Hi there, I am sending in my iBook G4 1.42GHz for a repair and I have a question. How can I remove ATIcellerator?? I dont want to void my warranty for overclocking my GPU. I am senidn my iBook in because the click on the mouse sometimes works and other times I have to slam it down to click and it is growing on me. This is my 2nd repair and I am wondering if they will give me a upgrade to a new MacBook. Does anybody know what happens?
