I wonder if some cases can't be fixed by some epoxy..

  Epoxy? I have read that opening the laptop and putting superglue on the right parts might reduce the noise.

    Yeah, do that and you may cause the power converter to overheat and die because the superglued inductor may not get enough airflow over it anymore. These wonderful "fixes" (along with people "reflowing" stuff using heat guns) are a great way how to turn an annoyance into an expensive to fix failure.

      Heat dissipation in an inductor should be small - if it's significant the Q of whatever power converter its in will be bad.

  This is the correct answer; or hot glue if you want a more reversible solution. Might be a little tricky to identify the whining component. Perhaps a mobile app dB meter waved around will pinpoint it.

    Would superglue also work?
    • pjc50 4y ago
      I would assume so, and some googling reports success with this. You just need a small amount, enough to wick inside the coils themselves and lock them in position.
