I have a Yoga Flex 5 and an X1 Carbon that both exhibit this. The Yoga is particularly annoying because it also has some little crinkly noises from the left speaker that come with the whine and make me wonder if it has a spinning platter HDD sometimes, and the X1 is just inexcusable at that price point (but it is a company laptop, so I can't really return it).

The coil whine was (relatively) less of a nuisance than the X1's fans, though, which were ridiculously noisy until I set the thing to 80% CPU speed.

So yes, Lenovo, if you're reading this, your customers have to kneecap your hardware to use it. Way to go proving value here.
