ASUS X509FAC no power to board

[someonenotyou]

Hi.

I have an ASUS X509FAC with no power going to the board.



19V gets from DC Jack to PQ8901 and PC8915 but not further (PC8915 should switch on the PQ8901, correct?)
But, after PQ8902 I get 3.2V on AC_BAT_SYS.

I am at loss, as I cannot find any shorts and don`t know where else to look.
Any suggestions, please?

Thank you.

Typical reasons are a failed charging controller or missing ACDET caused by a failed DC-IN Jack.

Do you have clear pictures of the whole board for us, front and back?

On PR8904 (RES 127K OHM 1/16W (0402) 1%//TA-I/RM04FTN1273) I measured this:
Pin 1 A/D_DOCK_IN - 19.77V
Pin 2 P_CHG_ACDET_10 - 0.671V

Here are pictures. The best I could make:

AC_BAT_SYS is NOT shorted to GND, yes? Confirm please.


If not, we need a close up of this area here.

And a close-up of the DC-IN Jack too please
