While in FaceTime in full screen I was disconnected with a message that I was now in a Power saver mode.
My lap top was plugged in at the time.
I could not disable this mode.
What can I do to correct this function in the future?

Navigate to "System Preferences" as follows: Apple icon in the menu bar at the top left of the screen -->«System Preferences»-->type in the word "power". The appropriate preference will be brightened up against the dimmed area of the rest of preferences in the preferences window. Click on it. If the option "Put hard disks to sleep when possible" is selected then deselect it.
