I don't have an external display. I'll try to get a borrowed one.

I did it when I send it to service, they saw the "problems", but they 
couldn't give me the warranty service because at the moment they 
weren't an autorized AppleCare center. So the book had to "travel" to 
an autorized center, where as I explained before they reported that it 
was a software issue. They returned the book almost 2 months later 
without haven't done anything to it. At the beginning it worked "fine" 
(I got used to the wake/sleep problem) but the problems began again.

The book has the original Apple RAM, I haven't added 3rd party RAM.
