This morning I went to charge my laptop because it has run out of battery. When I plugged my charger in, I noticed the light that signals it is charging did not even turn on. I started to inspect the charger and I was looking at the small piece that actually plugs into the charger. There are fours small gold covered prongs that connect to the port in the laptop. I noticed one of these prongs was missing it's gold covering and was exposed.Could this be the reason the charger no longer works? I only bought the charger two months ago and do not want to pay 80 dollars for a new one. Is there a way to remedy this?
