Well, I have an old Powerbook G4 12" 1.2GHZ and and 1.5GB RAM, it was given to me by a Friend who had no use for it, and I thought, Hey! Why not? and took it. Finally got the battery to start charging, and well, there seems to be a problem with the WiFi antennae, the AirPort Extreme card works perfectly, but when plugged into the powerbook, only RARELY sees networks. And when it connects, it works for about 5 mins before shutting out again, any way to fix this? all I know is that to get an external antennae on this thing, you need to void the warranty. So is that my only option? Or is there some other fix?
