Hello
My wife's Dell laptop is emitting a noise intermittently. I finally pulled up what it sounds like = quite like the buzz when the TV screen crawls with a test of the public warning system --- only steady, not Bzz - Bzzz -- Bzz. And not so harsh.
It comes and goes.
I'll sneak in and find out what model the computer is when she's not looking Win 10.
Anything simple offa the top o' yer heads?
