i have never heard anything like that with my libra, and I am hyper critical/sensitive of hum, buzz etc, and I read in a quiet room.
I recall owning a PC monitor ( LCD) where i could hear a faint buzz that went away only if brightness was set to 100%, so if the Libra uses a pulse method to reduce brightness, may its to to with that ?.
folks here are saying coil whine but are there even any coils inside, I associate coils with power supplies, transformers, graphics cards none of which are inside of a Kobo ?
"Just about anything with a power source can create coil whine to some degree, but it's usually caused by an electrical current going through a power-regulating component like a transformer or inductor, causing its electrical wiring to vibrate at a variable frequency."
