Common problems and solutions of laptop power adapter light not working

The laptop power adapter is one of the important components of a computer, providing a stable power supply for the laptop. However, sometimes we may encounter issues where the laptop power adapter light is not on, which may cause confusion and concern. This article will introduce common reasons that may cause the laptop power adapter light to not light up, and provide solutions for you.

1. Damaged power adapter:
①Check if the adapter is plugged into the power socket: First, ensure that the adapter is correctly plugged into the power socket and that the socket is functioning properly.
②Check if the power cord is intact: rule out whether the adapter power cord is damaged, as damaged wires may cause the adapter light to not light up. Try connecting using a different power cord and check if the light is on.
③Check if the adapter is damaged: If both of the above are correct, it is highly likely that the adapter itself is damaged. You can try using another adapter for testing. If the light on the new adapter lights up, you need to replace the damaged adapter.

2. Power socket issue:
①Check the laptop power socket: Sometimes the metal contacts of the power socket may not light up due to poor contact. Try gently cleaning the power socket and using a small tool to slightly bend the contacts to improve contact.
② Check the wiring connection of the power socket: The wiring connection between the power socket and the motherboard may be loose or disconnected. With the guidance of a professional, you can turn on the computer and check the wiring connection of the power socket.

3. Power management settings issue:
Sometimes the power management settings of the computer may affect the brightness or working status of the adapter lights.

① Check power management settings: Enter the computer's settings interface and ensure that the power management mode is correctly set to "High Performance" or "Do not switch mode when inserting power" to ensure that the adapter is working properly.
② Update computer driver: Check if the driver of the laptop is outdated, and updating the relevant driver in a timely manner may help solve the problem of the adapter light not turning on.

The laptop power adapter light may not light up due to various reasons, including damaged adapters, power socket issues, or power management settings issues. By checking the status of the adapter and power socket, as well as adjusting power management settings, you are expected to solve this problem. If the problem persists, it is recommended to consult a professional or contact after-sales service for more detailed assistance and support.
