DV6400 Board is toast

[sparker1]

Have a look at this board. I bought the laptop (HP DV6400) it thinking it might be an easy repair. It had a dead short somewhere as it tripped the lab supply as soon as it was switched on. The pictures show some small component has blown but has burnt the traces through the board to the other side. I guess that's the end of it. I'll try and identify the part from the schematic and scrape off the charcoal then see if anything can be done. woe is me.

Yeah I think it is done for.

These boards can have many layers, so some traces that you can't see on the outside might be damaged.

Either the component shorted and caused a trace or via to burn up, or the other way-around...

The board is mortally wounded. There is actually a 1-2 mm hole that goes right through the board. I'll try and source another board rather than write the whole thing off.
