    Watch Withings Scanwatch 2 (XNAHWA09) / No power

    Hy guys,
    This is my first post here 😁

    I've got my hands on a broken Scanwatch 2 (XNAHWA09) that I'd like to fix. The watch won't turn on.
    After removing the battery and connecting the watch to an external power source, I noticed that the watch was turning on sporadically.

    Upon visual inspection, I haven't found anything obvious except for this inductor, but maybe that's normal .

    I can't find any schematics for this watch except photos from this site:
