Hi everybody,

I'm repairing the mainboard of an HP Compaq nx8220, and the schematic diagram will be a great help. Anybody?.

Thanks in advance.

Thank you pickit2,

I already have this one, it is mainly a general maintenance guide, concerning dissasembly, flowcharts, and the like. I need something "deeper", like the mainboard schematic, to help me follow the DC lines. I changed several CMOS transistors which were shorted, but I still have a short in one of the DC lines which I'm not able to discover. Maybe is one of the small BGAs underneath one of the north or southbridge chips, which it is shorted, due to an overheating...I hope don't!, it has 609 balls!.

Thanks for your effort anyway. I will keep on searching and waiting for somebody who can help.

Cheers!
