Everyone is no stranger to laptops. Many people use it in their daily work. But many people will find that the laptop has current noise when using it. This phenomenon has caused many people to worry about the life of the laptop and the unexpected situations encountered during use. Many people do not know how to solve this problem. Here is an analysis of the cause of the current noise of the laptop and how to solve it.

Ⅰ. Check the quality of the computer microphone. In general, the quality of the microphone of computer is uneven. Poor quality will result in current noise. First, check whether the current noise is generated by the headset. Check if there is any damage to the headset. Test it by changing to a new headset.

Ⅱ. Set up the laptop. If there is no problem with the headset itself, it is likely that there is a problem with the computer system settings. Click the sound icon in the lower right corner of the taskbar. Right-click to select the Recording Device. Find the Microphone option and click Properties. Find Enhancement in the tab. You can check the Noise Suppression and Echo Cancellation options. Then lower the emphasis on the microphone under the sound card level. And right-click the sound icon in the sound task bar, select the Sound. In the Recording options above, disable all devices except the Microphone.

Ⅲ. If the above steps do not eliminate the current noise, you can observe whether there are other electronic devices around the computer. Electronic products such as mobile phones. Because they all receive messages and calls. This will interfere with the laptop on the side. Keep it away. Furthermore, you can check the driver of the laptop. If the sound card driver is damaged, the microphone will also produce current noise.

Ⅳ. The hardware is damaged. If the laptop is used for a long time, the internal storage is nearly full. Due to the operation of the computer, some current noises will be produced. If the internal hardware is damaged, a louder current noise will be produced. So, when analyzing the current noise of the laptop, it is necessary to do a good job in the self-test of the laptop. Then eliminate the causes of current noise one by one.

Ⅴ. If the laptop is left unused for a long time, some current noise will still be produced. Because the laptop has not been turned on for a long time. If it is turned on suddenly, it will occasionally produce current noise. It needs to run for a while, and then to observe the effect. If there is always current noise, it is necessary to detect the cause of the fault.

The above is the reason and solution of the current in the laptop. If the current noise cannot be solved, the laptop needs to be sent to the after-sales service station for testing and processing. By analyzing and processing the causes one by one, the current noise will definitely disappear.
