https://bugzilla.kernel.org/show_bug.cgi?id=216347 Bug ID: 216347 Summary: ACPI power profile keeps switching to "low-power" on ThinkPad T14 Gen1 (AMD) Product: Drivers Version: 2.5 Kernel Version: 5.19 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Platform_x86 Assignee: drivers_platform_x86@xxxxxxxxxxxxxxxxxxxx Reporter: madcatx@xxxxxxxx Regression: No Hi, I recently discovered this annoying behavior. 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_profile" I observe the power profile always dropping to "low-power" a few seconds after 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?
