MSI Prestige 15 ms-16S6 won't power

[Dr.d]

parkhayoun...You said you already replaced the motherboard and same problem? Or, are you saying that you have this "New" problem with the replacement motherboard? I've searched all over the place for schematics and cannot find anything. I'm pretty much at a dead end with no more ideas with my MSI MS-16S6 problem. Found 1 issue with the FLASH IC not getting 3.3v . Fixed it, but still no power and no charge.

I replaced the whole motherboard and yes. I am stuck in the same problem. Believe or not, I can't believe that even changing the whole motherboard results in the same symptoms. So my next doubt is my battery pack or keyboard matrix is not working so the power button is not recognized. that's why I'm finding the schematic or boardview file to bypass the power button and the battery pack.
