Hello all
my problem is related to MSI MB. Simply not responding on power button. I tried to manually short power pins with the same effect. I managed to start PSU by shorting PS_ON pin with GND and I started some measurements. I removed CPU, RAM and M2 drive (I left naked MB). There aren't any voltages on the board apart of PSU voltages 3.3, 5 and 12V. I wanted to flash BIOS with the programmer but unfortunately I can't extract ROM from MSI site support. There is also missing BIOS supply voltage...
My another assumption is broken SuperIO chip, but I don't have much experience with PC motherboards.
I didn't check it under microscope yet for missing components.
Another question: is BIOS programming similar like for Laptops? I mean clearing ME region etc?
I'm using attached schematic to simiar board as reference.
thank you!
