I have a 3000 that I think needs a new...everything. Needs a battery, buttons missing, broken disk drive, no screws...
But I'm pretty sure the motherboard is intact. I can't do shipping though, sorry.
Um... is the thing working otherwise? When I think clicking noise, I think tiny arcing when you cause a short circuit. if it charges, I wouldn't worry about it.
If it gets hot, start worrying. If it starts smoking, ditch it and run.
