    Usually there are resistor networks related to the keys on Mobo side. Unfortunately no clear picture of the bkard shared, but worth to check I guess, before messing with the EC.

        check connector solder joints. measure in diode mode, if the connector pads are connected with ec and look for abnormal values. maybe the ec is faulty

        hope schematic helps

          u10 looks a bit displaced, did you work on this already? also check ec solder joints then

            "Displaced" is a good call.

            This has to be sorted of course. So we have a NOT mentioned repair attempt in this area. I teally want to ask the thread starter how we should troubleshoot that without asking the crystal ball?

            Full history of the device please!
