The ibook clamshell doesen´t turn on. I press the button and he makes a signal sound like a short “bip” three times. I know that mac make sounds to inform that kind of problem is happening. But yhis i don´t know. Thank´s!!!!

3 beeps at startup means bad RAM or possible bad MLB. Best course of action see if you can find another stick of RAM to test in the machine that matches the specs.

Replace ram,if it continues replace motherboard
