AMD processor causes annoying high-pitched whine

Just got a new Toshiba M305D with and AMD processor, and I may end up having to return it. There's a faint but definitly audible and extremely annoying high-pitched whine sound. I've done a Google search and I now see that I'm not the first person to be experiencing this. (Oddly enough, there's a trick to make it stop, though it's not a permanent solution - open up the "Sound Recorder" tool, in the Accessories folder.)
Don't know if Toshiba has any kind of exchange program. Anyone have any experience with this? From what I've read, the M305s with the Core 2 Duo processor do not make the same sound.

Same problem here.  It's a very annoying sound, and not something that should normally happen with a laptop.  It's really pretty piercing and makes concentrating in silence difficult.  I brought back the first one I bought to Best Buy because I thought it might just be a defect, but the replacement they gave me (same model) made the sound as well.  I called Toshiba support today, and they opened up a case for me that will be submitted to management.  I have a case number and they should be contacting me with a resolution.  Hopefully they'll give me a credit so I can get a different model.  I'll post the resolution here if I remember.

  • Officejet 4630 printer makes high pitched whine even when not printing

     I just bought an Officejet 4630 printer for home use and noticed it makes an annoying high pitched whine whenever it's not sleeping, even when not printing.  Is not very loud, and would not be noticeable in an office environment due to ambient noise, but is obvious in a quiet home environment.  Is this normal for this model or is the unit defective?  Neither of my two previous inkjet printers made this noise.

    Hello,
    If your OfficeJet 4630 is within the standard warranty period, please contact HP technical support to speak to one of our agents who can troubleshoot and diagnose this issue.
    We look forward to your response,

  • A high-pitch whine from a KM2M?

    OK, this is REALLY upsetting me and I figure someone out there might be able to help.
    I bought a KM2M combo motherboard from a local computer shop about 3 months ago. I was using an AMD XP 1900+ w/ 192 megs of pc-133 memory.
    Well, I upgraded a few things and here's my current list in my rig:
    KM2M Combo mobo
    AMD Athlon XP 1900+
    Cables Unlimited Super Quiet "whisper" cooler w/ copper core (it dropped my cpu down from 104F to 84F!!!)
    8x AGP PNY Nvidia GeForce 5200 Ultra w 128 megs ddr memory
    512 megs(2x 256) Paired ULTRA DDR pc2700 dual-channel memory
    92.6 Gigabyte Hitachi Deskstar ATA-133 hard drive with hard drive cooler attached
    8x Lite-On DVD-+R/W drive
    2 80mm high-flow Speeze brand case fans
    300 watt ULTRA Power Supply w 2 blue LED 80mm cooling fans
    Scorpion see-through yellow IDE & Floppy cables
    Well, after a few changes, my mobo starts to make this REALLY high-pitched whine! Well I thought it might be the PSU or heatsink, so I go through EVERYTHING and NOTHING is making this sound! I even tried changing memory & power settings in the BIOS, but no luck.
    Well I set up this exact setup on a chaintech mobo and I get NO shrill sound whatsoever! (proof it isn't something outside of the mobo)
    Any ideas on how I can fix this? I would take it back to the computer store & get it replaced but my dog chewed up the box it came in a few weeks back so I can't take it in to get it switched out...  

    That is a fine set of stuff you have. The PSU also has a fine name, but what ampères does it give on 3.3, 5 and 12 volt? Try to localize the sound, for example by holding your hand to a device - not a fan! - and see if it is a bit loose, cause it sounds like something is loose, the Northbridge heatsink or a capcitatior, as you say.

  • High pitch whine in 23-g116

    Band new computer and there is a constant high pitch whine coming from within the all-in-one computer.  Have ajusted settings to power saver and no change.  Any suggestions on how to correct.  Very annoying.

    Hi Gary,
    It might very well be that a piece of an electronics circuit is causing the whine. Your ears may be more sensitive than others but this issue has occured with other PCs.  Your PC is under warranty so I would contact HP Support.  I know some PCs have been replaced due to high pitch whines.

