Ultrabook dell inspiron 14z sound does not work

My Ultrabook Dell Inspiron 14z with windows 8 is about a year and I had no problem. However, since July 11, when my system updated automatically update critical windows my sound has not worked. When I restart the laptop it starts working again, but not sure after how long (or if after connecting to the internet) it stops working again. In my sounds-> record, I saw that Microphone array is selected however microphone is disconnected (it has a red mark on it). Help, please.

We have recently seen many reports about this sort of thing. Countiss Forum member wrote that it is because of Microsoft...

«KB2962407 update, which which says it fixed "Shortened battery life when an inactive audio device is not turned off on a computer running Windows".»

You don't have to do a system restore to get rid the updates; easier to go to Windows Update, view update history. On the top of this screen, click installed updates. Then just right click the update you want to uninstall.

Found this fix on eightforums dot com".

Try that and see if it helps.

  • Dell Inspiron 17R 5720 does not work with the charger. Charger is not recognized. No problem with charger.

    My Dell Inspiron 17R 5720 does not recognize charger. And unfortunately my warranty expired 2 months ago.
    It was plugged and work in the morning, but then in the afternoon I noticed he was running on battery only. It does not start without battery (charger just plugged).

    1 this is what I did to debug. Me and my brother, we bought the same computers Dell laptops at the same time a year and a bit ago. That's why a debugging purposes, it was good.
    I took my charger and plugged into his computer. And it works. Certainly not the charger problem I guess. And when I plug the charger my computer, green light is still on the charger. And I have the original charger provided with the laptop.

    2. now, laptop is running on battery only, so that means that this motherboard works. I think so.

    3. the next thing I did was charger disconnected and removed the battery from the laptop. Then I pushed and hold the "Power" button for 45 seconds to pay a royalty to the flea market. Charger plugged in but laptop will not start.

    4. then I booted the laptop on battery, went to the BIOS and check if the charger is recognized in the BIOS. No, it does not recognize charger. So, if this isn't a charger so what else can we?

    5 laptop has no strange smells so I don't know if something happened with the motherboard, but I guess that motherboard is ok because it works battery.

    6. I was thinking of updating the BIOS, but I can't do it, because it will be not be updated then the laptop runs on the battery, it needs to be plugged.

    Now I'm stuck. I don't know what I can do. I'm willing to spend a little more money on it to try to fix.

    If someone had such a problem in the past please let me know what you have done and if it fixed it.
    Or if anyone has any other ideas, I will be happy and appreciated the help.

    Hello and sorry for this late post. Just had this problem... If there is nothing wrong with the AC adapter, it's a software problem.

    Close the laptop... Unplug the AC adapter / CC... Remove the battery... Plug the power adapter... Start the laptop... Go to the control panel... Find and select the Device Manager... Batteries, left click... Uninstall Microsoft AC Adapter, uninstall Microsoft ACPI compatible with battery control method... In fact, uninstall all you can under the batteries, but that should be all there is. It will be re - install when starting... Stop cell phone... Remove the AC adapter / CC... Replace the battery... Plug the power adapter... Start the laptop... Now, everything should be good.

  • Tecra M10 - Sound does not work on Windows XP SP3

    TECRA M10 sound does not work with Win XP SP3

    1. the drivers from the toshiba web site.
    2 chipset drivers and audio drivers were reinstalled no luck,.
    3. no mute FN + Esc
    4. feature eat that all drivers ok


    If I understand your right all devices listed correctly in the Device Manager and you don t have yellow exclamation points?

    Normally, for high definition sound cards, you need two patches from Microsoft:
    KB835221 and KB888111.
    Normally, these patches are integrated into SP3 but it works only if you install the audio driver after SP3. So, if you have an older version of XP without SP3, you must update to SP3, all first and then install the display driver.

    So in your case, you must delete the current sound driver and restart the laptop. Then use CCleaner to clean the registry and system files. Reboot the laptop. Then download and install the driver of his newest Realtek Hompage.

    Good bye

  • Re: Sound does not work on Tecra M10

    Hi all

    I have a Tecra M10 with XP and all the drivers installed, but sound does not work.

