Hi
I just built a NAS server with at ASROCK J3455-itx
everything is working perfectly except hibernation.
I think i figured out it has something to with the computer trying to read the LED brightness. But it cant and wakes up again.
i found this in scemd.log:

As you can see it keeps on waking up right away and go to hibernate 10min after.
Can someone tell me how i turn off the brightness reading ?
