    Probably a loose coil on an inductor. Nothing to really worry about other than the annoyance of the sound.

    Well, I can't be 100% certain since I can't hear it myself, but it's something I've heard a few times before and know the cause. Assuming that's what it really is, then it's not something that will effect any function of the laptop.

    The charging circuit probably switches from a high current charge rate to a low current charge rate. The power inductor that's making the noise isn't working as hard, so the noise stops.
