You watching: Laptop charger makes noise when plugged in



Greetings. I tried to launch a CPU intensive game this day, and also as quickly as I begin it, I hear some kind of a quiet buzzing sound coming from my AC adapter. As quickly as I shut it, the noise is gone. I"m founding to worry that the adapter might be dying. Tried different power outallows, very same trouble. Does anyone know if it"s normal or what is actually happening?

It"s referred to as coil whine. It"s generally quite normal and nopoint to worry around, a coil in the power supply is hitting a resonant frequency under fill and also is vibrating therefore developing the buzz. It"s a really widespread phenomenon found mostly in GPUs once running at exceptionally high framerates say in a food selection or somepoint, or in power gives.

Wow, currently this is somepoint brand-new. The fun component is that the sound appears and disshows up exactly when I desire it to. For instance, when I cshed the game or ALT+TAB from the game, it"s simply gone. Hopetotally it won"t melt, because I currently had actually one adapter melted, after I messed it up a while ago.

Well yes it will certainly most likely show up and also disappear depending upon load, if you cshed a game or alt-tab from it you simply took a huge pack off of the power supply. Coil whine wont cause a power supply to melt lol.
Thanks, I do not recognize much about electronics so this sort of worried the heck out of me. Best of luck to you!

if your lapoptimal is still under warranty you might constantly try to obtain a replacement adapter from the manufacturer or purchase a brand-new one that will certainly job-related for your laptop
Yeah, I did some study, appears like a pretty "natural" point. The adapter I"m utilizing is a replacement one, not an original adapter, but I"ll definitely get a brand-new original one in the close to future, as lengthy as it"s simply a coil whine.

Is it simply some cheap power brick you got on amazon or something? If so acquiring an OEM brick would not be a bad idea. Usually quality power supply"s coat their coil"s is some type of rubber or plastic to try and proccasion coil whine, cheaper power supply"s regularly wont.

Pretty much yeah. I"m a student, and short on paper at the moment, so I decided to cheap out on a power adapter, which is not an excellent point to carry out, of course. Problem is, I have an ASUS K501, which needs a 4.74A adapter. The original one is pretty expensive, it"s about $80. But I"ll buy a brand-new one, for currently I"ll stick to the buzzing one, it doesn"t bvarious other me also much..

But I"ll buy a new one, for now I"ll stick to the buzzing one, it does not bvarious other me too a lot..
just to remind you that it is understandable if you are on a tight budobtain and also have to cheap out on some things however cheeping out on something major like a power supply for a lapheight is not really among those points. this can begin out as coil wine yet next can be a power surge from it malfunctioning and also then you will be out a lapoptimal which will certainly price a heck of a lot more then a power adapter
