Disabled password when screen powers off

Hi,

I've set my screen to turn off after 1 minute of inactivity to maximize battery.

When my screen turns on again, it always asks for the password/login.

In screensaver settings I have not ticked "On resume, display logon screen". I only want it to ask me for a password if the computer has gone to sleep/standby.

What setting do I need to change to fix this?

Thanks

(I'm on Windows 8.1)
