Need help with laptop: stopped charging

Hello! My Acer Predator Triton 300 just suddenly stopped charging. Now it's just dead. I've tried using a similar charger but nothin happened, so I'm guessing it's a charging port issue.

Anyone know how to fix this at home? Or maybe know anybody in Stockholm who could help me fix this?

Thanks in advance!

Yes 2020 i think, and I bought it around that time also.

Okay so either battery or charging port then. Im hoping to find someone to check it or coach me through checking it.. I've never opened up a computer before
