Before you make a decision about the next step, maybe you would like to know why the laptop charger is not working. Here are some commonly found reasons for this problem.
You have been using the wrong laptop charger for your machine, or someone else has been using your laptop charger for another machine. This may seem like a harmless act, but it affects the battery on your laptop, and charger you are using as well.
Your laptop battery has become weak and worn out from excessive use. Due to this the battery is not charging at all (or charging very slowly) when you plug in the charger. In this case there is absolutely nothing wrong with the charger itself.
The wire of the laptop charger has got a distinct curve at one point, and this is restricting it from transmitting power. You need to look out for such bends in the wire, as this will ruin the efficiency of the charger in no time.
This may sound elemental and stupid to some, but it does happen to many people. Maybe you are simply using the wrong laptop charger by mistake, or maybe you have failed to switch on the power switch. Check both these things to be sure.
Any of these potential causes could be the reason behind your laptop charger not working. As a result of these, either the mains power lead of your charger may be damaged, or the power supply unit may be damaged, or maybe the lead itself is damaged or broken somewhere, or some circuitry inside the laptop is damaged, and not responding to the charger. It's hard to accurately tell which of these problems could be the real cause of your laptop battery not charging, without physically examining the machine.
