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.

Thanks for the detailed info Raymond.
thanx.. good advice.. but about the mouse sensitivity, shouldn’t you set the mouse sensitivity to low, so that if you move the mouse a little, there’s no response…. because if mouse sensitivity is high..even a touch can move the cursor and trigger the alarm..
That’s right hardik. We usually say set the mouse sensitivity to low so it won’t be so sensitive. But for this Laptop Alarm, you’ll have to set a higher number for it to be less sensitive.
that is interesting. Im just afraid the thief will destroy the laptop instead. ^^
Nice tip !
I would try it, but I usually don’t take the laptop to public places and therefore if they steal on the car will be turn off.
Does the alarm go off every time you return to your laptop ?
Could a thief just plug in a set of headphones to mute the alarm ?
@IanG: That’s a good idea. When you plug in a set of headphone, the alarm’s volume will be much lower. By the way, usually laptop thief wouldn’t know you have that alarm software installed. Like I mentioned at the end of the article, this is little protection from theft, but better than nothing if you have to leave your laptop or portable alone for a moment.
Yes it is a lot better than no protection at all. And it would very presumptions of a thief to carry around a set of headphones.
this is good.. thankz ray..
Macs also have a security app that implements the functionality of their built-in sudden motion sensors. It’s called iAlertU. The alarm can be set using the remote, just like your normal car alarm, which I think kind of handy and pretty cool. When the alarm were triggered, you can set the iSight camera to take image on the event of trigger and email it to you directly.
thieves, do not read the blog raymond, but I tried this program, he bug, after the fact, it sounds more!
this is not really useful …
