1、 The reason for the noise of the power adapter

Power load issue: When the power adapter operates under overload, it may emit a sizzling sound due to overheating or excessive loss of internal components. In addition, under no-load or light load conditions, the transformer of the power adapter may also emit abnormal sounds due to oscillation phenomena.
Process issues: The power adapter may produce abnormal noises due to loose wire wrapping, air gaps in the magnetic core combination, inadequate paint immersion and drying, or unsuitable air gap length.
Aging and damage: With the increase of usage time, the components inside the power adapter may age or be damaged, which is also a common cause of noise.
2、 Solution to the sizzling sound of power adapters

Replacing the power adapter: If the power adapter has been used for a long time and often makes a sizzling sound, replacing it with a new power adapter may be the most direct solution. The new power adapter has undergone scientific design and safety testing, which can provide more stable and efficient power output while reducing the occurrence of abnormal noises.
Cleaning the power adapter: Excessive dust or other debris inside the power adapter may also cause a sizzling sound. At this point, we can disassemble the power adapter, clean it with professional tools, and then reassemble it.
Check the power cord: Sometimes the power cord of the power adapter may become tangled due to being dropped or pinched, resulting in abnormal noise. Check if there is any voltage loss in the power cord, and if necessary, disconnect the coil to effectively reduce abnormal noise.
Lowering working temperature: Prolonged high load use can cause the power adapter to heat up, resulting in a sizzling sound. We can reduce the load on the computer or provide sufficient ventilation for the power adapter during use to lower its operating temperature.
Check and adjust the power load: Excessive power load is also a possible cause of the power adapter making a sizzling noise. We can adjust the power load of the adapter by checking for grounding issues in electrical appliances, reducing the number of times high-power appliances such as air conditioning are turned on, and other methods.
3、 Summary

The noise from the power adapter does not necessarily indicate a serious problem, but it cannot be completely ignored. When encountering such a situation, we should first determine the size and frequency of the sound, and evaluate the condition of the power adapter in conjunction with other abnormal phenomena such as overheating, smoking, etc. If the sound is too loud or accompanied by other abnormal phenomena, it should be stopped immediately and professional repair or replacement with a new power adapter should be sought. At the same time, we should also regularly inspect and maintain the power adapter to ensure its normal operation, extend its service life, and ensure our electrical safety.
