I've only noticed this today, but I normally have music/something playing on my speakers so I probably wouldn't have heard it before.
It's not like SUPER loud, in fact it's pretty much inaudible unless I put my ear up to the charger, I only noticed it when I leaned over it to pick something that had fallen up.
I'm just wanting to check that this is fine? I did read a comment somewhere else that said unless it was super loud it's fine, but I mean it's always best to be on the safe side right?
I've had a few problems with my laptop before, specifically it not charging, and then another point where the screen failed to show things?
But yeah anyways my laptop is a Samsung, and the charger is just the one that came with it when I bought it.
