I have a 13" late 2013 rMBP running Mavericks. When I'm on battery I've set the display to turn off after 2 minutes for obvious power saving reasons. But it also disables Wifi and I can't tell if it sleeps or if it's just the display, since it's completely quiet all the time and it wakes instantly (tough problems, i know ). Is it supposed to be this way? Does it actually sleep or does it just disable wifi and either way, is it a way to prevent this? Because even on battery I still want to be alerted by Skype and continue using torrent-programs. Thanks in advance!
