I have an early 2011 MBP 15". Everytime I use the hotkey to sleep or do it from the apple menu it takes 30 seconds for it to sleep. This is with no programs running, no sharing prefs enabled, and nothing out of the usual going on in activity monitor. I reset the PRAM and that didn't do anything. Could this be a disk issue? I do have a self installed drives, a SSD running lion. Any ideas on a quick fix?
