cannot disable power LED (model 2 rev b) #148

Raspberry Pi Model B Rev 2

cat /etc/debian_version 
10.7

I just installed the newest raspbian on my pi and I am trying to disable the power LED. I think this used to work like 2 year ago.

If I select the option in raspi-config I get The LED behaviour cannot be changed on this model of Raspberry Pi followed by There was an error running option S8 Power LED

raspi-config checks /sys/class/leds/led0/trigger https://github.com/RPi-Distro/raspi-config/blob/master/raspi-config#L1134 and it seems on my model the path is different:

pi@raspberrypi:~ $ cat /sys/class/leds/default-on/trigger

The LED behaviour cannot be changed on this model of Raspberry Pi

That's correct. As it says at https://gpiozero.readthedocs.io/en/stable/recipes_advanced.html#controlling-the-pi-s-own-leds "On the original Pi 1 (model A or B), the activity LED can be controlled with GPIO16 (after disabling its trigger as above) but the power LED is hard-wired on."
