Does turning the screen up to full brightness make it go away. Someone mentioned that stopped it for them, suggesting it's something related to the PWM backlight control... perhaps an inductor that needs a dose of epoxy.
Turning up the brightness does fix it, but only some of the time. Once I figured this out, I leave it at maximum brightness and still get the whine about 60% of the time.
