Still having sleep issues...

I thought the Firmware had fixed the sleep issues that all of the sudden began to plague my MBP. It did not.

For some reason, when I close the display to my MBP, it does not enter sleep mode. It turns off the backlight, but will remain on. I have to tell it to go to sleep before I close the display.

The weird thing is, I was not having this problem until I read about it on this forum. And, literally, that same day, mine started doing it. Probably a coincidence, but weird nonetheless.

If anyone knows anything about this issue, advice would be great. Or, if you are having similar issues, tell us about it.

Have you tried resetting PRAM, plugged out the battery and held down the power button for 5-10 seconds?

Reinstalled Mac OS X?

I have not tried either of these yet. But, I will not be re-installing OS X. If that is the only way to fix the problem, then I can continue telling my MBP to go to sleep before closing the display.
