running). And I added this service:
Also positive feedback from here, @Mario_Limonciello. Installing your linked ppd package on Fedora 39 brings down my power consumption from ~9W on idle (medium screen brightness, wifi on, nothing running) to consistently ~4.3W on power-save and around 5.3W on balanced or performance modes.
What branch or commit did you build from specifically? I want to make a PKGBUILD for this for arch (haven’t ever submitted anything to the AUR before, but I imagine there are enough arch/amd framework 13 users to make this worth it)
Thanks for this, you and everyone above. I’ve been trying to follow this discussion as best as I can.
While TLP seems to show more promise than initially thought, the current recommendation seems to be to use PPD. Now that recommendation has evolved into using Mario’s AMD patches for PPD as well. Am I following this correctly? Also, is powertop --auto-tune also suggested on top of PPD?
I need to perform more stringent monitoring, but powertop puts my idle baseline power around 6.5W with 50% brightness on the FW13 7640u running Arch 6.6.8.
I made a note of my interpretation for Arch users in the Arch Wiki Framework stub. Please feel free to edit/correct.
