beroot Posted October 25, 2019 Posted October 25, 2019 Hi all together, on a Raspberry Pi 3b and 3b+ as well as on a Odroid-C2 I know how to switch off the blinking LEDs s or Power LEDs. Does anybody know how I can switch off or dim that extremely bright red power LED from the OrangePi3? I tried a script snippet like this: echo none > /sys/class/leds/orangepi\:red:\power/trigger But it wont work. Has anybody a helpful hint for an unpatient contemporary? Thanks for help :o)

You need to add : echo 0 > /sys/class/leds/orangepi\:red\:power/brightness Note there is also another red LED near the USB ports which glows when some USB devices are found, this one can not be turned off, you need to place black tape on it.
beroot Posted October 30, 2019 Author Posted October 30, 2019 Hello, sorry for late response and thank you for your answer. It works. The Power LED can only be turned off. For an inserted USB Stick I really need a solution. Thanks for help.

I turned off the red LED with this method and everything will reset the next time I start. And the red LED is lit. Why can this be? "Orange Pi 3 - Armbian 20.05.2 Buster Current 5.4.43"

Why can this be? "Orange Pi 3 - Armbian 20.05.2 Buster Current 5.4.43" Because it is not permanent. You could use rc.local for example to turn off the leds once the boot has been finished. 1
