3-Voltage on pin number 32 is 3.3v (ENE Chip)

PHQAA_LA-6831P.pdf does not match those pins.

Check voltage in all pins of power button. Drop voltage to zero while pressing it?

when pressing power button the voltage on ENE chip pin 32 becomes 0.0V but the PCH_RSMRST on pin 100 should come out after pressing the power button but in my situation the voltage is still appear even if I pressed or not

so please what should I do in this case ? it is Core i7 CPU !

thanks
