high frequency buzzing

Hi. I recently purchased a Toshiba M100 and I hear a constant high frequency sound. Could this be my hard-drive? and is this something I should worry about? It's from Bestbuy so I can easily return or exchange. Thanks.

Where is it coming from? It could be the HDD, but you'd be able to hear it coming from it. It could be a fan as well.

 

It *could* be coming from virtually anything. You're the one who can hear it, not us.

Personally, I'd get it exchanged regardless of whether it's "something to worry about". It's got to be annoying to listen to, and I doubt it's supposed to sound like that.

 

It's probably a fan would be my guess.

 

If you don't feel comfortable about the sound, you can bring it to them, let them check, and ask them whether you can exchange. might be you can have a comparsion side by side to hear the sound and so on.

 

hmmm, i had the same thing, it was really driving me insane. I have a toshiba M105 which is a similar model. The noise seems is not the hdd, its coming from the processor/fan area. most hearable by putting your ear close to the keyboard on the left hand side or by the vent. I thought the problem was specific to core duos because when searching for the problem, i could only find a whole bunch of mac book pro users whiging about exactly the same noise. Mine has stopped? Could just have dissapreared over time but i can barely hear it not. I think upgrading the bios helped? but in the process, my graphics only shows as 64mb rather than 128mb....

 

Hello, I have just bought new notebook Satelite M105-S3041. I can hear quiet whining sound, which is changing with using the touchpad in Windows. It also occurs, when some application are started. When I put my ear near keyboard, there I can hear something as a permanent "electronic noise". It's not HDD or fan, I am sure. It is not annoying, but it is notable. Do you think, some new BIOS could fix it?

 

Capacitors will do this when they're failing. Many electronic components of questionable quality will make funny buzzing noises when they're on edge. Just keep an eye on it, figure out if you can reproduce it, and if it's worth sending it in on warranty.

 

I am not sure that my notebook is on the "edge". I hope, it is not! It is doing this quiet noise from the first start. It is changing with, I think, CPU usage. I tried to leave this notebook running whole day and it has been same all the time. Is there somebody, who has the same finding with his or her notebook from this serie? Thank you.

 

From the start they could have put bad capacitors in it. They're what keep the voltage constant and clean to the processor, and it could be that they just installed a bad batch on your motherboard. You should call your toshiba, and escalate a tech support call if at all possible and see if they have anything they can do. Buzzing of any sort like that just isn't right.
