Computer nerds: can you tell me if this noise is coil whine?


This sound comes up within a minute of turning on my laptop. If I put it on sleep it goes away. If I'm on a while, it does come back at random times.

Sounds like a fan noise to me.

Signed, million man.

It does to me too, but a friend of mine said it sounds like coil whine.

💯

Your computer is trying to prevent you from posting puns.

Skynet may not be as bad as we think.

Agree, it sounds like a fan issue.

reply

It does sound like the fan, but I think it's strange for it to rev up like that when first turning the laptop on when it's not even hot. And even if it was hot, why would it go down after a few minutes?

reply

One our new Alienware computer at works sounds like the space shuttle taking off at times for no apparent reason (I assume Microsoft is updating it's spyware). I don't think they make computers like they used to.

If you got a shop you trust (or friend), have them pop it open and take a look.

Unless you know what you're doing, I do not recommend you attempt to take a laptop apart by yourself.

Hopefully it just needs a good cleaning or replacement.

If it breaks, we can provide you with our mailing addresses and you can send us your puns by regular mail.

I blew the shit out of it (no, not like that) thinking that it was some dust buildup or something, but it didn't do anything.

reply

Running a large magnet over the laptop for about three hours might help.

Um, no... that's how you erase the hard drive and turn it into a brick.

How will he ever know if he doesn't try?

I mean, harddrive failure is but one possible option but it could also increase the hilariousness of his puns by 16% - it seems like a chance worth taking.

reply

Yep perhaps.

reply

Don't worry. I'm not an idiot.

It's most likely a noisy fan or something else that's spinning, which, in a laptop, could only be a disc in an optical drive (if you even have an optical drive) or the platters in an electromechanical hard drive (if you even have one rather than an SSD). A fan is by far the most likely though. An optical disc drive or especially a hard drive would have to be in pretty rough shape to sound like that.

Coil whine is a very high-pitched, ear-piercing, tone (there's no mechanical component to the sound like you're hearing), and there are no coils in your laptop anyway. Coils in a computer are in the power supply, which, for a laptop, is an external brick that the power cord is connected to.

reply

No disc drive of any kind. If it's the fan, should I be concerned?

reply

Not unless it stops working, but computers normally have a safeguard against overheating if that happens. I would just replace the fan and clean out any dust bunnies in there at the same time, but laptops tend to be a pain in the ass to work on, because getting them apart in the first place can be a Chinese puzzle in and of itself, and there's no standardization, so the procedure varies from laptop to laptop. On top of that, even if you find a tutorial for your particular laptop, sometimes those hidden plastic snaps don't like to come undone without breaking/cracking something.

reply

Thanks. I'll probably just try to take the dust out with an air blower without opening it up. I don't want to mess anything up by trying to take it apart.

reply

Or, just replace it.

reply

Andy, please.

reply

Pfft, it works for me 🤷‍♂️

change SLEEP to HIBERNATE

never use sleep

reply

It doesn't matter because the sound starts within a minute of turning it on.

reply

I know, but SLEEP drains battery shortening it's life, gets hot if stored in bag, genreally wears out your whole system faster.... causing weird sounds.
HIBERNATE effectively turns it off, saving battery, heat etc, but continues where you left off AND does cleaner network and hardware connects.

Definitiely air blow it

reply

Honestly, I don't even know which one I'm using. It's got a "z" on the keyboard and the entire computer sounds like it shuts down so I assume that it's sleep and not hibernate. If I'm downloading something and I hit that key, the download will stop.
