When we leave home, we make sure that we’ve turned on our home alarm system. When the thieves trip any of the set up, the alarm will be activated with a loud intruder alarm noise hoping to scare the thieves off and also to get the attention of the neighbors. Some better alarm system can even call the defined phone number a few times or send text messages to inform that the alarm system has been tripped.

This kind of home alarm system has been invented many many years ago but for a computer, it is relatively something new. Imagine this, when you’re in a library and need to go to a nearby book shelf to get a book, you’d have to carry along your laptop. Or when you’re at work where people walk in and out, you need to take your laptop with you whenever you leave your work desk for a while.

What if I tell you that there is a way to set up a home alarm system on laptops?


Laptop Alarm will ring a loud alarm if someone will try to steal your laptop! When the laptop is disconnected from AC-power (someone pulls the AC adapter plug out) or someone removes or moves the USB mouse the alarm will go off. The best part is even if you’ve muted the volume, it is still capable of playing the annoying alarm noise!

Laptop Alarm will emit a LOUD ALARM on
1. Loss of AC Power
2. Shutdown / Log off
3. Unplug of USB Mouse
4. Mouse Movement

Other than that, Laptop Alarm is also capable of sending text messages via SMS to your cellphone in future version. Currently the beta version 2.0 is testing this new feature. All you need to do is check what would you like to monitor and click the Lock Computer button. You are then presented with a locked screen where you can enter your password.

It is important that you never plug a headphone in your laptop when you set the alarm! The sound generated by Laptop Alarm is very loud and may damage your ears. You should also set the sensitivity of the mouse movement to a higher number so that it doesn’t simply set the alarm when the mouse is being moved a little. Laptop Alarm is free, small in size and no installation required.

There’s another tool similar to Laptop Alarm called A.L.A.R.M. but with less features.

It silently sits in your system tray until you lock your workstation. If now somebody removes the A/C power connection to steal your laptop, A.L.A.R.M. will play a loud sound from your Laptop speakers until power is back again or you have unlocked your workstation. Of course, this is little protection from theft, but better than nothing if you have to leave your laptop or portable alone for a moment.
