Unfortunately laptop tracking software is like car insurance, compensation isn't free, but fortunately, it isn't as expensive. First you need to do several things before you buy any software. First call your laptop manufacturer's tech support as ask them if your laptop have Absolute Software's Computrace BIOS. This built in several manufacturer's computers features a chip that allows you to locate your laptop even if the thief has reinstalled the OS or changed the hard drive.
Even if your computer does not have the chip, you can still get the protection. The software available in purchases from select retailers in 1 year, 2 year, and 3 year licenses or online at www.lojackforlaptops.com.
If you go CompUSA, they have a $20 rebate now before the end of the month (Aug.). And if you bought your laptop within the last 3 months, you will entitled to the an additional $10.
Enough with rebates, but with the money you save, I advise you to also purchase a Kensington security lock. This locks your computer to an unmovable object, much like a bike chain, but instead of looping around a wheel, you insert the T-bar into the security slot on your computer and lock your computer.
Basically, my advice is but the software Computrace Lojack for Laptops.
Don't buy the Crossing Guard crap and definitely ignore what the other guy is saying. The lojack software has been proven to work.
