Why is my MacBook Pro not charging?

My macbook pro had still 15 % battery when I noticed it wouldn’t charge anymore. I tried charging with my charger and it wouldn’t work. Then I tried my charger on somebody else’s laptop, to check if it is the charger and that would charge. Then I tried charging with the other persons charger (which also works on her macbook) but it wouldn’t charge on mine.

I tried “resetting the SMC” a few times and did a battery check when the laptop was still working and everything seemed ok. Now the battery has died and I cannot turn it back on.

Does anybody have any idea what could be the problem or what I could do to fix it?
