Any way to turn off the screen (manually)? Holding power button will only shut it down. Not interested in the various time out settings...instead is there a way I can force it to sleep/turn off display?
The short answer is no. The concept of the device is to use it in common areas, especially meeting rooms where if needed, you can shut down the device when not in use to save power, or change the power settings so that it will be ready for the next user.
