We have some Dell 7040 mini desktop that are provision with Vpro via USB sticks. They are mounted to our ceiling tvs and are use for displaying videos. I recently notice that i lost KVM control of those machines and i can no long vpro into them. The only solution i found so far is to go into the IntelMBex Bios to disable and enable KVM. Once i do that they work fine again, this has happen to me twice in the last couple of months.
