Software: Laptop Alarm (Laptop Security)

Laptop Alarm is a free program that can help protect your laptop from being stolen in a public area such as a coffee shop or library when you're away from it. If someone tries to still your computer it will sound an alarm.

Its a fairly simple program to install and use. All you need to do is download and run it. Select the events to respond to, and press the Options button to set a password. Then press the Lock Computer button to protect your laptop.

Note: This program is only a deterrent, and can't protect against all types of theft. The program can only respond to a few types of events (such as AC power loss, mouse movement, etc.)
