I was recently browsing through some email of mine and found a tech tip on how to reuse an old USB key. Many of us have bought bigger and better USB keys as technology has allowed these devices to hold larger amounts of storage while reducing its size.

If you have an old USB key around and want to protect your laptop (or even desktop for that matter, I suggest you try the given program below and add a bit more physical security to your laptop. It’s perfect for protection in dorm rooms, offices or anywhere you’d like to beef up some security on your machines.

Don’t throw your old USB flash drive away. Instead, you can use an old flash drive as a laptop alarm to prevent your laptop from being stolen. Here is how:

1. Install free software on your laptop. www.lalarm.com/LaptopAlarm. (free for personal use)

2. Fasten a neck strap to your old USB flash drive.

3. Fasten the other end of the strap to a table.

4. Plug in the USB flash drive into a USB port of a laptop.

5. Lock the laptop by pressing the Windows logo key and L key together.

When a thief removes the laptop from the table, the USB flash drive will be disconnected from the laptop and then a loud siren sound will be emitted. (See photos: www.lalarm.com/arm2) In addition to sounding an alarm, the software sends an alert to your mobile phone. This tip is also useful if you worry about identity theft. The free software destroys data in case of laptop theft.

I have not tried this software, nor do I suggest trying it blindly on a laptop that has crucial information on it before you are 100% familiar with the software and understand its features and functionality.

If you have some luck and find it useful, let us know!
