ebay dell laptop power cord

Why is my Dell laptop power cord no longer works?
The original cable provided with my laptop Dell has begun to decay and showing exposed wires and finally stopped working, so I bought a new one. After a few months has started the same thing happens to it; too. So I bought another and found it would not work at all, if I connected hard and stood firm with his hand, so I thought I was bad and an adapter cable .. Then I bought another on eBay. The same thing happened with that. Finally, I broke down and spent $ 60 on a real "Dell and are not going to work well, unless holding the rope in hand, do not let go. The battery will not charge. It's very frustrating and I think that buying a new laptop. Is there a way to solve this problem at all? As someone told me to replace the connector – How is that done?
that is the AC plug into the laptop. Connectors cost between $ 6.00 – $ 25.00 The portable computer must be open and desolder the old connector and removed, and the new soldiers in. This is not an easy task. Suggest considered shop. Furthermore, it is not uncommon in laptops over 2 years. Probably searching for parts and labor from 75.00 to 125.00
