Hello there, I'd like to ask for help. I own a Twinhead laptop. Lately, when I charge my laptop and use it at the same time, it will make this tiny noise from within the laptop. Like a ''bzzzttt bzzzzttt'' noise. A very tiny one but I can still hear it clearly and it's kinda annoying. It's making the sound most of the time. Especially when I'm surfing the net. But when I discharge my laptop,it won't make the noise anymore. What does it mean? Before, I 've never heard this noise before. I swear!
