Hi there. I'm a total novice and just disconnected my computer as had to move to another room. I've made a note of everything and its reconnected just fine. The screen is showing a light and when I plug into the back of the hub its also flashing with a green light. I'm not sure what else to do but when I try to power button on the front of the unit absolutely no response at all? Does anyone know of a secret switch I'm missing, process, etc??? Need desperate help as have like 3 proposals to finish today :)
