Chromebooks run Google's ChromeOS and are widely used in schools and workplaces, so their start-up and shutdown tones are familiar to millions of daily users. That everyday recognition helped the power-down chime move from a plain system sound into online edits, where it works as shorthand for quitting, crashing or being switched off. Unlike dramatic error noises, it stays calm and polite, which makes the contrast funnier when it follows chaos. It remains popular for short tech, school and gaming clips where a quiet, final sign-off says more than a loud effect.
