Every now and again I find my laptop merrily chugging away in the morning, but had left it off the night before.  Sometimes I can uncover the culprit after digging around in the event logs, but sometimes not.  Just like a sudden crash,  Windows does not seem to know exactly what event occurred to cause it to come out of hibernation/Off.  Is it possible to determine ?  Or, at least have a pop-up window that shows SOME information, like time slept, time resumed, event?, etc.  At least I'd have some idea of when it happened.  One culprit was the Media Center schedule updater (This is a Vista Premium Laptop).  I have looked into the Vista Task Scheduler, but it it a bit more complex than XP's and I am hesitant to tamper with some of the settings as I'm not sure exactly the ramifications.  But, I would have more confidence in my selections given more information.

Can anyone offer a comment, opinion, or help?
