![]() ![]() If your computer does turn on, your power cord is the problem and you should replace it.Īlso, you can check the same power cord on another computer, or other device that requires the same power cord type and are working properly. Try plugging a different power cord in a power outlet which is working properly. Maybe the power cord doesn't have visible signs of damage. If the power cable is damaged (e.g you saw a blue, yellow-green or black wire, or copper), replace it. Unplug the power cord (the cord which connects the computer's power supply and the power outlet, or the cord that connects the laptop's adapter and the power outlet) and examine it carefully. As time goes by, the power cord weakens and it doesn't provide a good flow of electricity between the power outlet and the computer.
