Can you provide me the processor you have in your DELL 7520?
Sorry for the delay I was away. Thank you for your reply: the processor is Intel Xeon v.6 1505 quad-core, kaby lake.
i've been able to validate that the processor is vPro enabled. To access MEBx, it's usually by doing CTRL-P at startup, however with Dell's, sometimes they are in the startup menu (accessed by F12 at startup). Also, in BIOS there is an option to "hide" the MEBx CTRL-P.
Because the OEM's customize these details and because we are unsure of the configuration of your 7520, Dell would be your best resource for these questions.
