I have the opposite problem I cannot get windows 8.1 to stay asleep I put it in sleep mode via the keyboard dedicated sleep button when I go to bed But when I get up in the morning it is usually running ?

There is nothing set to run that would waken it I am sure there is no virus running or anything like that that would waken it As its a new install on new hardware and its done that from the very start I did wonder if it was my nas drive If when i accessed the nas unit The pc started but its not that either Did think it may be wlan But so far could not see a setting for it in the Uefi bios Any Ideas.
