Passport ultra stops

I had an outside computer tech monitor my system. I no longer use him. He told me last month that my passport ultra had stopped. He restarted. I need to know how to see if working and, if not, how to start. He has not returned any of my emails concerning this and I need your help. PS: I’m not exactly an expert on computers. Any help would be appreciated.

Hi,

Look at the front of the Passport. Is the light on or blinking? If yes the Passport is working, but you need to check instructions to learn if it is doing anything useful.
