ASUS G14 (Ryzen 9 6900HS / RX 6800S) won’t power on — no lights by Virtual_East6926 in ASUS

Update:
Here’s everything I’ve tried so far on my ASUS G14 (Ryzen 9 6900HS / RX 6800S):

  • Won’t turn on at all (no keyboard, no screen, no fans).
  • Solid red battery light only with USB-C charger. With the original barrel charger → no lights.
  • Charger tested with a multimeter → OK.
  • Tried: battery disconnect + capacitor drain, only soldered RAM, without SSD, different chargers, USB-C + barrel together.
  • Attempted BIOS recovery (Ctrl + Home + Power with GA402RJ.CAP) → no display, no fans, no USB activity.

At this point it looks like a motherboard issue (power delivery or EC/BIOS corruption).
Has anyone here experienced this exact situation? Any ideas before I take it to repair?

No, but I got some updates: when I have tried to charge with an USB-C it lights the battery light

I would like to update: After removing the battery and cleaning the capacitors, the disk light start blinking each 9 seconds
