Subject: Breaking LoJack for Laptops

Let me begin with your very very WRONG. Those laptops cant be hacked even
with the password.
Have you lost what little mind you have left? Thats like saying there isnt a
local for * 2.6.x stolen from lorians /home , give me a break. Go audit
linksys router manual on typo's or something.
And merry xmas !Z
