beroot Posted October 25, 2019 Share 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) 0 Quote Link to comment Share on other sites More sharing options...

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. 0 Quote Link to comment Share on other sites More sharing options...
beroot Posted October 30, 2019 Author Share 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. 0 Quote Link to comment Share on other sites More sharing options...

For the USB LED, no way to turn it off, so, you can either put a drop of black paint on it, or a black tape, or brake the LED itself ... 0 Quote Link to comment Share on other sites More sharing options...

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?

You could use rc.local for example to turn off the leds once the boot has been finished. 1 Quote Link to comment Share on other sites More sharing options...
