do you mean standby or hibernation?
standby is the operation which will act as if you wanted to switch users, while hibernation acts as a power saver when the comp is inactive.
If standby is your goal and you have a user login, you can do the following:
Code:
C:\WINDOWS\system32\tsdiscon.exe
create a shortcut with this path (this is the disconnect option)
once to the login screen, it should only take 10-15min for your computer to move into standby
