My G62 b10sp went blank yesterday....in HP they say that the ATI GPU responsable for it, is replaceable...wrong...we must replace the all motherboard...mine only work in safe mode with the Intel GPU. I tried to search the motherboard part in HP partstore and cant find it....terrible...only find motherboard to buy on third party sites and it was very easy to find it...
In the official HP site you jump window to window without finding anything....
My laptop only lasted 2 years and 6 months...my next laptop wont be an HP for sure...
