I have a 12in G4 PB and its been dropped a couple times whatever, its 3 years old, but still running strong (minus the optical drive hah) but the more pressing problem is that the plug in now is reeealllly finicky. I've had to sorta push it at an angle for a little bit to get the connection right, but now it goes back and forth between plugged in/charging. Also, its harder to obtain that connection than before. What's my problem? The Adapter or the DC In? Thanks.
