I recently got the Apple bluetooth keyboard and mouse and I'm using it with my 12" PowerBook. I was wondering about the sleep habits of the two. I know there are on/off buttons to save battery. I was wondering if the mouse and/or keyboard automatically go to sleep if they are not used for a period of time. I think they might because if I come to my computer after being away for awhile, the laser on the mouse is completely off. I'm assuming it shuts off after some time. Can anyone else verify this?
