I had a similar problem before, but I just reinstalled the bluetooth stack from the toshiba site and it resolved the problem.
There is no option to turn it on in the devices menu. When I try to use the connect in the AC, it says bluetooth not enabled. It used to show up in my action center but now it doesn't.
I have a toshiba satellite laptop (model # m645-s4118x) and all of a sudden my bluetooth stopped totally stopped working.
