Im sure it has one!
But, be warned....
A member of this very forum had a video spread like wild fire on the net and news channels showing how insecure the locks are, bypassing it with a toilet paper roll and a ball point pen!!!
Also Ive read articles saying the usage of one is pointless because if someone really wants your laptop its just a hard tug away#1 and even when they cant tugg it off usually damage it very badly in the attempt!
point being although it has a lock, they are hardly effective in theft prevention but and generally only work as a deterrent for a thief to grab one w/o. That being said 2 dell's side by side, one w/ a lock and one w/o the thief will go for the unlocked one usually(if not both)
But an AW w/ lock next to a Dull w/o one is hardly a deterrent. Ask youself this, If you are a car thief and have a choice for a lamborghini or a honda the only difference is that the doors onthe lambo are locked, are you really gunna go after the honda?
All that said, to say this, the locks wont stop someone who wants your laptop! So dont let it out ofyour site!
