MacBook not sleeping on its own when inactive
I would like to ask everyone to target on the "MacBook not sleeping after being inactive" issue, please do not post similar problems, such as inability to wake from sleep, waking up with lid closed and so on...
In my case, I'm on a Santa Rosa 2GHz MacBook (bought it a month ago) and I recently noticed that it won't sleep on its own, when left inactive (no user activity) for a time period longer that the one set via Energy Saver Preference under System Preferences. There are no strange processes taking up PCU time, no kernel extensions and so on. I have already tried most of the tricks I am reading of around the net (SMC reset, erasing certain preferences), but with no luck. As I said above, it sleeps just fine when closing the lid, or using other manual procedures.
I would like to hear from anyone who've face the SAME problem and successfully managed to overcome it. Thank you.
MacBook (Santa Rosa) @ 2Ghz, Mac OS X (10.5.2)