  • High pitch whine when recording audio & voiceover in iMovie

    I have read other posts on similar issues but found no resolution
    Issue:
    When recording video in iMovie there is sometimes a high-pitched whine which renders the video useless. 
    The problem was intermittent ... annoying but I wokred around it by re-recording the video enough times to finally get a "clean" copy.
    Now I am recording voice-overs for some clips and the awful whine is present in ALL the voice-overs. 
    I have tried the "trick" of using brighter light.  No joy.
    I have tried adjusting the microphone settings.  No joy.
    THis is an older macbook ... so I can't trade-in for a new one on warrantee. 
    Is Mac's internal microphone defective?  I have read enough other people have similar issues to think this.
    I am doing educational videos.  My initial joy at being able to record a video on my macbook is changing to despair as I have wasted hours of time on tech problems like this. 
    Anyone have a real fix? 
    Is the built-in camera and mic just shoddy junk which doesn't work well?
    Thank you

    Did you do the usual stuff, such as reset PRAM?
    http://support.apple.com/kb/HT1379
    There are some sound settings in PRAM, although I think it's only for sound output.
    Also, as a test, I would create a new admin user account in System Preferences Accounts pane
    http://docs.info.apple.com/article.html?path=Mac/10.5/en/8235.html
    Log out and log in to the new account (do not use Fast User Switching). In the new account, try recording something using QuickTime, and note if this problem recurs. If it does not, you have eliminated a few possible causes, such as a problem with the overall system installation or a hardware issue, and isolated the problem to something in your normal user account.

  • 21.5" iMac High Pitched Whine

    I've had my iMac for a few weeks now and it's an amazing machine.
    But my biggest annoyance is a High pitched whine like some say, The sound of a Dog Whistle or the sound of an old CRT TV, during lowered brightness.
    It is hardly detectable at Max Screen Brightness but I just can't work with this at full brightness. Soon as I lower brightness to 1/2 which is my preference, the whine does get really annoying especially while doing online Homework for hours.
    Sometimes I can forget the noise but every few moments the sound just gets to my ears. SMC & PRAM resets doesn't fix this.
    I heard many responses on here but nothing much about the cause of the problem. Whether if this is normal and I have really good hearing or What?

    Hi,
    I hade the same problem with my purchase of the entry iMac 21.5 model.
    After 3 replacements from AppleCare, they didn't want to make any further replacement - but offered to give me a full refund. (which I took - since I can't bear to live with this sound).
    During all of this, I took video & sound recordings of all the iMac they sent me ... and bored as I was waiting for them i went to all of my local retailers and wrote a list of Serial No. of which in-store iMac's also had this problem.
    From 9 pcs of iMacs (a mix of 21.5" and 27"), 7 pcs had this issue and 2 pcs I couldn't make a call on if it had this issue or it was to noisy ambiance (to hear clearly) - but lets say 2 pcs passed ...
    Even so, 2 out of 9 isn't that much better of a result then 9 out of 9. Pretty crapy odds against ...
    Also, during a call with AppleCare I found out that the 1st two iMacs where manufactured the same week (very close to each other) - week 26 (beginning of july) (double check with my retail store, and they confirmed that the weeks corresponded).
    After all what I've gone through (worst Mac-buy experience ever! ... and I've bought a handfull of stuff from them the past years!) ... don't buy an iMac of Middle 2010! as all odds are against you!
    Maybe if Apple recognized the issues they have, and made a recall of all the effected models, ... then maybe; maybe then.

