On your Chromebook, click the status area in the lower right corner to display the quick settings panel. Select the gear icon to open your Chromebook’s settings menu.

At the bottom of this page, find the “Play sound at startup” option and enable it.
If you’re having trouble reaching this exact menu, you can look up the name of the option in the search bar at the top of the Settings menu.
That’s about it. Now your Chromebook will play a short startup chime on the login screen when you start it up after completely shut down. However, keep in mind that it won’t ring when you just wake it from sleep.
The chime volume depends on the audio levels of your Chromebook. To mute the sound or make it less obtrusive, just turn down the volume on your Chromebook speaker before shutting down the computer.
Alternatively, using the Chrome extension Startup Sound for Chromebook, you can also set the startup sounds of other operating systems such as macOS and even Windows XP.
Once you’ve installed it, click on the icon in the extension drawer at the top right corner of Google Chrome.
Choose a startup sound from the drop-down list and click ‘Save’.
Unlike Chrome OS’s built-in startup chime, this extension’s chime will be triggered as soon as you log into your Chromebook.
