I'm using the new HP Spectre x360 laptop and I'm experiencing an annoying issues. Whenever I connect the charger there is a "metallic" noise from the laptop. In a quiet room there is no problem hearing it. Almost sounds like an old mechanical hard drive but more metallic and high pith. I only hear this when the charger is connected
I had the laptop replaced by this but still have the same issues. I have three different original power adapters and I have the same issue with all of them. I have also tried to disable the keyboard baclighting since I read that could cause issues previously.
I don't really want to send this one back too since I think that the third laptop will have the same issue. Mst be others noticing this? Any solution, workaround or clue what is causing this?
