Laptop lock

I have one of those laptop locks that fit into the docking station and prevent the laptop from being undocked.
It has 4 revolving digits and one combination that works. Yeah right as if I'm going to tell you that its "hunter2".

What I wanted to know was how much time will it take to try each and every combination.
There are a total of 10000 combinations. To go from 0000 to 0040 took me 3 minutes - including initial reset to 0000.
That means 750 minutes for the whole range = 12 hours in the worst case using nothing but brute force.

This basically means that your laptop can be stolen over the weekend, even if it is locked.
It also means that any thief who has repeated access to your lock is going to break it within a maximum two nights.

So much for security.

Personal best is under 5 minutes. but Personal Average in unlocking such number locks is about 30 minutes. in a weekend, i will release plenty of laptops... watch them on ebay on monday! just kidding, I have ethics. :P

why would I bother unlocking it when I can cut the wire and still it together with the dock?

I guess cutting the wire is much simpler. So much for the illusion of security
