When resuming from standby or sleep users are not forced to login to access the workstation.

Power Save provides the option to "Resume from Standby Password Challenge" that will require the user to enter their Windows password when the computer resumes from Standby or Hibernate. If the user is not being logged off when the machine goes into Standby or Hibernate then use the "Logoff before Powering Down Computer" option.
Can Power Save override the settings built into the operating system to save energy?
When my PC goes into Standby I have to use the power button to power up again. I should only have to move the mouse or touch the keyboard.
