I've tried my 5560 workstation and it refuses to recognize any power supply as being adequate other than the original.  I've tried a 250w HP thunderbolt dock, a 200w Caldigit dock, and an Anker 135w dock.  Any of these should have plenty of power but I always get the message on boot that the power supply is not enough and warning icon on the power status once its booted.  Does anyone know how to convince it I've provided it with enough power?  

Thanks
