My Acer does this too. It's meant to; it tells you when the power has been disconnected. Did you perhaps have it muted in the three weeks before now?

You can turn it off by uninstalling the Beep driver - go to the Device Manager. Click the View option at the top, and make sure Show Hidden Devices is ticked. Then, go to Non-Plug and Play Drivers, right-click on Beep and uninstall it.

Keep in mind there's no way to undo this as far as I know.
