I have wasted quite some time getting remote start up of a NUC5CPYH by sending a magic packet operational, but it does work.
The thing that stumped me was a setting in windows.
Control Panel\All Control Panel Items\Power Options\System Settings
Uncheck the recommended setting : Turn on fast startup
It will then start from a turned off state when you send a magic packet ( although the little lights at the ethernet socket don't glow in the turned off state until it reboots)
