Laptop Power System has problem: Laptop Asus K55VD won’t turn on at all, probably some electronics components or chipset on the motherboard failed;  Disassemble the laptop and take out the motherboard. Look for any burn electronics components(fuse, SMD capacitor and MOSFET …), check chepset temperature (CPU,  GPU, Power-Supply IC …), with a Multimeter measure voltages on coils, check for any components shorted to ground,  you will need an electronic boardview or Schematic Diagram for Laptop Asus K55VD. The failed electronic component has to be replaced.

    Solved Problem:
    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 .
    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.
    EC ITE8517E gets 3.3 volts standby voltage from RT8239B system power controller. When EC is short no 3.3 volts and chip gets hot. Replaced EC solve the problem, all good.
