What it does
You're working in a café. You need the bathroom. You don't want to pack up your whole setup — but leaving a laptop unattended is how laptops disappear.
Arm LaptopAlarm with a double-click. Now if a thief yanks the power cable to grab your laptop and run, it instantly blasts a piercing siren at full volume through the laptop's own speakers. Heads turn, the thief panics, and your hardware stays yours.
How it works
Unplug the charger → alarm fires
The moment the power adapter is disconnected, the siren sounds and keeps going until power is restored or you disarm it.
It forces maximum volume
Even if your laptop was muted or turned down, the alarm cranks the system volume to 100% and unmutes it so the siren is genuinely loud.
Headphones can't silence it
On Bluetooth earbuds or wired headphones? The alarm reroutes sound back to the built-in laptop speakers — so the whole room hears it, not just the thief.
