High pitched laptop noise

Post Reply New Topic

I had to get a new laptop as my previous one was unable to get out of 'automatic repair' mode and load Windows 10. It's a much better laptop , but has this constant , high pitch whine . It's not enough for me to freak out over , but is a little annoying- to say the least!

That's not ok if you bought a new laptop. Is it coming from the fan? Sometimes it's the soldering that causes these high tones as electricity tries to pass. Then there's also the electronic converter/transformator that could be the source.

I totally know what you're saying. The high pitch sound is unbearable. Thick tv:s used to be very prone to sounding, as well as cheap lamps.

And I would recommend switching from Windows to Mac. It takes a little while to get used to it, but once it's done you just can't go back. I'm on a macbook air from 2015 and it still feels every bit as fresh as when I bought it. A PC normally starts acting up within a year or two

I have no idea precisely where it's coming from . What I do know is that if I had a dog it would be going doolally .

Alright! We'll see how long it takes before it really gets under your skin.

(Also expecting someone step in to point out some facts regarding frequencies a dog can hear in comparison
to humans)

mechanic hard drives can make a whine........ usually not a good sign. mine stopped after a while , it seems to be operating well , even now. jjust my humble opinion.

Try turning the volume down.

What Jakki said. Hopefully the hard drive isn't about to fail. The whining from the old CRT monitors was the flyback coil at about 15KHz. If you could hear that, you didn't have hearing loss. LCD and LED monitors don't make this noise that I've noticed. If it's the fan, it needs to be cleaned, serviced or replaced. Not a 'fan' of disassembling modern laptops.

I'm thinking my sensitivity to such things is erratic, and possibly not totally related to the laptop. So far this morning I can't hear that noise . Last night in bed I was hearing a similar noise as the 'laptop' noise .

yeah, that's okay
