Wireless or Bluetooth keyboard keeps disconnecting
I work on a Macbook Pro, and have an apple wireless keyboard and magic trackpad so that I can sit further back from a large screen that is plugged into the Macbook. The track pad oddly always stays connected. I get an image of a keyboard and the words Connection Lost. This happens 10 - 12 times a day, last 3-5 seconds, and I lean forward to use the keyboard on the macbook. It always comes back, but the problem is that it always disconnects!
Batteries are fine and I have changed them several times over teh last few months. I have deleted the device from Bluetooth Preference, re installed, made favourite and no bananas. I have turned off wifi on the Macbook, so not a factor. I believe this started after upgrading to Mountain Lion, but can't remember for sure. I don't sit in a microwave, have 2.4 mghtz phones or anything similar. I haven't reset the PRAM, and what ever it's now called with the Intel chip. Should I?
Any advice would be greatly appreciated, thanks.
