Hi, and welcome to Apple Support Communities.
Have you tried resetting the PMU?
The PMU (Power Management Unit) controls trackpad function, so resetting it often helps when the trackpad isn't working (or isn't working right).
Hi Ronda
Thanks for answere me
I've tried to reset the PMU following these istructions:
But nothing changes...my trackpad doesn't click
I've tried also to reinstall tiger from the beginning without use any external mouse...but nothing changed...
don't understand, a few years ago I remember to have reinstalled tiger but with no problems at all...
Is there any mode to reinstall the trackpad driver?
Do you have the original system discs that came with the iBook when it was new?
yes I have used the origilal discs that came with the ibook...I suppose that apple doesn't care anymore about ibooks so the updates are not accurate as before 'cause I'm sure that last time I've refreshed my system the trackpad worked fine
maybe I have to download a new copy of tiger? my original discs are:
iBook G4 Mac OS X Install Disk 1:
Mac OS 10.4.2
AHT version 2.5
Disk version 1.0
2Z691-5532-A
Mac OS X Install Disc 2:
Disk version 1.3
2Z691-5533-A
Check out the Archive and Install section of this Apple Knowledge Base article:

Do you know if you have enough available space on your hard drive to accomplish the Archive and Install?
thanks for the help, but I don't know if "Archive and Install" will help for my problem with the trackpad 'cause when I've refreshed the ibook I've used the option "Erase and install" so everything of the old system is gone...
I suppose there is no solution to my problem
P.S. thank you for your time :-)
Since you've already done an Erase and Install, I would suggest trying it again.
From the Apple Knowledge Base article:
Erase the Mac OS X volume, then restore Mac OS X and all bundled software
Important: This option erases your destination volume (it deletes everything that's on it, including files on your desktop), so be sure that you've backed up your stuff before committing to this choice.
I'm sory to get back to you so long after your original question Allesio, I have resolved the same problem by buying a corded mouse, plug it in, restart the iBook g4 and that's it!
Even the genius bar guy couldn't figure it out.
Regards
Well, I'm glad the mouse works for you. At least you can continue to use the iBook.
