If your laptop adapter is not warm to the touch and your laptop is no longer charging, your power adapter may have stopped working.
Laptops typically have a predetermined shelf life as destined by the computer gods. Of course, for the cash-conscious, there are many ways around spending much money. Especially when your laptop adapter is no longer working. Even if you think this would be the perfect opportunity to convince yourself or your provider to get you a new laptop. You still would need to resuscitate and retrieve some crucial data. Furthermore, there are many reasons not to upgrade if your computer was working fine all along. Of course, we are only assuming in the cases of those who think they should upgrade. Many would-be happy and wonder how will they find the part, especially when their laptop is old and a discontinued model.
Power cable or adapter
My laptop power adapter is not working
Your laptop adapter or charger cable as some would call it comes in two parts. On one end you only have the power cable and the second part is the adapter itself with the connector. And this connector connects to your charging point. If you happen to have a spare power cable, as shown in this image (shapes of connection and plugs may vary according to the model of your laptop), you are in luck. Try the old power cable, and if your laptop works well for you. Normal wear and tear could result in the copper inside the cable to snap and get disconnected. This is normal. If it is still not working, do not worry. Try and bring your laptop and adapter down to the nearest computer shop and get them to test if the cable is working. They would be more than happy to test it out for you and give it their recommendation. But what you are doing is merely honing on the real cause of the problem. If you are fortunate, they may have a similar compatible charger they can test.
