I'm trying to find out, once and for all, whether or not the Pc's we have support "vPro" functionality. We have a mix of HP 6000 Pro's, HP 5800's, and HP 4000 Pro's; with in that mixture, some Pc's have the "Intel Management Engine" installed (picture of icon included), while others don't; NONE of the Pc's w/o the icon are missing anything under "device manager". None of the CPU's in the PC's specifically say anything about "vPro"; they're just Intel Dual Core and Intel Core 2 Duo CPU's.
How do I know whether or not these PC's support Intel AMT and vPro? If they don't support it, why would some have the Intel Management Engine installed?
