Type dv9000 recall into google to learn more (but you did that.)
Sadly not typical of your usual 5 year design life. So what's nice about laptops is they have plummeted in price to the point that service will now cost more than a new laptop.
I currently have a 10 year old HP tower and a 5 year old HP Tower and almost 3 year old HP Pavilion dv9000 Laptop.....Knowing that both my towers are still working great through my great computer preventive maintenance, I was shocked that my laptop graphics card died before even reaching 3 years old. While discussing this with HP and finding out that many of dv9000 series had to be "recalled" or extended a special warranty for this issue...(my model not included) I was told by HP that the average life span of a laptop is 3 to 4 years regardless of brand. I would like to know if that is true of all brands before I consider my next purchase. THANKS
