sad to say as of now, today, this moment, my g3 ibook's logic board has (i believe) passed away. very disappointed mind you since i JUST bought my powerbook, and had sold my ibook to my mom for emailing, which now she can't use. has anyone recently done the logic board replacement? what is the cost? i have no apple care plan, and i am not the first owner of this ibook. hlp plz.
