[Bug 1229999] New: High idle power usage on Lenovo Slim 7 16" AMD
https://bugzilla.suse.com/show_bug.cgi?id=1229999 Bug ID: 1229999 Summary: High idle power usage on Lenovo Slim 7 16" AMD Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Other Assignee: screening-team-bugs@suse.de Reporter: variable_valuables761@simplelogin.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Tumbleweed seems to have unusually high power consumption when idle. I tested on KDE (Krypton live usb) with nothing open except Konsole running powertop, and compared with Fedora Rawhide live usb. My machine is a Lenovo Slim 7 16" AMD (16ARH7, 82UX0001US). Outputs from powertop attached (Overview & Device stats): ~25W on Krypton vs ~14W on Rawhide How should we diagnose what the issue could be? (Note the ongoing issue with Pipewire/libcamera webcam power usage has just been fixed in libcamera, which has not been released yet. Disabling the webcam as a workaround only drops power usage by a few watts on my system.) -- You are receiving this mail because: You are on the CC list for the bug.

The idle CPU/GPU temperatures and fan noise both seem noticeably lower in Windows though compared to both tested distros. -- You are receiving this mail because: You are on the CC list for the bug.

Have you tried adjusting via powertop --auto ?
Hi Takashi I remember having one bug report related to this topic. I was showing comparison between clean ubuntu and clean tumbleweed intall with ubuntu using 3-4 times less power in idle state. I think I was not convincing enough but now it is another person with another hardware stating the same. I tried to switch from power-profiles-daemon to TLP and results are very promising. I will add them below. Still a strange thing is that ubuntu uses PPD instead of TLP anyway... Hi , I did some testing , my setup is: • XP9700 with 4k display , dual NVME • brightness set to 20% • wifi on and connected, BT on and connected to mouse • OpenSuse Tumbleweed with latest updates and 6.7.5 kernel • KDE plasma 5.27.10 on Wayland and a number of autostart apps • I did restart before each test both for PowerProfilesDaemon (PPD) and TLP. PPD : in power-saving mode using KDE was a pain I experienced 1-2 seconds gui freezes, plasma animation stutters and I can literately feel system was extremely slow , still power consumption/discharge rate was huge on performance mode I the experience was OK but with a lot of heat forcing the fan to go crazy or if I forced thermal mode to quiet my laptop would burn my hands. TLP: all works smooth, no option to change modes in KDE plasma integration on power connect/disconnect events but it seams TLP is clever enough so no manual settings are required. Measurements: See the graph where I marked PPD with yellow and TLP with green. Conclusions : I changed to PPD some time ago when I discovered Alex’s Dell-power-manager app that supported it well, then I discovered PPD had nice integration with KDE plasma that allowed me (in gui) to set profile changes to power-saving when AC was disconnected. Now after comparing the data and the experiences I am reverting back to TLP and I recommend the same. See the graph attached. -- You are receiving this mail because: You are on the CC list for the bug.

Fedora Rawhide got as low as 13.7W, but Krypton only got as low as 24.0W. The CPU in this laptop is an AMD Ryzen 7 6800HS Creator Edition, and the dedicated GPU is an Nvidia RTX 3050 Mobile (but the built-in display is connected to the AMD integrated GPU). -- You are receiving this mail because: You are on the CC list for the bug.

I'm surprised it didn't lower power usage. If there's anything else I can test let me know. -- You are receiving this mail because: You are on the CC list for the bug.

So it seems so far that only recent Fedora versions have lower power draw (~14W). Does this maybe have any relevant info? https://fedoraproject.org/wiki/Changes/TunedAsTheDefaultPowerProfileManageme... (Fedora had less power draw even when replacing tuned with p-p-d or tlp though, in my previously mentioned tests) -- You are receiving this mail because: You are on the CC list for the bug.
