Sounds like static discharge fried motherboard. Its dead jim.
I was taking the front cover off my Vosrto 460 to add a DVD drive and forgot to shut it down first. I must have bumped something as the screen went to displaying nothing but digital noise "snow". I shut it down, and now I only get for beeps and the power button flashes orange. I tried taking the memory sticks out and cleaning them, as well as pulling the CMOS battery, but still won't boot. Is there something else to try, or did I fry something in my Motherboard?
