Wrap your charger's exposed wiring with electrical tape before proceeding. This will help to prevent any kind of electrical hazard or further damage.
Push the wire next to the charger base (the connecting tip near the laptop end) side to side to see if you can get a current to connect. This is a temporary solution, but it can help you salvage your files so that you can work with them on a different computer.
Make sure that it isn't a battery problem. Many laptop owners believe their charger is the problem when their battery is charging. Laptop batteries generally begin to lose the ability to hold a charge after two to three years of heavy usage. Try removing your laptop battery. If the computer still runs, the charger is not the problem.
Check to see if the issue lies in your computer. You can do this by testing out an alternate charger on the laptop--if the charger still does not work, it's an internal laptop issue. For this kind of power system problem, you will probably have to send your computer to its manufacturer rather than a local repair shop.
Replace your charger. A replacement charger is usually easy to find and quite affordable. Instead of going to a local electronics retailer where universal chargers can cost $100 or more, look online for your specific model's charger. Some chargers can be purchased for as little as $5
