Lose connection with wireless keyboard/ mouse
I'm using 10.9.1 and continually losing the connection with the wireless keyboard or the bluetooth mouse. I've changed the batteries. I've gone to System Preferences, clicked on keyboard and used the assistant to re-connect. But why is this happening at least every 3 days. First the keyboard. Then the mouse.