  • High pitch whine noise from speakers and other issues

    I just got a 2010 Mac Mini and transferred all of my data and apps and accessories from my old Mac Mini which was running 10.6.4 (2007 I think). One of the accessories is a Griffin Firewave. I had to get a new firewire cable to attach the Firewave since the new Mac Mini has a firewire 800 port. On the old Mac it worked great, I was able to run 5.1 speakers with no problem. With the new Mac things aren't so nice. I get a high pitch whine through the speakers. The whine will go up and down in volume with the volume control on my sound system (Klipsch Promedia 5.1 Ultra) as well as with the Mac volume control. I can increase the gain in the Firewave app which will increase the volume of what I want to hear without increasing the volume of the whine, however it will cause the audio I want to hear to distort. The other issue I have is that when I put the Mac to sleep it seems to cut all power to the firewire port, causing the Firewave to turn off and lose its settings. I believe this to be a bad design on the Firewave's part but the old Mac did not shut off the power to the firewire port when going to sleep so this was not an issue. So my questions are, does anyone else have problems with external sound cards having a high pitch whine noise and is there a way to prevent the firewire port from turning off when the Mac sleeps?
    BTW, I have tried reinstalling the Firewave driver (several times) and I've unplugged and re-plugged the firewire cable at both ends. I have both the Mac and the sound system plugged into a line conditioner so I doubt it's dirty power. I do realize that the Firewave only claims support up to 10.5 but it was working without issue on the old Mac Mini on 10.6

    I have the same problem. I have an early 2009 Mac mini and get the whiny noise from my powered speakers. The volume of the whine noise tends to change smoothly up or down, and often does a stuttering effect along with it. It stays there for up to a minute or so and then eventually goes away. It always seems to happen at random times.
    I've heard this same sound effect coming from a podcast that I was listening to on my iPod Touch. It seems that the interviewer was recording from a Mac mini as well, though not sure. The sound in the recording was exactly like what I hear coming from my Mac mini. I often thought that this was a problem with my speaker system, but was surprised to find that others are experiencing the same kind of issues.

  • IMac High Pitch Whine

    Hey
    I have this iMac that I've had since Oct last year. Recently I've noticed that it has a high pitch whine.
    I can't figure out were about from the iMac it's coming from as when I get closer I start to hear fans (ear right next to it)
    But maybe the top left corner.
    I haven't used any fan control programs, and my temps and fans speed are all good by iStat.
    I haven't got 10.5.2 but .1
    I leave my mic off, brightness near all low, sound low unless listening to music.
    Please help as my iMac is in my bedroom and I can hear this whine like a muted TV, but coming from my iMac
    Thanks

    I have the same problem and am trying to find a solution. I have an intel iMac Alum 20" 2.0ghz, 2gigs Ram, Radeon 2400XT, 250 Gig HD. The noise started after about three days of ownership. I have this for almost two weeks now. I cant find any solutions and have talked to Apple over the phone they suggested taking it to an Apple store and let them take a look at it, but I live an hour away from the nearest store, so this is a pain. But yes, the whining is annoying and loud at times. It whines for like 1-2 seconds going from a low pitch to a high pitch in those 2 seconds. It then stops and comes back maybe 20 seconds later. So thats been happening for about a weeek now.
    Then all of a sudden early this morning (4AM), while the computer was in sleep mode, I was awakened by that same high pitched sound, but it wouldnt stop, I had to get up and turn the computer off. I would definatley love to get some answers and have this fixed. I've read many posts now with people having similar experiences. Just want my precious fixed.
    Nothing has helped ie; turning the sound down, muting it, turning off my internal mic, messing with sound options.

  • My Raid developed high pitched whine

    my raid has developed a high pitched whine.
    will Raid utilitie help me determine which drive is going bad?
    I believe it is a raid 5.
    in theory i can swap out that drive with a new one, correct?
    what is the proceedure for that?
    thanks

    First, press the sound button on the xraid to disable the annoying sound.
    If the disk is realy bad, a red light will flash on the disk. Since you did not mentionn this, there is another probem.
    To find out use the Xserve Raid Admin GUI to find out. You can find it on the CD that came with the xraid, or [here|http://www.apple.com/support/downloads/xserveraidadmintools151.html]