    I checked the Device Manager and everything is fine, no red cross or whatever it is on the driver realtek audio.

    Everything on the sound properties. I even uninstalled and downloaded the audio driver from the toshiba site again but still no sound and no mistake.
    Can someone help out here?

    Thank you.


    The sound is turned off on your laptop? With the FN + ESC key combination you can enable/disable it.
    Check it!

    In addition to the high definition audio devices you need two patches from Microsoft to go looking for the proper functioning. Have you installed the two?
    Here are the links to the Microsoft Knowledge Base where you can download both:

    Good bye

  • Satellite L30: The sound does not work on XP Sp2

    Hi, sorry but I cannot well English.

    I have a problem. I do not have CD with drivers, but I download from the toshiba site.

    Yesterday, I reinstal windows, then I install all the drivers and I have a problem with the audio drivers.
    In Device Manager is all good, his system is activated, drivers of instalation, I have no problem. But sound does not work.

    You have any ideas?


    If the sound does not appear on your laptop, you must first check the volume control on the side of the laptop. Turn it up to the max level.
    Then check the sound devices and audio in the control panel if any controller is disabled or turned to the lower floor.

    Additional connect headphones and check if you can hear something.

    By the way: have you installed the correct drivers? On the Toshiba page, you will find two different sets of portable Satellite L30

    Any tip?
    [email protected]

    First check the status of the sound card in Device Manager.
    If there is a yellow climbing brand then you should try to reinstall the driver. (first remove it and after reboot, install a new)

    Have you checked the volume setting and the site of laptop? Eventually he s a very simple idea, but believe me, I read many comments here in the forum and a lot of guys forget this option simply.

  • Satellite L655 - sound does not work on the new install of Windows 7 Pro x 64

    Howdy all,

    I bought a Newegg L655-S5111, which was on sale, put an SSD, and then installed a legitimate copy of Windows 7 Professional 64 - bit, I got from my current employer (I'm a computer scientist). I've updated to the latest revision of the BIOS (1.70), and I have all the updates installed Windows, all drivers installed, including the correct drivers Conexant HD Audio and ATI HDMI Audio. Unfortunately, the sound does not work. Sound works briefly during my first install of Windows 7, then I cut it up until I could get it set up with a helmet. When I disabled it, she had stopped working.

    This laptop is less than 3 weeks at this point, old and I get no audio on headphones or speakers, even if Windows displays clearly no problems with the drivers, they have the latest version on a new installation, and I can see the audio mixer game. The laptop built-in microphone captures sound as well. I think that's probably not a matter of the physical interconnection, but more likely a software problem, I just have trouble identifying where it is.

    I have also no related error message than any where in the case of newspapers.

    Can you please do a test and install original recovery image Toshiba, that you got with your laptop on this new SSD, just to see if it will work with the original image.

    Recovery image contains all the necessary drivers and OS is perfectly configured so each piece of hardware in your laptop should work correctly.

  • Sometimes sound does not work on Satellite A65

    I got my pc for years and never had this problem until recently.
    Most of the time the sound does not work, but sometimes when I restart (and sometimes when I'm warming up stand-by) the sound will return.

    When it works it lasts as long as the PC is on, but it the PC itself will be down due to overheating sometimes, and even if it does not, I do not leave all the time.

    When the sound does not work I can not play with the exception of windows media videos.
    Any youtube or videos of the similar site will only play for about two seconds and then pause, no noise at all.
    Same thing for my iTunes.

    When the sound does not work I can play iTunes all night, but when it isn't the songs does not play again. The cursor remains just at 0:00.

    Is there something I can do?


    As a first step, the fact is that this laptop is pretty old. I think around 4 years. Am I right about that? There may be a lot of dust on the inside and as a result you have it sometimes overheat issue. May be time to clean the laptop.

    If is also possible through these overheating problems is something faulty now. It may be that some contacts (associated sounds) are not much more and the contact is it sporadically. To be honest, to me that sounds like hardware related issue. I really don't think you can do much alone. Maybe try to make clean OS install and see what happens. If the problem persists or you have to get an external solution or takes it to the authorized service provider.
