Does the Dell Vostro 15 7510 have a slot for a security lock cable?

Hi,​

​I've had my Dell Vostro 15" 7510 laptop for a number of years, and I am going on a trip and wanted to use a security lock cable while I am away.​

​I could have sworn that I bought and used a security lock cable (with keys) for it several years ago, and I've found several lock cables that I have, but am not sure if they were for the Vostro, and I was also looking at the Vostro today, and I can't find a slot for a security lock cable on it???​

​So does the Dell Vostro 15 7510 even have a slot to attach to security lock cable?​

​I did find this document:​

​https://dl.dell.com/topicspdf/vostro-15-7510-laptop_owners-manual_en-us.pdf​

​and in Table 7 "External Ports" in that document it says:​

​Security-cable slot None ​

​So now, I am wondering if I am IMAGINING that I purchased such a cable?​

​Can someone tell me if the Dell Vostro 15 7510 can attach to a security lock cable, and if so, point me to where I might buy one?​

​Thanks,​

​Jim​
