    820-3462-A - 7ukm keys doesent work

    tested with other keyboard and the same, found some currusion on U5701 and renewed the pads but no luck either, my question is how do I figure which dead line those missing keys belong to, when I look at the U5701 in the schematic I cant figure which pins is responsible to which keys.
