Vista+switching+itself+on


 * Vista switching itself on **

even though the screen save is switched off, after 5 mins or so the log-in screen appears.

You could try going into the power options then advanced power options and looking at all the settings there. maybe something like wake timers are set or require passwords on log on may be set causing issues. Don't forget to press apply if you change anything.

Even though screensaver is turned off you could check that "on resume display log on screen" is not ticked in case that option still is active even if screensaver is off.

Also double check that "none" is selected in the drop down screensaver choices drop-down list.

Other than above suggestions can not think of any reason for issue.
