Sony Vaio with Vista

Question

I bought a Sony Vaio (model PCG-7V2L) with Windows Vista in August. The power settings have never worked right. The screensaver comes on, but the display never shuts off or the computer never goes to sleep on it's supposed to (no matter what power settings I use, or how I set the times). It also never goes to sleep when I close the lid, even though I have it set that way.Thank you!Julie [e-mail]
