Any new CPU/CPU features to enable an automatic sleep mode ?

[ben2e]

I believe I read something about Yonah or the new mobile processors having advanced power saving features but is there anything else on the horizon ? With current CPU's taking 110 watts+ at idle, I'm curious about any CPU or motherboard features that'll substantially drop the CPU's power use when the machine's not being used heavily. Right now I can put my machine into hibernate mode automatically if I don't use it in a certain amount of time but the restart from that is annoyingly slow. I'd much prefer some more subtle sleep/wakeup mode. Does anyone know of a Motherboard/Chipset/CPU feature is out there or is on the way that works well for this and is reasonably seemless (vs wake or hibernate)?

Thanks,

Ben

You can set it up in Windows so that after xx minutes the computer enters standby S3 mode (suspend-to-RAM). Waking up is fast (3-5 seconds perhaps), and your desktop/applications show up exactly as they were before.

In Windows 2k you can set it by going Control panel>>>Energy options>>>Standby after xxx minutes.
There must be a similar path in WinXP.

You may have to set an option in BIOS between S1 and S3 modes. S3 is much more power-saving than S1.

Related question. Shutdown.exe can turn off and restart the computer in a specified number of seconds. Is there any similar command to make it go into standby? This of course does not include the Energy options section.
