Solved! Adapter concern issue

[Adam_200]

So my laptop charger has this sort of whistling/buzzing sound when I put my ear on it. However, when I plug it into the laptop it stops completely.
What's the issue there?

That's probably the buzz from the transformer inside (depending on the age of you charger) but it doesn't indicate that it's gonna die soon.

So I just bought an ac adapter for my laptop, plugged it in. When I listen really carefully I can hear a tiny buzzing inside the adapter. Is this normal? Everything is clean and the adapter is genuine.
