just got a new iMac and loving it, but there is one thing that is bothering me. I typically leave my iPad on a stand next to my monitor plugged in to keep it topped off on battery. With my old Thunderbolt Display this seemed to work fine, but I am noticing that when I come home from work, my iPad only has about 70% battery from just sitting there. My guess is that the USB ports are not providing power whenever the iMac goes to sleep. Am I correct about that? Is there any way to successfully charge a device that is plugged in when you leave your iMac for awhile and it falls asleep? Is the powered poet behavior documented anywhere?
