PC Deep Sleep Mode

[LyleH]

My daughter has a Dell Dimension 4600 running XP. She doesn't have much for tech support. Every time I go to her place the fan on the Dell is running. Isn't there a "sleep" mode on the Dell that is like the Mac's deep sleep, which shuts off the fans and draws very little power, yet will wake up in less than 30 seconds?

Maybe a "hibernate" mode or something like that?

I don't "do" PC's, so please be thorough in any explanation/instructions you might offer.

Thanks - LyleH
