I have a Lenovo Legion 5 Ryzen 7 4800H cpu with AMD graphics and an Nvidia GTX 1650 Ti. Everything works great except for some minor annoyances that I am trying to solve, like backlight restore after reboot. This one is already covered in the Arch wiki. (I just removed quiet from kernel parameters.)
I am looking for help on the FnLock LED in the Esc key. I have noticed that the FnLock functionnality activated with Fn-Esc keys does not change the LED status. The media keys work correctly it is just the LED wich is not working.
What I have tested so far :
* Manually activating FnLock using
echo 0 | sudo tee "/sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/fn_lock"The LED is on and the media keys are activated.
* Deactivating and activating using Fn-Esc keys, works but the LED stays on in all cases.
* Using :
echo 1 | sudo tee "/sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/fn_lock"The LED is off and FnLock is deactivated.
A similar issue on a thinkpad laptop just got fixed in the module thinkpad_acpi. This laptop uses the ideapad_laptop module.

No one else having the same issue?
Should I report it somewhere like https://bugs.archlinux.org/ or upstream?
Edit:
This is the bug report upstream https://bugzilla.kernel.org/show_bug.cgi?id=212671

I also use Lenovo Legion 5 and have the same problem.

Same issue.

The Fn+Esc key combination sends an unhandled WMI event, so you can try to patch the kernel.
