Hey i use to have a dv 9930 us but i got an extended warranty from hp so i was able to exchange the computer. Unless you really want to keep the computer toss it out and get a new one. My dv9930us had problems in every single system and the total amount of time i spent on the phone and my computer was at hp was about one month total. Get a new computer because even though they clam that the computer's defects have been fixed they really havent. All the parts that have a problem are: the motherboard, the heat sink fan, the left hinge on the laptop, the graphics card (it caused a class action lawsuit), About the only thing in my dv9930 that didnt get replaced at least once was the wireless internet card.
