Hi, Please I need help from all of you guys, yesterday I bought a PB G4 550mhz used for my wife but I havent noticed the failure in the plug. Yesterday the plug was in and the pb working but at night once the battery was fully charged we unplug the ac adaptor and a couple of hours later when we try to plug it again, we can't do it. Please help me through this, where can I buy the parts need it to fix it. As far as I understand seems to be the plug was damage please see the pics at http://homepage.mac.com/nandohdez/PhotoAlbum3.html Please send me your comments. Carlos
