Norman,
do you have a double boot on that machine ? If so is the noise same also 
under the other OS ?

Did you try muting all unnecessary audio ports ?

PCMCIAs like modem, eth or other nearby sources of EMF interference ?

Same noise with video backlight turned off.

Have got powernowd running ? Is noise same under all CPU frequencies ?

Is the noiuse the same with the CD/DVD unit pulled outside ?

Is the noise same with the battery pulled out ?

Did you try with another power source ? Plugged into a grounded outlet ?

An if all else fails, are you religious ? If so why not try with a 
priest blessing it ? :) :=) If you are not religious, did you get your 
hearing checked :)

HTH,
Bob
