Default Armada 7400 won't charge - clicking noise around power entry

When I plug in the power cord, I can hear a clicking sound around the
power entry area. If the machine is on battery power, the screen
flashes like it's changing from AC power to battery power and back.

I can't tell if the power supply is bad or some portion of the
mainboard in the laptop has gone out. 9 out of 10 times, I can't get
it to charge the battery.

I measured the output on the power supply ~14VDC.

Any help is greatly appreciated.

Sounds like a bad inverter board.
