AN515-58 12500H 3070ti-Burnt capacitor found on GPU area in the motherboard, how to fix it?

Psyhodel1c

While cleaning the laptop from dust, I removed the cover, removed the fans, cleaned everything and put it back together, when I was putting it back together, I examined the cover from the inside and saw a black leak. And then I saw something on the board that shocked me. A capacitor burnout (probably) somewhere in the GPU area .... This clearly happened earlier and has nothing to do with my manipulations because there is an old mark on the cover, and there is no smell of burning anywhere. The question is what is it, why could this happen? And the main question is WHY does the laptop work in normal mode, I ran AIDA + FURMARK stress tests, I launched heavy games like Stalker 2 or Cyberpunk 2077, everything works clearly and stably, the frequencies reach the factory settings, everything is perfect. Is this some kind of backup capacitor? How is this possible and what to do about it?

I'm not strong in electronics, but it looks like it was burned out because of a bad contact, 

and the laptop has never been repaired, because the smd element itself is in good order and the ceramics are intact,

but it burned out at the point of contact with the board. Lack? Poorly installed at the factory?

 Looking at how many such SMD capacitors are on the board, it becomes scary)

 But I still wonder WHAT kind of element this is, who understands boardview or knows, please tell me
