From our observation (we may be wrong) pressing the mainboard in the place to the right from right-bottom corner of touchpad caused it to restore from "frozen: state. It seems to be something with MainController which is nearby of point where we pressed motherboard. Finally we took a piece of paper, wrapped it (to create stiff cube) and put between mainboard and notebook cover (in the place where we pressed notebook). It helped, since for 2 weeks laptop didn't freeze at all. I was using it a lot and I suppose our cube from paper might be loosen now. It freezes again, but not as often as it used to. I live in Poland, my warranty has expired, I don't have a chance to send my laptop directly to USA. In my country HP doesn't not support Pavilion series. I was thinking about buying new mainboard but it is quite expensive. I can still try to sell my broken laptop and get at least some cash for it. What would you recommend me?
i should contact HP because this is a really common with these units
