my sleep seems to have gotten really long. I just closed the lid and the light was on for 30 seconds before showing it was asleep. I've been plugging it into an external display quite a bit lately. could this be a cause? I've uninstalled all my printers so I don't think it can be a printer issue because there is nothing under printers now. ive also tried: sudo pmset -a hibernatemode 0 still takes 20 seconds atleast.
