Are you ok for fix U9410 like that?( PIN 6 PIN 7 to C9410 PIN 1).

Magsafe with greenlight, but no boot (without battery).
So Now Macbook boot with battery only.

So? You run 2 small wires. But first I would try and power on the board with a charged battery, the whole U7000 circuit is not needed for that.
