Laptops are a completely different animal when it comes to DIY stuff than desktops. Most laptops are built to a pre-determined specification and thus, every aspect
about the laptop is limited, including:
- Mechanical: Not just if the part will fit, but if the cooling system is designed to accommodate the TDP
- Electrical: If the part meets the voltage requirements, the pin layout, and if the power supply can handle the part.
- Software: If the system firmware is happy with the part.
These limits restrict you to what you can and cannot put in the laptop. The only way you can be sure a part will work with the laptop is to figure out its range of configurations. If the laptop did not ship with a particular hardware configuration, then 9 times out of 10, it won't work.
Now about your laptop and about that GPU... First and foremost, do you even know what BGA is? Also considering that the dv9000's GPU is the GeForce Go 7600, you're more than likely looking at a different pinout and power requirements. That and the 9800M GT produces a lot more
So do us a favor, stop spamming your own topics and go actually learn what the fuck you're doing.
