I have a hard time believing you have continuity on those traces, that first one nearest the battery appears completely gone. What points are you using when testing it?

follow trace to right hand side . Meter point into the small through holes .

Second point of probe onto the pins inside the c10 connector .



But I was also shocked when I looked close up at them lines so roached.. data ain’t going to be ok on them lines .. in which case that’s good thing I can now work on adding new traces on the underside ?

I'd chalk that up to a UniBIOS 4.0 glitch. As for the battery damage traces, check the pins on the connector. Do you have continuity from the top board to the bottom board? If the battery corrosion goes up the pins to the upper connector you'll lose the connection there.

I have connectivity to the top board
I’m checking the top side of the conector when both boards are together.