  • High pitch whine/noise coming from 880G-E45 when PC is off

    I just recently built a PC with the 880G-E45 motherboard without any major hiccups except for the fact that my PC makes high pitch whine noise (similar to a charging flash bulb on a camera) whenever it is powered off. When the PC is on and just after the PC is turned off, there is no high pitch whine at all.
    From what I can tell, the noise is not coming from the CPU, but the corner of the motherboard where the 3 LED-lit RESET, CLEAR CMOS, and POWER buttons are. I eliminated all other components of the PC by only powering them one by one and whenever the 24-pin ATX power cable is plugged in, the high pitch whine noise would be made.
    Is there anything I can do to silence this noise or is this normal for this motherboard? This is a problem since the PC is for my room which is very small and while i can't hear it during all the activities of the day, in the dead of night, it is loud enough to keep me awake. The only shorthand solution was to switch off the power on the PSU (BTW, will this damage my PC if I do this too much?).
    Here are my specs:
    -AMD Athlon Phenom II X4 840
    -880G-E45
    -BIOS: A7576AM3 V3.10
    -Samsung 1TB sata drive
    -Corsair CX430 V2 430w
    -Kingston HyperX Blu 4x2GB
    -Win7 x64

    Quote
    I'm guessing the power being output by the PSU is too much.
    Nonsense, the PC will only draw as much power from the PSU as it needs, not the other way around.
    Evidently, the CX430W is somehow faulty. Contact your retailer, or Corsair directly, and see if they will replace it for you.

  • High pitched whine from netbook when power is plugged in. Does not charge when computer is on.

    I have a specific power / charging issue On HP Mini Netbook 210-1077CA. Windows 7 starter ( I think)
    With the computer OFF ...
    When I plug in the power it gives a high pitched whine. Red battery light is on, showing it is charging. (computer is off.)
    To test the computer I have turned in on after charging for a little while and the % of charge is increasing. Showing that it is charging properly.
    HOWEVER,
    With the computer ON
    The battery light turns white and does not stay on, but flashes periodically. Its not a constant flash but a pause of several seconds between a series of flashes.  The manual indicates a Flashing Battery light seems to indicate either going into a sleep mode because there is not enough battery power (however my power is at 14% normally this happens I think at 10%) OR as the manual indicates there is a problem with the battery.
    I removed battery, removed power plug and then pushed power button holding for 15 seconds.  No change in behaviour.
    I also tried to boot the computer with just the power plug in and no battery. But it would not turn on. I don't know if that is normal or not?? Interestingly the White battery light, while trying to turn the computer on without the battery stayed white no flash.  (but did not turn on either as I mentioned.)
    I read a few posts that say that the whining are Capacitors doing some sort of harmonics. Although I have never heard this sound before.
    Im sure that this problem is not fans or heat sinks etc. Since in only happens when the computer is off  and charging. In my opinion its definitely electrical. The sound seems to be coming from the center of the netbook or the battery area..
    So my conclusion is ...
    1. Battery has problem and needs to be replace,
    2. Maybe the AC adapter is bad, since it doesnt boot w/out battery (if it is suppose to ??)  Also since it seems when I turn it on it goes from Red charging to white flashing as soon as it starts to boot. Could it be the AC adapter is not giving out enough power to charge and to boot at the same time.
    Anyway can anyone help me on this issue. Im not sure whether to start by getting a new AC adapter or new battery. I would not like to buy new both and just throw money at it.
    Maybe it is not either???
    You help would be appreciated.
    Regards. 

    I have resolved the problem.
    I replaced the AC adapter. Everying works find now. I tested runing the computer without the battery, and it works. So I might add that a possible test for an adapter that is not functioning properly is to try running it w/out the battery. If it does not run its possible that the ac adapter does not work.
    Thanks.

