Asus Fx503V laptop that won't turn on

Hello,

My Asus Fx 503V laptop, just out of warranty, won't turn on at all; all the indicator lights remain off.

I checked the charger: +19V OK

I tried pressing the power button hard for 30 seconds with the power unplugged, then plugged in, but nothing happens.

I disassembled it (see the 2 photos)

- checked the 2032 3V battery: OK
- removed the battery and powered by the charger: nothing happens
- I checked the voltage:
--- charger unplugged, battery connected: 0V at the battery terminals
--- on the connector of the power input, charger plugged in: 19V
--- at the battery terminals connected and charger plugged in: 0V or close

- visually, there are no abnormal traces on the surface of the motherboard.

Are there any other simple tests I can do before I throw it away?
What do you think?

Thank you in advance for your advice

    Hello,
    It seems that the charger is no longer doing its job and maybe the battery too!
    What is the purchase date of your PC?

      As I mentioned:
      - I tested the charger: 19v OK and I also tried it on another Asus and it works.
      - it is out of warranty (2 years): purchased in February 2018.

    Hello,
    If you have 19 V there,

    without going through the battery and with the computer started, the fan should already be running, have you checked?

      Hello,
      Indeed, at this level I have checked with the multimeter that there is a stable 19V, but nothing is moving, neither the fans nor the indicator lights which remain off...

      Have you tested the power button on the PC? Is it functioning when activated?

      The on/off button is not the issue, I tested it and it's working.
      The problem must be with the battery that is not charging while the motherboard is properly powered... so there's an issue with the motherboard... too complicated to fix for me... it's going to the dump... I'm only keeping the 8GB of RAM and the HDD... and I'll avoid Asus laptops in the future...

      Thank you for your advice...

      If you think the motherboard is the cause of the issues, there must be a way to find a second-hand one, for example.
      Does the cable supplying the battery have no voltage?
      See you later!

      Yes, that's right, the cable that powers the battery has no voltage, while the motherboard is properly powered at 19v.
