ModemManager[1799]: <info> [sleep-monitor] system is resuming

Looks like this is the first indication that a wakeup has occured. The next line is Network Manager. Why we have ModemManager running has always been a curiosity, and I've seen reasoning, but I don't recall the details. Were it me, I'd kill it and try putting the laptop to sleep again and see if it stays that way. I doubt you have a modem anyway. (what I do recall is it is used by the likes of gphoto2, etc.. for some serial communications of USB. That is a vague recollection though) -- David C. Rankin, J.D.,P.E.
