MacBook - MacBook will not sleep!

My MacBook is almost 1 year old and about a month ago it decided not to sleep anymore. As you can imagine it is annoying to have to shutdown every time i put the computer away if I don't want the battery to die. I've detailed the problem and things I have tried with no success:

Symptoms:
Computer doesn't appear to go to sleep when using Apple Menu - Sleep, by closing the lid, or as stipulated by the Energy Saving Preferences.

The screen does dim and go to sleep as it is supposed to, but the computer battery dies as if it weren't sleeping. Also the light on the front does not pulse.

Extra Information:
I have nothing connected to the computer via USB, Fire, or Bluetooth. I am running the latest OSX 10.5.5 and have the latest firmware update.

Attempted Solutions:
I have uninstalled all HP software as I read that it may have adverse effects.

I have verified and repaired disc permissions using disc utility.

I have turned the computer off, removed the battery, and performed the 5 second power thing.

Does this sound like a hardware problem? Or a software problem?
Help appreciated! Thanks!

Have you tried pressing and holding Alt(option) + R and Command (apple) + P while powering it on until it chimes 3 times? This should reset the pram.

Also go to Systems Preferences>Energy Saver and make sure the box is selected putting the computer to sleep.
