I have a zBook 17 G6 workstation notebook that are producing a very high pitched electronic noise. It sounds similar to the kind of noise a bad capacitor, or other bad electronic components, that will be made in some electronic circuits. It can be very loud and is overly obvious in one of my USB headphones, of which it is a pronounced hissing and crackling.
I've seen other postings pertaining to this problem, but I have not found any official statements from HP on what the cause is, or if they will fix the problems. I did see a few comments stating that HP was unable to resolve the problems, even after sending in their computer a few times.
So, what is HP's official stance on issues such as this, that sounds like there may be bad electronic components that are producing high pitched noises?
