Request for Help – ASUS G531GW Rev 1.6 – No Power On

Here’s what I’ve checked so far:
- Motherboard has been removed for inspection.
- 3V and 5V always-on rails are present (3V/5V_ALW).
- 1.8V and 1.09V at the PCH are present.
- I don’t have the boardview/schematic, so troubleshooting is limited.
- I tried checking the power button signal from the keyboard connector (embedded power button design).
- Only two pins show voltage:

- Pin 5 from the left has 3.2V
- Upon applying power, the measured current consumption is 0.04 A
- All other pins have no voltage.
