Morphology
The meaning 'to depend on' is not directly derivable from the literal senses 'turn' (to change) and 'on' (active/powered), so a B1 learner who knows the constituents would likely not predict this sense. There is a loose, somewhat metaphorical link (turn + on/upon → be determined by), but the particle usage is idiomatic and less frequent, making the expression only partially transparent.
Etymology
Turn on here is like flipping a switch to start showing a quality, as if you can turn your charm or tears on when you need them. That's why it means 'to produce or display a quality suddenly or on purpose'.
