Lenovo Coil Whine – Is it fixable? Or is it a reason to stay away from Lenovo?
by Timja on Hacker News.
I recently bought a Lenovo X1 Carbon. It makes an annoying high pitched sound. At first I thought it would be the fans and it will go away when I configure the dynamic fan speed. But it turns out it is “Coil Whine” and that is common among Lenovo laptops: https://ift.tt/cYDnN8J I cannot find any info on how to get rid of it. So I will try to return the laptop. If I can’t return it (Already removed Windows and replaced it with Linux), it would be a 100% wasted investment. Since I otherwise liked it, I wonder what replacement to buy. Are any Lenovo models safe from Coil Whine?
