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:
Sleep by manually clicking the Apple logo in the upper left corner of the screen -> 'Sleep':
Sleep by manually pressing control + eject, and the press 'Sleep':
Sleep by turning on the application called 'PleaseSleep' based on the settings from 'Energy Saver':
If I disable 'PleaseSleep' and only depend on the non-working 'Energy Saver', nothing happens.

Looking forward to your replies! Thanks in advance!
