While running any program that demands power I can hear a buzzing sound coming from the USB-c port and power cable. When I increase movement in software or games the buzzing sound increases. I have changed the USB-C locations on the laptop but I still have the buzzing sound. The buzzing sound goes away when I unplug the power. If anyone has and suggestions I would love to hear them. Thank You
Coil whine on the port is a bit weird. Does it change if you take the adapter plug out completely and plug direct to the motherboard?
I’ve tried to cure whine on laptop boards before by sealing capacitors with superglue, but if your issue is coming from the port and power cable, I don’t know how much this would do for you. I guess another solution would be to change power supply/charger or try fiddling in-game settings if it really bothers you.
A framerate limit might let you change the power draw just enough to stop the extreme end of the noise, but you’ll always have some whine when under load, it’s just how these components work.
For whatever it’s worth, I have heard coil whine similar to what you describe, but only once or twice. Normally I never it.
I plugged directly to the board and there is still whine. I am starting to think its on the board because the sound is coming from both sides regardless of where it is plugged into. it is way more noticeable since I reduced the resolution and setting and the fans are not going crazy. It maybe something I have to deal with while plugged in but I was wondering if there is a solution or is anyone else is having this issue.
ohhh
random superglue would make be nervous. Personally, I’d try something that manufacturers themselves tend to use to help power supply noise, like a neutral-cure silicone. Hot glue is an alterative. Seriously, hot glue is often used on PCBs. And it has the benefit of releasing with a little rubbing alcohol, should you later wish to remove it. Rubbing alcohol is often used to clean soldering flux off boards, safe for PCBs. Should be high percentage, 92%+.
Hot glue wouldn’t solve the problem, because you won’t be able to get it where it needs to be to stop the resonance causing the whine. Manufacturers use silicon or hot glue because they can put it in place before assembly. Once the components are on the board, to use that effectively, you’ll need to desolder them, apply, then solder them back…
The use of the liquid type super glue is to make use of it’s wicking ability which draws it up into the cap and once hardened, stiffening the components vibrations.
It’s not likely to cause damage, those parts aren’t suppose to move anyway, and it’s not conductive. The example is for a desktop GPU but I’ve done it to a Lenovo legion and an Asus proart with good results.
At the end of the day, coil whine is down to the silicon lottery, a bit like over clocking potential. Some boards will just have more, some less.
I learned something today. Thanks for sharing ![]()
Sorry, huh? ![]()
Have you seen actual pcbs where silicone was applied to power supply components? It certainly is not applied before soldering. Liberal amounts are applied around the outside of components. It would get pushed where you don’t want it if you tried it before soldering.
Certainly, I imagine there might be boards with really nasty power supply whine issues where standard solutions aren’t enough, and wicking superglue under components might be your only option to quiet what is basically a defective board (if it’s that bad). But I’d try neutral-cure silicone or hot glue first. If worried that your whine seems bad enough that you might need to resort to superglue, then I’d leave the bottom edge open on one or more sides as a path for that, if needed.
It’s the component lottery, for some boards to a certain extent, but I don’t know if it the silicon that’s the biggest players (GPU or CPU). I’d more suspect other parts being near the edges of their tolerance ranges. And for some boards, part or all of the issue might be just design and / or part choice. Using cheaper caps. Parts with a tight tolerance range cost more. And designs that just have unacceptable noise when parts are fully within tolerance just a bit high or low. Noise is a often concern with modern SMPS, but it can be managed, and it should be, part of the job.
the only thing is this only started to happen yesterday. Would a drive update cause this. I also had a static charge discharge from my finger to the keyboard. I am wondering if that caused some damage maybe?
I’m not sure what your point is… what you’re describing then isn’t a solution on the manfacturer’s part to stop coil whine, it’s just keeping components secure on the board.
The topic here was solving coil whine, so…. Yeah?
Better quality inductors and cap sealing would maybe solve some problems, but with the power draw through modern components, you’d be asking for a QAQC process on these small cost items that would not be worth it in bulk.
Slathering silicone around the board will not stop coil whine. You’ be about as effective at soundproofing your car engine by sealing down the hood with duct tape. The outer shell of the inductor isn’t causing the whine, it’s the coil inside.
If you think the superglue is dangerous, then just don’t do it. Simple.
Power draw is the main cause of audible whine. (Well, that, and the physical components vibrating as a result)
If you did a bios update that stopped throttling (some of the recent ones were attempts to stop power throttling) or if you had driver updates that improved GPU usage in certain applications, you may suddenly have whine from higher power draw.
A static shock from touching the chassis is definitely not a cause unless you literally have cartoon superpower levels of discharge. (And you’d notice damage in other ways at that point)
It could also be related to differences in charger. Switching to a higher or even lower wattage charger might cause resonance at certain frequencies to suddenly become audible.
