    I have a Mid 2010 edition Macbook Pro running Lion and I recently noticed that it will not sleep if I close the lid or select sleep from the Apple icon if it is connected to the power adapter but it sleeps fine (using the sleep light as an indicator) while on battery power or I put it asleep on battery power and then reconnect the power adapter. Also, at times, when I open the lid (never having gone to sleep), the screen comes on and then turns off after 5-10 seconds. Any ideas?

    Running on AC power or battery shouldn't affect the ability to sleep, unless you have different settings in the Energy Saver profiles.

    I got the exact same issue and just noticed this.

    If I unplug power adapter, it goes to sleep. I checked the settings, even rebooted the mac - still same issue.
    Running latest Lion release.
    Only my is a late 09 macbook.

    Will try a disk repair&permissions.

    Fixed..

    Go into your prefs - turn on all sharing options - reboot - come back and disable them.

    Close your lid - mac should be sleeping now.

    No idea why this was an issue but it fixed it for me after I read about it online as some people suggested. good luck

    For anyone having the same problem, it seems to be an issue with Internet sharing. So turn that off, and you should be golden :) .
