Morphology

put + to + sleep

The meaning 'place into a low-power or inactive state' is directly derivable from combining 'put' (bring something into a state) with 'sleep' (a state of inactivity/rest) and fits the common English pattern 'put X to Y' meaning 'cause X to enter Y'. Although the phrase can have a different idiomatic sense (e.g., euthanasia) in other contexts, the device-related sense is a straightforward metaphorical extension of the literal constituents and would be understandable to a B1 learner who knows the words.

Etymology

Put to sleep in medicine comes from the picture of a doctor giving medicine that makes a patient sleep before an operation so they feel nothing. That's why the phrase can mean 'to make someone unconscious for a medical procedure' and is also used to say 'to try to stop thinking about painful memories'.
