i just bought a 17inch 1.5Ghz Powerbook G4 from a friend of mine. She said that the Airport Extreme Card is having issues where it won't recognize networks and is getting really bad reception when it does. (for those that do not require a pass and ones that do). Apple said her applecare warranty was expired so they offered her no help. I figured I could figure out it since I have a Airport Extreme card in the iBook I am using right now and that I could just swap it out. These are my problems though: 1) I have no idea how to open this thing and get to the Airport Extreme Card! I took the battery out, then the RAM cover but I have no idea what to do from there. All of the information I can find online is for a different version of the Powerbook then I have because my battery is in the bottom middle (front) and they show in their diagrams batteries on the bottom left (front). Can any one help me do this? 2) Even if I do get to the battery, what should I do if the swapped Airport doesn't work. What actually goes wrong with Airport Cards? Do I just need to adjust a setting rather then actually replace the wireless card? Thank any of you that can help!
