Herobox n100 Disable Power LED in Linux?

Hello,

My Herobox works great. I wanted to use it as a media player connected to a projector in a bedroom with Debian 12 installed, but the power LED is too bright when not using the system. I would like to disable it in software, but it does not appear to be software controllable by default. I’m not sure if it’s not part of the device tree or if the LED is simply controlled by the “power good” signal from the PMIC.

ls /sys/class/leds/
enp1s0-0::lan input3::capslock input4::capslock input4::numlock
enp1s0-1::lan input3::numlock input4::compose input4::scrolllock
enp1s0-2::lan input3::scrolllock input4::kana phy0-led

I’ve looked into other solutions, too. I’m using a gyroscopic remote which connects using a 2.4 GHz dongle and KDE Connect. The system connects to my network using Wi-Fi. I thought I might be able to use sleep and wake the system up WoL, but that isn’t working consistently, it seems that the scripts I found only trigger once on boot, not on wake.
Using wake from USB is not ideal with the gyroscopic feature and KDE’s “sleep” option.

Before I invest dozens of hours setting up a Wi-Fi microcontroller with a Hanrun Ethernet device to connect to the Herobox’s Ethernet port to broadcast WoL magic packets, I thought I’d come here for advice.

I figure, the power consumption is low enough that I can leave it on all the time, but I’d prefer to not cut the trace or desolder the LED on the board. Is there a software solution?

If the LED is not controllable, sorry man but desoldering is your only option.
There might be a way by sending UEFI BIOS requests (you can do it on the rpi) or maybe the BIOS itself has the option to disable the LED (probably not).
You know… there is always the option of sticking a bit of tape over the LED… just sayin’

I am sorry but we cant help on this, lets see if any people more specialized could help.
