Noise when plugged in AC

When the power adapter is plugged in, I hear a strange noise.

Is this normal?

He stopped immediately if I unplugged the AC!

Never heard when you use only the battery.

Thank you

Hi val

AFAIK, it is possible that there is little noise but is not strong. If this strange noise is loud in my opinion, it may be the beginning of the end. This adapter is not cheap and if your device has a valid guarantee you should contact the Service partner and change it.

  • PCI-6733 signal noise when the computer screen is plugged, the weight on the case

    Greetings,

    I hope that it is in the right section.

    Card: PCI-6733

    I'm a 60 Hz, 2 mV peak-to-peak with a compensated 2.4mV noise when the monitor is plugged into the VGA port.

    Same card in a second computer, problem is more serious, 4mV Ridge to Ridge, 4.3mV offset. When I push on the case near the power supply the offset rises from a few millivolts.

    The two computers are running the same exact versions of software and drivers. Dell and quite similar to each other in both material and form.

    I have a third computer that noise coming out of the map is horrible no matter what.

    I exchange business cards and the problem is with the computer, does not follow the acquisition cards.

    No idea how to solve this problem and what is the cause?

    Thanks for any thoughts!

    Tall_Michael,

    Looks like you may be plugging your monitor and your computer in different points of sale.  If this is the case, this is probably the cause of your noise and can be eliminated by connecting the two devices on the same socket.

    Here are some articles that deal with the noise you are experiencing and various workarounds in the cases where what I mentioned above are not the case:

  • My old iphone 6s is completely broken, it does not or registry that it is connected when plugged into a computer. I'm able to recover photos from the SIM card with an adapter USB SIM card or through any other way?

    My old iphone 6s is completely broken, it does not or registry that it is connected when plugged into a computer. I'm able to recover photos from the SIM card with an adapter USB SIM card or through any other way? I also do not save anything with AllAccess, icloud, or through my computer as you would with a digital camera.

    The photos are not stored on the sims, sorry.

    You can always try the Recovery Mode, little to lose at this point. If it doesn't, I suggest taking it to an Apple Store for testing.

    Recovery mode:

    Turn off your iOS device.

    Plug charge cable to the computer only (not to the device yet).

    Open iTunes on your computer.

    Hold the button to power on your device and do not let go.

    Plug the cable into the device while keeping the power button.

    Wait for the computer to detect the device and wait that he eat.

    Restore as New first, then restore sauvegardΘ if you wish.

  • Tecra S1: Notebook generates noise when the LCD display is on

    Tecra S1 is 4 years old and generates a high noise when the LCD is turned on (from last week). The noise comes most of the keyboard. Could this be a defunct ups?

    Is there an easy way to fix it? It's not very loud, but in a quiet that is audible.

    Hmmm I think this noise comes certainly from the FL inverter.
    But I can't tell if the inverter is faulty or not because I noticed that her top on different laptops when the brightness of the display is placed on the lower floor.

    But if you think that this problem was not present in the past, then you need to contact a technician who could help you replace the inverter FL.

  • Re: Satellite L500 - crackling noise when audio plays

    Hi all

    I bought a few weeks ago L500 (Windows 7 64-bit). Everything is fine except for the sound. 1 h or more after running computer, the speakers begin to produce a "cracking", "metal" noise when the audio is reproducible, regardless of the source (CD, system sounds, movies, MP3s...). It's just like there are hundreds of "micro-pannes". The same thing with the headphones. This seems also affect all media files, for example the length of 10-minute videos take 12 minutes or so play due to these micro-interruptions. The sound gets worse over time and gets normal once the system is rebooted, but a few minutes later the noise comes back.

    I have all the latest Toshiba driver implemented to date, BIOS, LAN, sound cards, etc..

    What can I do? Any idea will be welcome.

    Thanks in advance.

    Hello

    I don't know much L500 series but creaking sound is annoying problem for A500 series. I think that a graphics card driver is a troublemaker. If your laptop is equipped with an nvidia graphics card, go to his site and update a Vga driver. In my case, it solved my problem. (B-)

  • Qosmio G20: Fan makes an awkward noise when he turns around

    Hey everybody,
    Another problem, but not Vista! Although it is always a problem!

    My exhaust fan makes a clunky noise when it runs. I hear it's going along and round like a noise of rachetty and then at other times its fine.

    Someone at - he had this?
    Should I open and give it a clean?

    Hello

    It's not easy to tell if the fan is malfunctioning or not.
    Qosmio G20 is a laptop very powerful and cooling modules are larger and stronger as modules on any of cooling for powerful laptop.
    If you use the solid performance applications such as games or videos of the cooling modules will work with maximum performance and are stronger.

