I set the keyboard as 'favorite' in system preferences. One forum said to trash certain files, but I couldn't find those files so I don't know if that could help. Every couple of minutes the 'connection lost' will appear on the screen, and then 'connected' will sometimes appear a couple seconds later. And then it will say 'connection lost' again but it won't reconnect. I have it paired with my MBP, which is connected to my flat screen T.V. and don't have anything that I think could be interfering with the signal. I have the bluetooth off on my phone and even keep it away from my keyboard and computer. Any help is greatly appreciated.
