Hi guys,
I have Asus K55VD motherboard - Dc to Dc controller chip RT8239b is getting hot - when tested - 3.3 volts Always ON voltage is missing - but 5 volts always ON is present. Don't have schematics to trace the 3.3 volts always ON power rail . Help is much appreciated
Note: This 3.3 and 5 volts always ON will be present even before pressing power button and feeds EC and charger IC. When power button is pressed 3.3 and 5 volts system power will come out of RT8239b chip.
