i have a dell laptop with win7 ultimate on it. when i am done with the laptop i put the thing to sleep, never shutting down. lately, i noticed the laptop keeps showing me a Resuming Windows screen when i hit the power button now. its never done that before. prior to this new thing, i would turn the laptop on and when it woke up it would go right to the user login page for the windows splash, but now it shows the resuming page first, then the little scrolling bar, then it goes to the page. any idea what this is all about?
