So I just bought myself a Spectre x360 (13 inch, 8gb ram, 256 gb ssd, i5- 7200) a few days ago. Now the problem is that it makes an annoying electric like buzzing noise all the time. Watching a youtube video, scrolling a website or moving the mouse over any website, app or anything like that triggers it really. From the research I did I believe it's coil whine. I found a few other with similar problems. For example:
Found this solution but it can't be applied anymore since we can't acces the cpu c4 function in the BIOS
This noise is what I am talking about: https://www.youtube.com/watch?v=nIrkcDZn1G8
Anyhow, is this annyoing noise a case for every HP notebook, every x360? Or just a few?

I also have the coil whine on my Envy x360 Kaby Lake system. I used a reg hack to disable the lower power states. Visit this page - https://support.microsoft.com/en-us/help/975530/stop-error-message-on-a-windows-server-2008-r2-based... Ignore the hotfix. Scroll down to the bottom to that work around section and perform that reg hack. Coil whine gone on my system. But battery life has dropped like a hour with low power states disabled. But 4-5 hours of battery life is more than enough still. Should you want to just try the reg hack, you can restore lower power states by deleting that registry key.

I got it to work but it did not solve the problem for me, it still remains. The only solution to the noise I've found so far is disabling the intel hd graphics, but that isn't really a suitable solution. And the HP support isn't of much help I've have to admit. Still even though it didn't solve my problem thank you for time!

Yeah that is the only thing that fixes it for me as well. Might try to push for a return then, it's a shame though, it's a good computer beside that one flaw. Are you getting a new one or just returning it for good?
