LED devices are easy to find because they available are in the /sys/class/leds/ directory. So I think it's a good thing to define LED names somewhere. J Luke missed this LED from /sys/class/leds/, that's where the idea came from. The scrollock, numlock, capslock and kbd_backlight LEDs are already exported. https://github.com/tomsom/yoga-linux/issues/58#issuecomment-2029926094 Best regards, Gergo
