Hi all,

I want to get some insight about current issue I have.
The board does not respond when pressing power button.

Current board status.
5V and 3.3V is OK.
Power button has 3.3V
BIOS and EC flashed from known good dumps.
EC is IT8528E and has been replaced with new one.
CPU voltage power supply (ISL95857) has been replaced with a known good one.
The same issue before and after some parts got replaced

Thank you in advanced

IT8528E AXA? EXA? FXS? You need to change only on the same. Check RST PCH.

Thank you for your response, zoomzoom.
The original EC is FXS, and the new I replaced is FXA.
I am not sure if they are different.
Since schematics is not available for this model, I may not be able to find RST PCH.
I really appreciate your comments.
