I am having an intermittent issue with my BT Keyboard on startup. It will boot up and I occasionally get a message saying my system cannot detect the keyboard. It's not on every boot up but every say 1 in 3 to 5. I simply recycle the keyboard's power switch and functionality is restored. The power LED on the back isn't illuminated when I begin the procedure I am just curious on if there is an underlying issue I could be missing. Batteries are fairly new and my Keyboard preferences window says battery life is good. This issue is simply isolated to the keyboard and not the mouse. Thank you.
