iBook g4 stops on the apple logo when I power it up

Es esta una buena pregunta?
First, it's dangerous to use a computer without battery, cause when the AC adaptater is unplugged , the machine suddently shuts down, and this is not recommanded for computer health ( It can damage files, hard driver, or something else) . So don't do it again.
According to what you tell us , I can say that there is 2 possibles causes:
1-Your files has been damaged, so that Mac won't boot
2-Your RAM Memories can be damaged too.
Try this , and tell us more about after doing them:
1-remove the RAM memories and try each one of them separately (plug one and try , then plug the other and remove the first one and try again.
2-At Start up , press "Commande+S" to boot in single user mode and type
"/sbin/fsck -fy" exactly like this ( there is a space between "k" and the dash.
Do it until you get this message : The volume _name_appears to be OK!
and type "reboot" to restart the mac.
3-if it won't boot, you will have to reinstall it .
4-Force mac start up holding "Commande+control+powerbutton"
If all this have help you, post us back and I'll suggest you more solutions.
