Picked up an HP a630n for free with bad caps. The CPU heatsink was completely clogged. The 4x1000mf caps are bulging. I assume these are the VRM? What really bothers me is one of the ferrite donuts with the bright copper wound around it, 3 turns x 4 positions. On one of the four, the copper is black and the donut appears to be broken or brittle. Since all this is right up against the heat sink, I figure that contributed to the failure. On this model, the PSU has a green led on the outside. It's on until I hit the power switch, then it goes out. On unplugging the AC, it blinks on once after a few seconds. Disconnecting the 2x2 yellow/black connector on the MB before power up will keep from killing the PS, but of course still doesn't do anything. Just wondering if this board is worth me repairing.
Thanks,
Dave
