    Hello,
    I have a MacBook (13-inch, Mid 2009) running Mac OS X Snow Leopard 10.6.3,
    and it has been installed with the latest software updates possible.
    (The latest update is the 'Security Update 2010-003')

    Previously I was using Mac OS X Leopard 10.5 on my MacBook,
    and I can vaguely remember the timed computer sleep through Energy Saver would work.
    That is, when the counter's time matches the amount of time I specified (e.g. 10 minutes), the computer enters sleep mode and displays a pulsing power light.

    After upgrading to Snow Leopard I can barely remember the scheduled computer sleep will work as I don't really notice how it sleeps / I will shut down my MacBook before I go to bed.

    ==========

    However, last night I was really tired and slept in front of my MacBook unconsciously.
    When I woke up, I found that my MacBook didn't display a pulsing power light but a continuously-growing power light.
    I tapped the trackpad and the display turned on, so I knew that my MacBook didn't go to sleep a whole night.
    What that means is that the Sleep Timer (through 'Energy Saver' in System Preferences) won't work.

    But the timed display sleep DOES work.

    ==========

    After spending a whole day Googling,
    I found that there are plenty of people suffering the same problem as me, although their Macs and OSs vary.
    I also found an official support page from Apple concerning the related issue:

    Mac OS X: Why your Mac might not sleep or stay in sleep mode
    http://support.apple.com/kb/HT1776

    I tried the following methods but still can't resolve the problem:
    - boot my MacBook in safe mode
    - use the 'Disk Utility' to repair Disk Permissions through booting my MacBook from the Mac OS X Snow Leopard Installation DVD
    - reset NVRAM (Intel-based) (as PRAM is used by PowerPC-based Macs)
    - reset SMC (System Management Controller)


    NONE of the above-mentioned methods can resolve the problem.
    Althought I am sure that the Spotlight isn't indexing the hard drive, and I just start my computer and do nothing and wait for the scheduled computer sleep, the scheduled computer sleep just won't work.

    In this forum, I saw someone suggest installing an application called PleaseSleep:
    http://www.dragonone.com/products/macosx/pleasesleep/
    It works.
    But I really want to find out what caused this problem as this is a function shipped with Mac which is expected to work normally.
    What's more, Apple is claiming to be a green Apple, right?

    Here's the log taken from 'Console':

    Sleep by closing the lid of my MacBook:

    If I disable 'PleaseSleep' and only depend on the non-working 'Energy Saver', nothing happens.

    Looking forward to your replies! Thanks in advance! :)

    I have the same problem. It seems that under either battery or power, it will turn the screen off, but it will not put the computer to sleep. Closing the lid, does have the desired result. I have tried changing and saving the settings, rebooting the computer, but dont really know what else to do. Suggestions?
