I have a number of activities configured, two of which use a HTPC, and would like a bit of advice on setting the power states of the HTPC. I would like the HTPC to remain on whilst I view other activities (that don't use the HTPC) like plain "Watch TV" but I'd like the HTPC to be turned off once I press the power button (top left corner) to end an activity. So here is a scenario. I want the HTPC to turn on when I specifically switch or start one of the two HTPC activities otherwise it remains off. However, once turned on HTPC should then remain on until I end an activity with the power button. How do I set that up?
