I am having bitter experience with HP Pavilion series with AMD processor.  

After giving it to Redigton (HP’s only authorise Service Center) for many times they told me that they are getting lots of complains for note books with same config. AMD processor generates heat and that damages the board (they replaced it twice in my note book) and other parts. It also reduces battery life. In my case, it runs for only 35 - 40 minutes even after choosing all power saving options.
