Hi there, im having this problem after my girl trip over the charger cord, it unplugged the Laptop and then it wasnt turning on at all,also the charging led was off, so i opened it and there was this little piece brown , it was burned or something, (img1

) (i do attach 2 pictures of a "healthy" motherbard and a 3rd one of my motherboard) so i try to solder it again, after doing that it now turns on and i see the charging led on now, but only lasts a few seconds turned on, right before windows starts it just to turn off again. so i try to solder better but my soldering pen is pretty bad, so i messed up this 3 soldering points. (img 2

). The problem still the same , start and then turns off. So if there is anyone that can tell me the name of that component, and if you can spot any mistake (beside the bulks ) , i really would appreciate so much!!! thank you guys for your time and any ideas. have a great day!
 
Solution
You'd need a schematic, or maybe tech support could help you.

I can't even tell if the component (resistor?) is still on the board, and there may be other problems as well.
