The screen no longer shows his eye, and even if I touch the screen, nothing happens. Does this mean that the server was finally shut down?
Unplug, wait for 5 hours, plug back in. Sometimes he gets into a funk.
Thanks. I will try it.
I believe you can also hold down the power button on the back of his head until he shuts down. Release the button, and then press it again to reboot him.
Also if Jibo is sitting there with the red light on, then he is in Recovery Mode. For that there are instructions here for that (but basically you flip open the back panel on his head and hit the top small button).
