HP 15-n051su (Quanta U93 DA0U93MB6D0) does not power on...

Hello guys,
I have this mobo /and whole notebook/ for diagnostics /and repair if I can /. There is no schematic for U93, so I'm using U72
DC-JACK is broken so I guess there are 19V on AD_ID line.
3.3V/5V - RT8223P was very hot, so replace it with TPS51125.
Replace dcjack cable. When plug adapter, orange diode blink for a second and that's it. When pressing power button, voltage drop form 3.3 to 0.
I try to check AD_ID line. I found R336 and replace it, but I can't find R344 and D8 diode. On R336 I have 1.08V at one side, and 0V on other side. Can someone tell me where is R344 located /if it's present on this board/

Edit with additional info:

after replacing IT8528, dcjack led lights white, notebook power on, but there is no picture and fan no spinning.
I check PU9 /NB671, code on the chip AEAD 748, I think it's this one: https://www.monolithicpower.com/DesktopModules/DocumentManage/API/Document/getDocument?id=823

I check this from Quanta 92 schematic, because on Quanta 72 i think it's different IC.
On pin 13 must be VRON from IT8528 /same signal goes to cpu power/, but there is 0v on NB671. VIN present. VRON /3.3v/ goes to NB671 through resistor PR282, but I can't find it on the board.
Can someone help me where to find it?
For testing - make a bridge from IT8528, pin 83 to NB671. After that, NB671 generates 1.2V, but still no picture on the screen.
I need an advise..
