I'm running a Think Pad T61, and find that power state changes will also change the state of a high pitched annoying noise. It seems like this annoying noise likes to happen in full power mode, and stops in power saving mode. Any thoughts on how to cut it out?

Also, it's not the fan.

No seriously, it's not the fan.

My guess would be some type of 'green' HDD that varies it's spindle speed depending on the system load. I don't remember ever hearing about them though.

Yeah, I guessed the same thing, but the sound is localized to the area around the processor, the HD is on the opposite side of the base. Some googling revealed other users having similar problems under Linux distros using different reduced power states, and no pertinent solutions.