  • H67MA-E35 (B3) emitting high-pitched whine/chirp

    I am getting a high-pitched whine or chip coming from the bottom left area of the CPU/Heatsink. It isn't the fan, as I have stopped the fan and it still makes the noise. I was also able to correlate the vcore voltage with the noise. The noise is only present while the vcore is below 1.000v. After throttling over 1.000v it goes away. I am using a i5-2500k. I am not overclocked anything and made very few changes to the Bios (just boot order and things like that).
    Is this a problem with the socket, northbridge, or some other part on the board? Or is this a problem with the power supply not supplying the right kind of voltage? Or is the computer throttling too low? Like how a car doesn't run properly if idling too low?
    Thanks in advance,

    No, this is a very common issue with chokes since a choke is very similar to a buzzer or speaker coil so if it's a bit loose, it can vibrate and emit high-pitched sounds.  It will not damage anything by itself so if you can get it to stop using settings that are otherwise safe then there is no need to worry about it.
    - D
    I believe this is more common with iron chokes.  The ferrite chokes used on this motherboard are far less likely to buzz.  I did look at the board photos and it looks like the CPU PSU is standard FET transistors.  Hmmmm.

  • Certain iTunes "matched" albums produce high pitched whine after downloading the "matched" version?

    I have been begun using iTunes Match and I have encoutered a problem.  After importing two of my "Stargate SG1" soundtrack CDs (http://itunes.apple.com/us/album/stargate-sg-1-soundtrack-from/id28057422 and also http://itunes.apple.com/us/album/best-stargate-sg-1-soundtrack/id285158287), a very noticeable high pitched whine is heard during playback.  This is not a problem with my macbook pro as the downloaded file on my iPhone makes the same noise.  What is up with these tracks? Is there something I can do to fix it? These copies that produce the high pitched whine were the files directly downloaded after the match (so I could enjoy the higher bit rate). What's going on?

    I called Apple today to get my 24.99 back! This has been the worst exprience I have ever had. At first I was excited that almost all my songs were matched. I figured I would be able to upgrade the 128 to 256. YEAH OK!!!
    What it did was give me all radio versions of my hip hop music not to mention stuff like korn. I couldn't handle it anymore. I decided that I would feel a whole lot better ripping them all over again at 256 myself

  • High pitch whine

    My iPod is all of a sudden started to make a high pitched whine. When i plug it in and after i turn it off.

    Try this: (this will not damage your music, dont worry.)
    starting with your ipod on:
    1) flick the hold switch at the top back and fourth three or four times, stopping when it is off, so that you can still press buttons.
    2) hold the center and menu button simultaneously, until the ipod shuts off, and the apple logo appears and your ipod turns on.
    Good luck!

  • High pitch whine and FireWire bus power

    Delighted with my MBP!
    Just noticed the high pitch whine today when I set it up in a quieter room and plugged it into an IOGear bus-powered FireWire hub shared with my other Mac.
    It was around 8000 hz and loud enough that I could not stand to stay in the room with it.
    When I unplugged it from the hub and connected the cable directly to the FW port, the whine was greatly attenuated (I could hear it only by putting my ear next to the vents at the top of the keyboard).
    Could the problem be related to powering the FireWire bus? (It reminds me of the sound of a switching power supply or DC-DC converter) Has anyone else had any success in finding ways to attenuate this high pitch tone?
    MacBookPro   Mac OS X (10.4.5)   7200 rpm

    Hi, Thanks for the suggestion. I'm really trying to cut down on the number of devices that I leave plugged into the mains, so would ideally like a solution that relies purely on power supplied by the internal bus.
    I've had a bit of progress with my current set-up. I've switched to using a 2 headed USB lead that came with my Hard Drive. This does mean I effectively lose a USB socket, but it appears that the Hard Drive + the Webcam can now live happily together.
    It just means that I have to swap the 4th USB port for whatever ad-hoc device I need to use at the time rather than leaving things connected to it.
    Out of geeky curiosity, I'd still be interested to know whether the USB and Firewire buses share their power or each have a dedicated amount.
    Cheers,
    Ian
