I am trying to set my computer to shut down to 'Hibernate'. But the 'Power Button' is not visible in the notification area of the taskbar (which is mentioned in my Windows 7 book. I have just installed Windows 7 on my desktop computer after using XP for several years OK. I have been into Control Panel, Power Options and tried various combination of the settings but none have revealed the Power Button or allowed me to Hibernate state. Can anyone explain how I can accomplish what I want to do.?
