Death of a Laptop Power Supply

This week my laptop's power supply finally died. It had been dying for quite some time now, as evidenced by the pictures below, but now it is dead. No fun little sparks jumping the gaps between bare copper wires. No power indicator lights. Nothing.

Here's a picture of the power cable going into the power supply. Notice the copper!



Here's a picture of the power cable coming out of the power supply. Notice the shiny wires!



And, lastly, a picture of the laptop. Without power. Dark and silent.
