When I'm in my house, but not next to my thunderbolt display, my magic mouse keeps trying to connect to my macbook pro. It often says "Connection Gained" and then "connection lost" within seconds. Is there a way to turn this feature off?
there's a power switch on the bottom of the mouse...
not sure what you're trying to "turn off". Do you not want this mouse to connect to your MBP? If so, go into System Preferences > Bluetooth, select the mouse, and hit the "-" button at the bottom.
Edit: Rereading, are you saying that the magic mouse is near your TBD but you've taken the laptop off somewhere else? In that event, best bet is turn the mouse off when you take the laptop away from the desk.
