I definitely recommend seeking professional help. Last October my keyboard and powersupply started acting up on my 12'pb. I remember that my G3 pb keyboard just popped right off so i figured i'd do the same thing and investigate. I used my Mr. Burns strength and pretty much broke my keyboard and it ended up costing $650 to repair the logic board and get a new powersupply. Guess I should have been patient but I was pretty far away from an Apple authorized repair option...
