Hello

I have a problem with Asus FX504 laptop. 

There is no power on it and I can't find any short on MB. 20V goes throu main rail to a TPCA8065-H mosfet. And on this mosfet comes out on drain only 8V. There is no V on any other rail.

I have changed the mosfet but there is still the same problem.

Can Anyone help?

Thank you
