I have a macbook pro 15" model A1226. Before it had a problem with the graphics chip, and the screen would not turn on. I reflowed the nvidia chip with a heat gun, and now when i put it back together, the mac boots up fine. but the keyboard and mouse do not work. I am able to plug in a usb mouse and use that. Also currently this mac boots into windows xp, but i believe that it does have the mac os installed still, just dont know how to boot to it. How can i fix the keyboard and mouse on this? Will I have to do another reflow on it?
