Re: Aspire R15; can the machine be physically locked? I see no input for a lock, pls advise, thanks!

I thought a Kensington lock might work, but it doesn't.  I went back to the store I bought it from and asked what lock to purchase and they said they didn't know of any for that laptop.  Is it correct that this model cannot be locked with a physical lock?  I can't imagine that's right.  Any help would be greatly appreciated.
