#1 HP Pavilion 14-CK (GRANGER 6050A2977601 MB A02) - 0.02mA after power button

Laptop = HP Pavilion 14-CK
Board ID = GRANGER 6050A2977601 MB A02
Hello, i am looking for some help with this board, When the adapter is plugged in, the DC jack light is on as normal. After pressing the power button current consumption will only rise to 0.02mA for several seconds then drops back to 0.01mA.
I can not see any physical damage to the board and all the resistance on the inductors seems to appear normal. 19v is present and the KBC has 3.3v, but no 3.3v / 5v or anything else after pressing the power button. I have attached a picture of the board with the resistance readings to the corrisponding inductors.

I believe the 3.3v IC (L8=5A) and 5v IC (L9=5H) are
3.3v = RT6256BGQUF
5v = RT6256CGQUF
Can somebody help me in the right direction on how to further diagnose this board.
Thank you.
