Comment 66 for bug 1153488

I'm getting this error on Mint 17.2 w/kernel 3.19.0-26 too. My bluetooth mouse seems to be fine (no battery registering), but my keyboard is showing as a 2nd laptop battery. It keeps disconnecting my keyboard so I have to press a button to wake it back up. Guessing it may be putting it to sleep because of an idle setting somewhere?
