I know the NUC I had had it's ethernet port put PERMANENTLY to sleep. There was, eventually, a Windows program which hacked the device to take it out of sleep.

I know the NUC I had had it's ethernet port put PERMANENTLY to sleep. There was, eventually, a Windows program which hacked the device to take it out of sleep. But I had no Windows OS on it. Before I got around to installing enough Windows, the NUC died for other reasons :-(
