    Just like the title says, my MBP's power adapter is quite hot and makes an audible humming/buzzing sound. It has also, now and then, had the 'battery not charging' dim indicator light issue.

    So, should I have it replaced before it erupts into flame (or fries my computer), or is it normal behaviour?

    If you can make them exchange it for you, then try. I have a MB, and my charger was also like that. It hummed and was always extremely hot. So hot that the connection of the small cord with the charger started to melt (not melt literally, but do became very fragile to the point it simply broke).

    So I went to my Apple Store and the guy there gave me a replacement. Later on I noticed this charger was for a MBP. Now the charger is never "too hot", only warm.
    It still makes a little sound, but nothing compared to my last charger.

    EDIT: As for your question if it is normal. Yes, I would that it is pretty common that Mac charger behave like that. No need to worry, but it seems that not all charger behave like that.
