It is impossible to know what touched what inside your laptop. If the two power wires from your AC charger broke off of the laptop board and then touched eachother, I would assume that only the charger is dead. If one wire from the charger broke free and then touched some random PCB trace on your motherboard, then who knows what is damaged (could be anything on the laptop OR your charger or both).

I would disconnect the power, check out the solder joints, fix them and try again. IF you get a dead response, then borrow a charger from someone else to determine if it is your charger (with the risk that you could damage that charger too).

Poor soldering will do tht.
You are way out of your head to fix tht, since you did not realize a laptop will take atleat 3Amps to charge a discharged battery. I believe what happened was due to the fact that you did not melt the solder enough to let it flow to both sides of the board.
I just cannot imagine how to start to tell you what to do without closely examining the motherboard.

I cannot make videos.
And if you have no electronic repair skills I cannot guide you.
Repairing mother boards is not easy and definitely not for beginners.
