A.L.A.R.M. is a software that runs in the background until you lock your workstation. If your laptop gets stolen by someone removing the A/C power connection, A.L.A.R.M. will play a loud sound from your speakers until power is restored.

What's great about A.L.A.R.M. is that you can use any media file as the alarm sound. The software supports all major file formats, so you can choose your favorite song or an attention-grabbing sound effect. If you don't have anything in mind, there's already a brilliant alarm siren included.
Lastly, it's worth noting that A.L.A.R.M. is a free open-source software that's released under GPL. This means that you can use it without cost and even access its source code if you're interested in tinkering with it.
