I have a question if I may. We recently purchased a couple of Surface Pro at our business, at 2 and a 3. They are both using docks. They are also on domains and are running 8.1. My question is this. When the user locks his computer and gets up to leave, after a few moments, the computer goes offline. I have tried setting the power settings so that it is using max performance and turning off sleep mode but it does it anyway. It happens after just a minute of them being gone. Anybody have any suggestions? Thanks in advance!
