Why is my PowerBook not starting. (you here the chime)
I have a Powerbook g4 that doesn't start.
When i start the powerbook i hear the normal apple sound but then the screen stays black.
I tried to replace the battery with a new one, nothing changed.
I replaced the PMU board, nothing happend.
I have an emergency solution: I remove the battery and charger, then I replace them, then I press the PMU reset button on the back of the powerbook, I wait for like 10 seconds and then press power.
In this way the Powerbook starts normaly, but in this case I can only use my powerbook when i'm at home.
I tried to reset the PMU, PRAM and some other trick that was mentioned on a forum CMD+option+a+v.
Is there anyone that can help me?
