There are two different notification messages that can be displayed to the user: Warning Popups and the Notification area.
Prior to turning off a computer’s display, logging off a user, or powering down a computer, Powerwise can display a warning to the user. These warning popups appear 2 minutes prior to the power saving action and allow the user to stop the action.
In order to help the user participate in the strategy of reducing energy and emissions, you can display certain usage statistics to the currently logged on user at any Managed computer, as well as enabling additional power management that they can control. If the power usage tray icon is enabled, the user can view summary information for on, idle, and logged off time.
