"One does not simply remove the GPU in a laptop,,
You could try the oven method though i fixed a HP DV9500 that way... it failed 1 month after :(
Then i did it again... One month after. And the i tried a third time at i gave it too much time in the oven, so i destroyed it with a hammer :D (Rest in pieces DV9500)
But i have seen a HP 8510w or a very similar machine form the same time (Core 2 due, Quadro graphics, same size and construction) Very nice laptop sad to see it end like this :(
