This 'solution' was thrown at me by Intel as well, a few weeks back.
Didn't work, or better said, my NUC was in a state that the BIOS couldn't be recovered so I couldn't even try the fix.
I didnt have video signal, the disk didn't spin up, the USB ports were dead.
I did have a solid blue front led, and I saw the Network adapter leds blinking, oh and there was a loud whirring sound coming from the fan.
The strange thing is that the NUC had committed suicide while I was away for a coupe of hours. Had to RMA it.
