Description Iyán M. V. 2023-01-22 18:05:47 UTC 
SUMMARY
After upgrading to Plasma 5.26.90 I cannot change the Power profile anymore. Some events can still trigger a change (e.g. connecting laptop to AC after setting , but the moment the profile is manually changed, it is not possible to change it again. This issue is not just a "visual" bug in the battery and brightness panel. Trying to change the power profile with keyboard shortcuts (Fn + H, Fn + M, Fn + L) or writing to /sys/firmware/acpi/platform_profile is also blocked somehow by Plasma.

STEPS TO REPRODUCE
1. Try to change power profile

OBSERVED RESULT
It doesn't work anymore. Here is a video showing the issue.

ADDITIONAL INFORMATION
I just saw that there has been also a recent kernel upgrade doing some changes to thinkpad_acpi. Unfortunately, I upgraded both Plasma and linux at the same time. I will try old kernels to double check that this is indeed a Plasma bug and not a kernel bug.

Maybe this was a one time weird event? I cannot replicate anymore neither with latest kernel version nor with previous versions. I will keep the report open for a few more days, if I don't observe the issue anymore I will close it.
Comment 2 Iyán M. V. 2023-01-23 22:10:42 UTC 
Before I forgot to reboot after upgrading kernel again. This is clearly an issue that started with linux 6.1.7, not Plasma's fault.
