EDIT:
The component you posted is indeed U2150 on my board view as well
Since its connected to PM_PCH_PWROK, I would not be surprised PM_PCH_SYS_PWROK is low for you
i am of the same opinion as you, but you usually charge 50€ more in my opinion it should 100€.. But i work for others and i have a boss!! i do not usually wast time in this boards but sometimes a different idea solve the problem.. i already realize this board this board will be difficult to solve.. You can close the post.. Thank you Duke
