Is there a point to using theft tracking software like Prey on my laptop, if you have login security?
Your "problem" is that your machine is secured too well.
Theft tracking software counts on the thief being able to use your machine, at least a short amount of time. If you use BIOS passwords etc., there's just no way to do that -- you'll get very little value out of any such software.
I use a theft tracking software on my Mac OS X laptop.
My personal home directory with all my data is encrypted and my user account password protected, and I've made sure to create a few (low-privilege) user accounts with very weak passwords (mostly clean accounts I use e.g. for doing presentations), as well as activated the guest account.
They can't access my data, but I want them to use my machine e.g. for web browsing! Only with network access, theft tracking will work, and I'll have a chance at being able to recover my machine.
Any thief that steals your laptop won't know that it is secure until after they have stolen it, which means they will either go to the effort of breaking in or bin it, either way you lose.
I installed Computrace (Lo-Jack) on my daughter's laptop when she went to uni. It lives in the BIOS which means it re-installs itself even if the disk is reformatted, it also OS independant. It's not free.
Also, you have the ability to remotely wipe your drives.
I am not able to recommend any particular software for your laptop, however:
(From http://preyproject.com/) "allows you to gather information regarding the device's location..."
Password protection is not enough to be able to track down where your laptop has gotten to.
If your laptop doesn't boot in the first place (Locked by BIOS requiring a fingerprint scan) so that tracking software does not run will mean that it is of no value anyway.
The other thing to consider is that your laptop hard drive can be removed and plugged into another machine - so if you are worried about your data not being accessed by others then you should look into Whole Disk Encryption which you can get with PGP or TrueCrypt)
