Macbook Pro won't sleep while charging.

[TeraVan]

My 13" i5 MacBook Pro 10.7.1 won't sleep when charging; my machine sleeps just fine, so long as it's not plugged into A/C power.. If I open the lid, my screen is allready illuminated (because it's not been asleep). Any advice? I have already tried:

-System Preferences > Energy Saver > Power Adapter > unchecked all the boxes,
-reset SMC and PRAM,
-repaired permissions,
-unchecked "wake for network access" in Preferences > Energy Saver > Power Adapter
-turned off internet sharing in System Preferences.
-searched forums for solutions, but no luck.

Nothing above solved the problem. Maybe you can help me...

Thanks a lot.

Are you sure you correctly reset the SMC and the PRAM? Usually this takes care of things.

Check to make sure you don't have any applications open that are blocking it from going to sleep (and if you can, test this without having anything running at all).

Go to terminal and type in

sudo pmset -g

type your password, then paste the output in your response.

Yes, I am sure that I reset the SMC and the PRAM correctly. I heard startup sound two times, as it says here. And the LED on the MagSafe power adapter changed states when I reset the SMC, link.

Output from Terminal:

Is it possible that is hardware problem? It works when running on battery, so I guess it is software problem? I use to fix problems on my own, but this one is a mystery
