Have you noticed that the laptop power adapter (charger) occasionally makes a slight current sound when charging the laptop? Don’t panic—this is actually a normal phenomenon!
If the sound bothers you, here are a few simple fixes you can try:
① Disconnect and reconnect the docking station from your laptop;
② Insert an additional USB flash drive on the docking station or unplug a USB flash drive;
③ Ensure proper ventilation around your adapter to prevent overheating.
In most cases, this slight electric current sound may disappear naturally. However, if the noise becomes excessively loud or persistent, it might be worth checking your hardware for defects.
