I have a lenovo Y510p, and have installed Ubuntu 16.04 on it. My built-in bluetooth in my laptop abruptly shuts down and my music switches to my laptop speakers. I cannot switch it on again using the GUI. The command sudo service bluetooth restart does not help either.

It usually helps if I restart, but that's quite annoying.

I have this output from the command sudo service bluetooth status .
