Try the same cord on an identical laptop (which might not be easy to find, granted). Wiggle the laptop - as if you were using it the way you do now.

Then try THAT person's power supply cord in your laptop. See where the failure. Could be both ends.

I replaced the cord about 6 months ago because I had a cord problem, but that one had an obvious short (could smell the electrical burn) that's why I'm not sure if I am having cord or jack problems. I know that is not the problem with this cord. I seem to have to twist it just right to get it to work and then when I breathe it moves and I lose power. What is the normal life of these cords?
