Hey @Moors7 and @billybonks, I am currently experiencing the same issue. In my situation the pin D7 led is lit but the status led is not. Similar to this thread.
I reached this state by connecting VIN to a 5V power supply (no regulator in between). I have disconnected the Photon from everything and now if I plug the Photon into a USB port on my laptop I just get the pin D7 light, no status light (and shows as not connected in Dashboard).
