Clicking noise from power adapter

I have a G4 Titanuium and today when I plugged the power adapter into my AC outlet it was making a clicking noise. This is before I plug it into the Powerbook. When I do plug it into the Powerbook I cannot charge my battery. Does anyone know what this coud be. I think I will end up having to buy a new power adapter but I would like to know what has failed as it worked perfectly yesterday.

My PSU started clicking, it worked for a short period but very soon if was totally dead. I tried to open the thing but it was a bit of a mess when I finished and I wa no-where near spoting any short etc. Regret you just have to get a new one.

When I got my new PSU it wouldn't charge properly. It overheated (yes I know they get hot - this was overheated to the point where it cut out). I had to reset the Ti's PMU before normal operation was restored.

Hi,

my PowerBooks Voltage Converter started the same noise, and keeps on running since nearly a year now. It might have to do with the intenral part that is switching the voltage to 12V. I try to unplug it whenever I don't need it (unplug from the wall!)

This happens to me too, but only if I have a surge on the circuit. The charger will turn off and the PB will stop charging.

I have previously been informed by Apple (My brother who is an Elec. Engineer confirmed this is most likely the case) that the voltage-regulator kicks in and turns the adapter 'off' to protect the circuitry.

Does turning it off by the wall socket help at all?
