Ok gang I'm still new here so please bear with me. I have an iBook g4 14in" and when I am using it the computer goes to sleep like the battery is going to die. I move the power cord around and it starts to work again....The off and on off and on for about 5-10 min why I fight with it. I have to sit the power cord in there just right to make it work. My question is this....Does this sound more like the power cord has a short (which it doesn't appear to all is intact) or is it the DC IN Board.
