Current draw is nly 0,03A, without change after pressing power button.

Board was water damaged with short on 13,5V power line.
After celaning and removing short on board i have 5v, 3,3v, 1v, 1,8v but no reaction to power button. Its same if i use USB-C or normal power supply.
No shorts detected (only CPU power is 1.2 Ohm, but thats OK i think) no other water damage found.
Tried to flash BIOS, no change.
After pressing power button i get orange light in front (no light on power button LED) as long button is pressed.
Advice needed.
TIA Matus.
