No its 3.4v, i was using a second keyboard, tested it with another keyboard and it does attempt to power on with J6955 connected. so perhaps that was related to the test keyboard.
I did notice that u6990 had corrosion around it, replaced u6990 and c6990 already, could anything else in that circuit affect the bmon amon ?
If i cannot resolve this would larossmann like to attempt a wholesale repair on this for me? i could mail it out to you for service. DM me if you would like to give this repair a shot.
