I've been noticing a strange reproducible issue that does not seem to, as yet, have been reported here. When cold booting the SurfacePro 3 (SP3) in the dock, CPU utilization creeps up, when idle, to around 28%-30% with no apparent cause. The utilization is by System and System Interrupt processes according to the task manager. I've been able to reproduce this daily, and it does not occur when the device is started outside of the dock. I can also stop this utilization issue by undocking the device hot (while running) and re-docking. You can actually have the task manager running at the time and watch these two processes stop eating the CPU when you do this. Does anyone have any idea why this is happening or is this occurring to others?
