I've done a bit of digging...

This is the same device (it appears) as the Dell G5 5500, Issue#88, only this machine only has one LED on the front panel (perhaps by default - I'm not sure if you can plug more in).

The following worked for me (using elc_ng.py):

#!/usr/bin/python3

from elc_ng import ELC, ColorCommand

elc = ELC(0x187c, 0x0550)

with elc:
	elc.execute(ColorCommand([1], 0, 255, 0))

I haven't spent much time digging into this yet, however. I tried writing a new DellG5_5000.ini, but I don't know enough about akbl to make this work for me (yet)...

I should add that I tried ColorCommand([0]... through ColorCommand([16]... but only [1] worked for me. The LED on the power button (the only other light on the front panel) didn't twitch, so I think that this G5 5000 only has the [1]...

Hello @cpknight ,

Does the block testing window works?
