Asus TUF Gaming FX504GM DABKLIMBAB0 - No POst, Turns OFF after a few seconds

[limxrich]

I would say this is a no fix, but want to pick the brains of the veterans here.

All voltages present, already tried several BIOS bins. All voltages present when power button is pressed. All reset signals present. Unit does not post, but turns off after around 10-12 seconds.

Some interesting details:

1. Unit toggles from 7 & 12 mA when plugged in
2. Units goes up to 1.5A when turned on (10-12 secs)
3. Current toggles between 37mA & 42mA when it turns off.
4. Unit is on continuously ON w/ all voltages present when no RAM is present.

Thanks in advance!

Without ram ,system doesnt go to S0 stage and hence not getting off. Seems like some problem in S0 stage. I'll suggest to check all powergood signals one by one for the brief time when system remains on. The measurements should be with ram stick.

Thank you for the suggestion. I checked all powergood signals and everything is on the right voltage (1.8V or 3.3) depending on the signal.

Any other suggestions?
