Hi, everyone - I have a dell e4300 - actually I have three. On one, when it is plugged in to charge, the blue light that indicates that it is plugged in and charging, which normally would be blue continuously, is blinking, or oscillatiing, off and on. I bent the pin on the inside of the cord slightly in order to maybe get a better contact, and bent the barrel slightly for same reason - the blinking is the same. So, it does not quite seem like this is a weak, variable connection. Also, I get the same thing with another charger cable. Does this mean something?
