On USB-C amper meter --> votlage is 20v. PPBUS_G3H is 12.61v. After about 10 seconds it goes to 12.30v and then back to 12.61 stable. U9080/580 placed on the board. Both chips there. Both chips are taken from the donor board.
I used a thermal camera to shoot what temperate pattern on board. So U9580 is getting warm first then the SSD chip U9400 is getting hot. Check the picture below. there are 8 SSD chips on the board and only this one is getting hot all others are quiet cold.
