Recently a friend of my give me his Tibook 400 because he bought a ibook g4. There are only 2 bad things with the computer, one is that battery won't charge and the other is that the screen has 4 vertical stripes. For the first problem I think it has to do with the pram because my friend told me that a week before he gave me the tibook battery was working fine. The seccond one ... hmmm, I don't know, but if I flex the screen a little I can make the stripes dissapear. Any suggestions?
