I recently installed Windows 8 RTM, but found a very annoying thing. My PC always powered on automatically even in midnight. Eventually I noticed that I can power on the PC by pressing keyboard or mouse, and even moving mouse.
After searched this in Google, I turned off Sleep and Hibernate in Power Options -> System Settings -> Shutdown settings, but it still did not work.
Would anyone please help me? I don't want to suffer from the noise of PC powering on in midnight any more.
