most laptop power supplies produce 18 Volts to 20 Volts usb uses 5 Volts

It looks like the the motherboard is damaged as the laptop will not switch on.

Try removing battery (and power lead), pressing on button for about 30 seconds, replace battery and see if it will then switch on

Only an expert can decide if the motherboard can be repaired or needs to be replaced.

You probably need someone who specialises in your brand of laptop
