[ltp] T61 system board (42w7872)

[Jason Brooks]

There isn't a fuse on thee board it would be a resistor. Chances are
it is a chip on the motherboard that has deballed or gotten so hot the
solider has separated from the board. There are two options( or three
if you can reflow) new main board or get the board repaired by someone
who can reflow or reball the chip that has lost contact with the
board. The chips that typically do this are the graphics chips. They
get really hot for obvious reasons.
