1. Start by clicking the windows icon (Start Menu) on the bottom left of the desktop.
2. Next, just start typing ‘Power Options’ and click 'Power & Sleep Settings' to open.
3. Be sure ‘Never’ appears in both drop down menus under 'Screen' and 'Sleep'.
Under 'Shutdown Settings', you will want to make sure that all check boxes are UNCHECKED, please do not check any of the boxes.
This will allow you to be able to press and hold the power button on the front of the panel until a message appears to close and shutdown. Select OK (or wait for the 10 second countdown) and the panel will begin to shut down windows as well as power itself off. The power light will flash, but once it is a steady red, the PC and panel should be powered off.
