trackpad is working fine. So, my guess is pull up voltage to be present since they seems to be on the same i2c chain. Am I right?
Cabling seems good, at least before removing the logic board .... maybe tomorrow I will remove the board and check on the other side.Leave a comment:

Macbook a1706, dead keyboard.
Anyone has experience troubleshooting keyboard on this model?
From schematics it seems an i2c keyboard, the problem is I can't find a good test point con scl and sda, in order to see if voltage is present (usually i2c works with the 2 rail pulled up with a resistor to a voltage source ... components attached to the two rail communicate pulling the line down.
