Razer Blade Pro 17 (Mobo: F2.5_MB MP V4.0 20170810) - not powering on

Hello Everyone,
I am looking for help to identify the problem.
This one is Razer Blade Pro 17" powered by a 7th gen Intel Core i7 processor and NVIDIA GeForce GTX 1060 graphics.
3.3V and 5V are present only until I press power button. After pressing power button there in not any laptop reaction but 3.3V and 5V both goes to zero and 3.3V is not coming back on power button.
I have to disconnect power and connect back to have 3.3V and 5V present again.
All fuses were checked on motherboard and all are OK.
Resistance to ground on all coils looks OK except GPU area. 0.67 Ohm for GPU looks OK but 2.29 Ohm is low, I think (possibly VRAM power but I have not found schematic anywhere to confirm).
The only test what I could do was with thermal camera. When I press power button PCH is warming up (normal temperature) but after like 10 seconds is off.
Has anyone had similar problem and can help with mine please ?
Thank you.
Regards,
Rafal

Cześć,
zmierz rezystancję do masy na wszystkich cewkach.

Jaki prąd pobiera płyta po podłączeniu zasilacza, a jaki po wciśnięciu włącznika?

Zmierz napięcie baterii RTC.

Hi,
Thank you for your help with this one.
I have measured resistance to ground on all coils.
I could not find boardview or schematic for motherboard and I was not sure if you have one.
Instead of providing list of coils numbers (which would not make sense without schematic) I took the photos:






When I connect power I get 29mA, in 1 second jumps to 40mA, 1 second after that goes to 11mA and stays there.
After pressing power button 11mA jumps to 100mA and after 2 seconds goes back to 11mA and stays there.

Original RTC battery has 2.9V. I have done test with new 3.3V battery but this has changed nothing.
