This expensive notebook hardly lasted two years and then broke down because of a manufacturing mistake: components on the motherboard are insufficiently isolated, get overheated and burn out.
Read the posts on the HP forum about this issue:

DV9000 Video Chip Failure; LCD not working & system will not boot
HP Pavilion dv9000 (and others) Overheating Damage/ Motherboard Failure
Installed operating system:
This system was initially running
Windows Vista Home Premium (SP 2)
However, to make it more stable, it was downgraded to:
Professional Edition – Service Pack 3
Note that in both environments it suffers of poor nvidia driver support.
Warning to all laptop users:
HP Laptops suck ! Don’t buy them.
