....The noise from the power brick can be heard only in a very quiet environment and when you get real close, about one foot away. Not a problem.

Folks I've listened to the squealing noise (downloaded Mike's recording) and can concur with a few others on what's going on here.
I learned about this noise first-hand recently after purchasing an HP printer. The printer's power adapter makes the same type of squealing noise. Some component(s) inside the power adapter are obviously causing the squeal (possibly a coil or two?).
Anyhow, it's specific to the power adapter used. There are noisier and quieter ones. I have a strong suspicion that they will all develop the squeal over time and possibly even a hum too.
I called HP tech support and they sent me another power adapter (gratis).
The second one is much better than the first. It still has a very faint squeal, approx. 1/4 the noise level of the first.
