Hi help needed Im working on Asus x550cc rev:2 matherboard.
when press PWR BTM all signals (+5VAO +3VAO SLP_SUS 3VSUS_ON 5VSUS_ON +3,+5VO UNTIL PM_RSMRST) Present
Except (AC_IN_OC & ME_AC_PRESENT).

I have tried reflashing the bios but still the same.
Any help appreciated.

thanks.
but my mainboard does not have on board memmory.
Posted after 15 minutes 30 seconds:
when i power it on . it takes 12MA stable.
i change the (south bridge- IO-charge PWM)
but it is still the same az before(12ma).

which test point should i test?

I checked the test point.
AC_IN_OC signal Is not present.
where does AC_IN_OC comes frome?
or
what is wrong, that cause this problem?

The best way to understand ,what is wrong is check the test points using repair guide. Try - download/file.php?id=58222 Take a photo of your motherboard and release here, please.
