WD19

Hi, I have a brand new WD19 docking station. It works fine, but as soon as the laptop battery (whichever laptop it is) is fully charged it starts making a strange and really annoying noise. Has anyone had the same problem? Any suggestion?

    I never overcharge the battery, if I have to disconnect from the docking station every time the battery is at 100% it's kinda annoying.

    @pgrign  Sounds like coil whine.  It's annoying, and I don't know exactly what electrical components or properties cause it, but I've seen it happen.  I've noticed that some laptops make a high-pitched noise when I'm scrolling content on the display quickly, for example.
