I use an udev script to toggle between "low-power" and "performance" ACPI power profiles based on whether = the laptop is plugged into a wall. By cat'ing "/sys/firmware/acpi/platform_prof= ile" I observe the power profile always dropping to "low-power" a few seconds af= ter I manually change it to something else. The machine has a 4750U Ryzen chip and the latest 1.41 firmware (DMI: LENOVO 20UDS02D00/20UDS02D00, BIOS R1BET72W(1.41 )). I run the latest 5.19 kernel. I tried to toggle between S3 and S2idle sleep modes but that doesn't seem to make any difference. Is there anything I can do to help track this down?
