dude....hp pavillion sucks man....i had the same problem as you have mentioned........i had bought it just a year ago....handled  it with great care coz it was the first laptop which i bought after my great savings...but unfortunately the screen came black without my knowledge.......hp service center sucks tooo...they charge you more than you have ever imagine if you go beyond ur warranty date...so my recomendation......leave it in ur closet.....or if you have money try to buy another one rather pavillion....i'm using sony vaio right now....so understand my moral....""hp sucks""
