lol , i 'm also victim of HP dv 9000  after i used it for 2 years , then came to find out that dv 6000 and 9000 series all have problems,my went to the  black screen ,then i disassembled ,bought heat gun and thermal paste ,and heated nvidia microchip for 3 minutes to melt solder  then applied thermal paste and penny also and still didn't work and finally i threw it ,many of them works for sometime after applying heat on gpu to melt the solders  .It's the design flaw from HP and they faced lawsuit also ,i will never buy anything that's HP .
