The computer's power adapter has a slight current sound.

Issue Time:2006-10-11
It is normal for the power adapter to make a sound when it is powered on; if the sound of the transformer is not very low, it is generally not power; it may be that the quality of the transformer is slightly inferior and does not affect the use; the key is to see the sound Because the voltage and current need to be converted in the power adapter; there will be a ballast working when it is energized, so it will make a weak sound; if the power adapter makes a loud sound, then you need to check the cause carefully.
