iBook play start-up song when turned on but nothing else

[carlos.mrtez]

Help:
I'm new with this, My ibook plays the little loading tone when i turn it on but nothing else seems to happen. no more lights on the board no nothing the only thing that does s that it change the color of the charger plug, play the song and on the bottom where it goes the battery turn 3 lights like if it where loading something, i guess it means there is power in it. Also if n that moment I click on the mouse does like if it were doing someting
Thanks in advance
