I purchased a new Dell D620 a couple months ago with Vista pre-installed.

I decided to install my copy of XP on my new machine. After installing, I downloaded all the drivers from the Dell website and my D620 works great....except one thing: Neither standby nor hybernate are options.

Start->Turn Off Computer gives me:
"Sandby" GREYED OUT and "Turn OFF" and "REStART"

Start->Control Panel->Power Options->Power Buttons
"When I close the lid of my portable computer"
ONLY ONE OPTION: "Do Nothing"
"When I press the power button on my computer"
Three options:
Shut down, Ask me what to do, and Do nothing.

How do I get Hybernate as an option?

Thanks!
