If i'm plugged in with my ac adapter, and the battery is not charging, the AC adapter gives off this high pitched noise. it's not extremely loud, but it's enough to give me a headache while using my laptop. The only time it doesn't make the noise when the battery is not charging is when i'm doing something more cpu/gpu intensive, like gaming. Is this a defect that I should get replaced, or is it normal?
