Issue with Win 7 Home 64 machine not requiring password after sleep mo

I have a Dell Inspiron running Win 7 Home 64 bit. Previously, it would require entering a password after it had gone into sleep mode. I found the settings that should cause it to do so, and they were set properly, still the machine is not requiring a password upon waking.

It still requires a password after a reboot.

Would appreciate any help.

Is it actually going into standby, hibernating (hybrid sleep) or just powering off the display and hdd?

Have you tried enabling the screen saver and asking that to show logon screen on resume to test if the problem is the standby or the loading of the logon screen when already logged in?

Not sure what it's doing. I just used to power-down after a period of not using it and would require my password to get back on. It no longer does that.
