I have a 3400c/200 sitting in pieces in my basement. Last time I tried turning it on all it did was click once and not work. Anyone know whats wrong?
This was at least a year ago I tried starting it up last time so my memory is a bit fuzzy, but ask if more info is needed.

Does the green sleep light stay on, too? If so, try resetting the PRAM a few times. A more thorough reset would be to take the battery out, disconnect the power adapter, press and hold the reset button on the back of the computer for at least 30 seconds, then plug the power adapter back in and try turning it on (if it doesn't come on automatically). That sometimes works.
If it still doesn't work (and you've ruled out things such as unseated RAM cards, bad power adapters, etc), then there's a chance you've got a dead power board.

Just leave the adapter plugged into it for a day or so if it hasn't been during this time. Then try turning it on (perhaps after resetting the power manager).
Also carefully inspect the board near the pram battery. The NiCd cells can leak and wreak havoc on the traces nearby. If you see evidence of corrosion, sometimes a careful clean will solve your problem (assuming that the corrosion hasn't progressed too far).
