other, I'm right there with ya, mate. Mine has the whine, and I don't think it's related to the Intel chip(s). I think it has more to do with the power inverter (?). The only time I don't hear it, thank goodness, is when I have it hooked up to a 19" widescreen and a bluetooth external keyboard.
Then all I have to contend with is the g*d d*mn fans spinning up because using the external monitor ramps up the CPU temps by about 5 or 6 degrees and opening, oh say, Dreamweaver when, oh say, just Entourage and Word are open causes the CPUs to say "J*sus, this guy really wants to work hard, doesn't he!?". I mean, good lord... It may be Intel's issue, sure, but how about that thermal paste, hmmm? Applied it correctly did we? Let's hope so.
Sometimes I think I was better off with my old 1.2Ghz P4 IBM Thinkpad X40 whose fan hardly ever spun up. And it was plenty fast for what I needed it to do.
Colour me a recent switcher who is having second thoughts when it comes to the hardware, but NOT when it comes to the OS.
