Time for a new power supply. They are sealed and not intended for servicing.
Also surprised at the shock as for voltages are usually around 19VDC which doesnt shock most. I think the most shocking part about it might have been the spark that would make one jump at the surprise of it not expecting it etc.
My daughter when she was about 3 years old put tweezers into a 120VAC outlet in our bathroom and she was very fortunate that the GFI outlet popped. While the GFI outlet popped it did happen to vaporize part of one end of the tweezers before popping leaving sharp edge of tweezer a rounded ball of metal. This pitted the GFI outlet contact and I had to replace it because plugs were going in hard past a pitted bur contact inside. I asked her what she was thinking and she didnt know why she did it.
When I was about 5 or 6 I found what I thought were some interesting light bulbs in the basement. I screwed one into the livingroom lamp and turned the switch on and the lamp died. It was one of the older screw in type fuses for a fuse panel which share the same socket as a light bulb. The Lamp was the weak link between the 14 GA wiring in the home and the 15 AMP fuse in the fuse box and the 15 AMP fuse I screwed into the lamp. It did blow the 15 Amp fuse in the fuse box for the living room but not before turning lamp cord into a heating element inside making a very lovely melted plastic smell. I was asked why I did this, I said I thought they were light bulbs they have the same screw in socket and glass top and you look in and see the filament which its a fuse not a light bulb but I didnt know better at age 5 or 6. I had a fascination with electricity and light bulbs as a young child and shocked myself many times, and luckily didnt burn my parents house down or kill myself in the process.
