Alienware 15 Noble Lock Port Question

Ok So I am only familiar with Kensington lock ports. I assumed this had a Kensington lock port and bought a Kensington. To my disappointment It wouldn't fit. At first I actually thought maybe the port was damaged and even tried to force it. (hope I didn't break anything).
Then I discovered online that this is not a Kensington but it is a "Noble lock port".
However these types of ports lack info online. I found their site but they seem to have different types of locks and it doesn't really say which ones are compatible with this computer.

Does anyone have any info on this?

I was looking to get a combination lock similar to this but want to find one that is 100% compatible.

This one should work.

 

I appreciate the quick reply. However I am looking for a combination lock. Can you confirm or deny whether the first one I posted will work? Its a Noble lock. I was hoping it would. It seems that switching to noble ports has caused some issues as Kengsingtons are so widely available and noble locks are confusing as to which are compatible.

 

The one you linked above doesn't say it's compatible with Alienware. However, we have some of those down here and they look exactly the same. They should be compatible.

Did you try checking on the DELL website?
