OK, I have an iBook G3 with a busted logic board. I sent it away for someone to weld something, and that fixed it for a few months. I do not want to pay $75 dollars to get it welded again, because I feel like at this point I could try it myself. Does anyone know of any tutorials, or like some step by step instructions, on how to open this baby up, and where to weld? Thanks. Edit: I heard there is an easier way to do this, wedging something into the LB and attaching it with tape or something. This would be preferable. Any ideas?
