I cruised by the HP Web Site the other day and found they had a new bios update for my computer. Downloaded it and ran it and thought so what. Wrong. It caused all kinds of BSODS. Problem was that it would not let the computer come out of sleep at all. Once out of sleep it would lock up nice and tight. Well, now until HP decides what to do, all I can use is the screen blanker and thats about it. Funny thing is, HP withdrew the update the day before yesterday. Guess I know why! Anyway, there's always the danger that something new will have problems. And I got bit big time by this one.
