So my brother's rabbit bit off the connector to usb fan. He tried to fix it but apparently it just shuts off the laptop when he connects it. This is what he brought me, any Ideas what to do?

also, the two wires (black and red) seem to be almost "glued" together, do you think there could be a short circuit?

Possibly. It looks like he pulled them out and shoved them back in the connector, but he did it backwards.

The red wire should go to the post that's in the + side on the back. It looks like its backwards in your pic.

I would probably take the connector off and remove it from the board. Then just solder the wires directly to the board.
I think I would also tape the whole thing to the usb plug because there's not a useful amount of wire left and it's just going to break something dangling.

In b4 someone jokes about eating your brothers pet. Because hurr hurr rabbits

Polarity is wrong on the input (from the USB) VCC is positive (red) and GND or ground (black) is negative, just swap them over your pic shows its reversed. (rotate input 180 degrees)

One time I think I shorted my usb port (or may have shorted the 5v line with a data line....) and my USB ports and headphone jack stopped working. Must have just triggered a protection circuit because it was fine when I rebooted it.
