I'm having an issue with my MBP not going to sleep with the lid open. I have had many other Macs and have never has trouble with them going to sleep. I have set mine for the display to turn off after 10 minutes and for the computer to sleep after 15 min. I'd like to use as little power as possible and I'd last the laptop to last a long time but if I forget to close the lid, I can guarantee that it will not go to sleep. I usually put on a movie with quicktime (perian codecs) before bed and I'd expect it to turn off 15 minutes after the movie, is that what it should do? I have no other third-party apps running in the background unless the weather channel widget would cause this. In Windows 7 I have zero issues with this, it'll sleep after 15 minutes no problem, anybody else having this issue?
