My laptop won't charge

So last night I was up playing a game and the charger slipped out, I only realized when the laptop itself starting saying it was dying and when I tried plugging it back in it wouldn't charge. I've checked all the parts to make sure everything is connected and it's still not working. On the block for the charger there's a small light and and it's green so I know it's on (I use a UNNO Universal Laptop Charger) I've made sure the port doesn't have any dust or lint as well so I'm not completely sure what's happening.

I also can't turn on the laptop to troubleshoot it because it's dead so if the laptop is the problem then I can't check manually

I use an HP laptop (not completely sure of the exact model) but it doesn't have an exterior removable battery so I can't immediately see if the battery was the problem

Prior to this the charger worked completely fine and my laptop hasnt had any issues charging or staying alive so this is completely out of the blue

If anyone can help I'd extremely appreciate it!