    But of course; the cooling module could malfunction. In this case, it must be replaced.

  • M601: Manufacturing of Laserjet M601 clicking noise when printing

    I have a laserjet M601, which has just started to make a rattling noise when it prints.  Looks like it is close to the top right corner before somewhere under the screen.  It snaps when a page is caught to start printing.  I hear a 3-5 clicks when the paper is caught, then it stops for the rest of the page.  If multiple pages print, click before the beginning of each page to be printed.  All other prints are normal.  The print job ends very well and all is well.  I only hear it clicking now and it seems to be deteriorating.  Thoughts?  Thank you.

    Hello

    I have some further thoughts on this. Are you sure that the manual tray loading produces noise? They use different pickup assemblies. If we have confirmed both tray 2 and Tray 1 (manual feed tray) produce the same noise that we have to look at what they have in common. Toner, transfer roller, editing of the main landing gear, & fuser.

    What type of toner cartridge do you use? If possible can you exchange with others and print a test page? If the problem persists, what is the number of pages on the printer? Have you recently replaced a maintanece kit?

  • Noise when using computer

    Suddenly, when I use my computer to get on the internet, I hear a thud. It happened once before, but suddenly disappeared. I wonder if the fan may be bad. Any ideas on what is the cause? The only other time that I hear it is when my computer is near the end of the scan of Norton fuul. This was bought in 2009 is therefore an old computer.

    PS Now I don't hear the noise, but most of the time I hear the sound when you go to different Web sites.

    I tried your suggestion yesterday and by changing the diet plan of the balanced or recommended energy saving plan has worked. I don't hear any noise now.  The performance for power management is not as good as it takes more time to load web pages, but I prefer this to the noise. He said beside the plan of standby power energy savings is rated with a 5 and the performance is rated a 2, while balanced or recommended plan has energy savings, a 3 and performance 3.

    I've always kept it on the recommended plan, which I think is the plan by default as it was defined like this when I bought my computer.

    Out of curiosity, why is she become necessary now that I change for energy savings?  I have that noise when I got to my computer. Is this because the computer is older?

    The information that you sent me has also stated the following:

    Some parameters to cause fans to turn too fast for a typical home environment. If you use the computer in an environment quiet where temperatures remain mild and stable (up to and 30 degrees Celsius or 86 degrees fahrenheit), and then follow these steps to adjust the power settings in a more appropriate setting:

    Do you know why the environment calm and temperatures are a factor?

    I waited until today to answer that I wanted to test it for another day. I also put it to (balanced) recommended plan and the noise comes back then I then changed once again to the energy saver and it will keep on saving.

    Thanks for your help.

  • network printer old now not recognized when plugged as local printer (USB)

    Have a printer all-in-one Canon MX330 which was connected through networks of my PC Windows XP Dell Dimension.  Now, however, I just want that he plugged on the USB local port, but when I do that XP is not pop - up dialogue "New hardware found", is not 'install' from the printer and does not add it to my list of printers.  The printer and the USB cable work fine when plugged into my Mac.

    I deleted the printer in the printer/fax list, so it does not appear there more.  And when I try to install manually (which I don't like), it will not print anything.

    Is there somewhere else I need to remove the printer? Is there a conflict with his definition of network printer? And, it is a very stupid question, but when I install manually, should I select LPT1 or USB01 as the location of the local printer?  Seems logical, it would be USB01, but it does not work (here again, or not LPT1).

    Completely uninstall and reinstall following the instructions here .

  • Pavilion dv7: HP Pavilion dv7 has no power even when plugged

    My laptop battery ran out today and would not take a load... I checked all the cord etc. and it is the power of the laptop, but now the battery is completely dead and the computer is also dead even when it is plugged into an AC.  I've deleted and reinstalled battery... no help.

    Is this a battery problem?  If it was, then, why the computer would not work when plugged in the AC?

    Any help would be appreciated...

    The first thing to try is a hard reset as follows:

    (1) remove the battery and unplug the DC power adapter.
    (2) press and hold the power button for more than 15 seconds.
    (3) plug the DC power adapter (leave the battery for now)
    4) press the power button

    If that produces no positive results, then continue with the following troubleshooting instructions.

    Is there a light power light on the laptop when the piower adapter is connected and connected to a domestic supply?

    If this isn't the case, then the laptop adapter may have failed and is unable to charge the battery or power the laptop on its own.

    Acts of power as a diagnostic power adapter LED and not lit is an indocation external power is not OK.
