Interestingly it fails in the step |

Also check if there is another module that provides platform profile support, e.g. get the output of sudo dmesg | grep platform
sudo dmesg | grep profile |

The above-mentioned failures continue to occur with the latest commit, 2e47eaf. Can you please suggest any troubleshooting ideas or tricks that might reveal what is going on here? |

We have to find out why there is already a platform profile support loaded. In the meantime, get the newest code and load it with sudo make reloadmodule_disableplatformprofile or set the kernel parameter legion_laptop.enable_platformprofile=0. This skips loading the platform profile but loads all other features. So you can do everything except reading and writing the power mode from software. What is the output of ? cat /sys/firmware/acpi/platform_profile_choices

Yes, you should now be able to load the module without forcing it but still with disabling platform profile, i.e. with I guess that the best solution would be to manage powermode/platform_profile with legion_laptop and disable it ideapad_laptop. You can maybe try to disable it by setting the kernel parameter allow_v4_dytc in the ideapad_laptop: https://github.com/torvalds/linux/blob/91aa6c412d7f85e48aead7b00a7d9e91f5cf5863/drivers/platform/x86/ideapad-laptop.c#L135 If this does not work, I could export the power mode as another sysfs attribute that is used be the GUI. If you just use ideapad_laptop without legion_laptop, does the platform_profile file changes if you change it with Fn+Q? |

Not sure if this is expected behaviour or not, so I'll describe it before showing several lengthy dmesg spews: Doing [Fri Aug 18 00:07:23 2023] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PC00.LPCB.EC0._Q44.WM00], AE_NOT_FOUND (20230331/psargs-330)

The driver was intended for Legion laptops and not Yoga laptops. Your ACPI dissassembly (zip files) shows that the ACPI firmware and the WMI interface is different. However, the output of I am confident we can make it work after solving the problems with ideapad_laptop. I have think to about it a bit. In the meantime, you try finding the reason for run |

Speaking purely for myself, the only thing I really need is configurable fan-control functionality. Getting it to a point where it takes effect automatically and reliably at boot-time is icing on the cake. The rest of the driver's functionality are quite nice-to-haves, but not critical. The only Fn keys I really need are the volume/mute controls, I don't really care about backlight controls, and I don't frequently need to toggle power-modes - this laptop isn't used for gaming. Mainly, I want to ensure I'm not blowing out internal components with things like Thanks very much for your efforts thus far in getting the driver to load and manage the fans! |

Any guidance on how to get the
