Buzzing is not usually normal...   The power cord goes into the power supply/PSU, so is that where th sound is coming from?

100% certain.  Buzzing can be heard from 2 feet away.

IBM rep made a house call and replaced PS.

Same issue. FML.

 

Is it possible that a better surge protector could fix the issue?

We also having big problems with noisy power supplies on a lot of our new M710t and M720t Desktop machines. The PSU of one M720t computer was replaced two times by Lenovo technician to get an acceptable result. Some machines are louder than others and only one or two of the charge are completely silent. It seems that many people can't hear this frequencies and/or aren't working in offices silent enough to hear it because Lenovo support told that this is not a known problem so far...
