Mute witness keyboard stays on

Hello:

Pavilion DV7-4270us

Windows 7 64 bit

The mute button on the keyboard remains orange/red all the time, even if the sound is not muted.

This seemed to happen around the time I installed a replacement hard drive.

Any suggestions to fix this?

Thank you

Hello

Line mute functionality is provided by the audio driver, then try the following.

Download IDT Audio Installer on the link below and save it in your downloads folder.

http://ftp.HP.com/pub/SoftPaq/sp50501-51000/sp50595.exe

One time finished, open windows control panel, open Device Manager and open sound, video and game controllers.  Right click on the IDT device and select uninstall - also, you should get a command prompt to delete the current driver, check the box allow this and then proceed to uninstall.

When you're done, shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

Allow Windows to fully - charge it will automatically load an audio driver, but let just this complete.  Then open your download folder, right-click on the IDT Installer and select "Run as Administrator" to launch the installation.  Once this done, do a right-click the speaker icon in the taskbar and select playback devices.  'Speakers and headphones' left click once to highlight, and then click the Set Default button - restart the computer again.

Kind regards

  • Mute button external does not turn off

    Hello

    OK, let's try another driver and a slightly different method.  Download the following Installer and save it on your desktop.

    IDT Audio Installer

    Once download completed, right click on the installer and select "Run as Administrator" to launch the installation - ignore any warnings that you have already installed a driver later, just continue to install it.  When finished, restart the computer and check the status of the IDT audio device in Device Manager and let me know.

  • Illumination of the keyboard blackBerry Smartphones

    Go to OPTIONS, SCREEN/KEYBOARD and then switch the auto backlight on OFF Dim.  You keyboard stays on for the time that you set in seconds for her to stay, RATHER than DIMMING.

    The brightness of the screen is also controlled by adjsuting on the same screen in SCREEN BIGHTNESS

    HEY... I was jut wondering... is it possible to keep so the keyboard STAYS on? What is happening with the light... I do not understand it :/ I just got it, so if there is a way if you could tell me how! Thank you

    Options > keyboard/screen, you can set the timeout on a time defined.

  • Keyboard does not close and loses the connection.

    Hi guys,.

    Having a problem at the time with input boxes and the keyboard to phonegap. the issue appears only on apple devices. It is very well on Android. We get an application of simple connection with two input fields:

    IMG_0013[1].PNG

    Now, when we enter a correct user name and password, the keyboard disappears and the app moves on. The quirk seems to be when using incorrect credentials. The keyboard stays on the screen and the cursor remains in the last box you typed in. However, by pressing the keys on the keyboard has no effect on the box. By selecting other credentials of entry also has the same effect. You must close the manually close the keyboard and press again on one of the boxes.

    I have tested on several iPhones and iPads with the same effect. When I run the site directly into a browser rather than through phonegap, it works as expected; The keyboard closes and an error message is displayed. I tried calling blur() on entry on touchstart and touchstart event fields and tried focusing on the button "login" during the presentation, but they seem to have no effect.

    Anyone seen this before? If you need more info let me know.

    Thank you

    James

    I have to guess here:

    -It really has nothing to do with the "evil powers". It's how you manage the entry that does not have the keyboard disappear (again)

    -a page switch, the keyboard will disappear

    -I guess the keyboard also disappears when the form is submitted, but not (yet) on the touchstart event

    Then; I suggest catch you to the event of the form, then use ajax to send data to the server.

  • PS CC blocks keyboard

    A new one on me - after that using PS CC for some minutes the keyboard hangs. I am still able to use pointing devices and press enter, but all the other keys will stop working. Interestingly, my keyboard lights up and has some idle time seconds, after which the backlight fades. When the keypad is locked, the keyboard stays on. If I try to use the keyboard with other programs, it is also not functional until I close PS keyboard then normal operation is restored.

    I googled this and reported that another person the same phenomenon, using a Mac. I'm on a PC running Win 7 Pro. Someone at - he no clue as to what could be causing this? I obviously can't be restarted PS every five minutes, especially given that as a result, it is impossible to save any open files.

    TIA,

    Photoshop does not affect the keyboard - Photoshop knows nothing on your keyboard, or the driver for your keyboard.

    Photoshop becomes just the key events of the BONE (which leads them from the driver).

  • rMBP 2015 freeze, black screen and reboot (Journal of kernel panic)

    Hello

    For the last few weeks, I had a big problem with my rMBP 2015. Mac suddenly freezes and is not responding and I have to hard reboot (hold the power button / stop). The last time I waited a few minutes without reboot and the screen went black (keyboard stays on) and then it restarted. I received the error log after this: http://pastebin.com/XzR8BPdE.

    I tried reseting PRAM, NVRAM, MSC, repair SSD in disk utility and repair permissions and about every 24 hours the same permission error occurred: http://pastebin.com/ZG1D1F4N. After repair of permissions that freezing problem seems to be solved, bot after another (approximately), he repeats, so it seems to be unrelated to the problem.

    Apple diagnostic shows PPT004, but not all the time.

    These gels seem to be completely random, but they occur every day one/two. It happened a few times when the briefing notice, once when I was cloning disks CarbonCopyCloner and some other situations. I would be really grateful for help or any way to fix this. I have warranty still, but I need to use my Mac, so not bring for repair would be ideal.

    I did the fresh install with Time Machine backup system after about two months ago.

    The panic is caused by a kernel bug. Please disable the firewall in the security & privacy preferences window and see if the panic stop.

  • Equium A60-157: random alphanumeric characters

    Thank you very much.

    Hello

    Well, I m not 100% sure, but it could be an unstable cable or something wrong wit keyboard connectors.
    In this case, I recommend to ask the service partner Toshiba for a diagnostic test.
    I m sure it can give you correct information on fault.

  • HP Probook 450 G1; E9Y30EA #ABB: [Windows 10]: driver compatibility problems, sound buttons do not work

    Hi all

    I recently did a clean install of Windows 10 x 64 on my HP Probook 450 G1 (E9Y30EA), and after installing the drivers I noticed when I cut the sound, my Mute button will not change its amber color (or orange, yellow, regardless), as it did in Windows 7 and 8.1.

    In addition, another thing that does not work is shortened mute Microphone keyboard (fn + F8). It turns off the microphone, nor its LED lights.

    I have the latest version of the Support of hotkey driver installed (7.0.13.1) HP, HP Quick Launch Buttons, HP wireless button, installed, .NET Frameworks 2.0 and 3.0, etc... everything is up-to-date, but it still not working as it should. Micro just cut does not work and pressing (sound) Mute button mute, but its light remains white, so I often do not know if I got the sound we or off with the look of a look I did.

    On the other hand, HP wireless button works normally, and it changes color to Amber when I press on it to activate airplane Mode.

    TL; DR: After the installation of the Win10 Hotkey Mute Microphone work and his Mute button works, but the LED does not work.

    Is what I can do to fix that, or is this just a problem with the driver incompatibility which would be fixed in some future updates? Or it is something else, like Windows 10 question or maybe audio driver?

    Thanks in advance,

    W 8.1 IDT AUDIO driver was a solution for me. All the buttons work now.  HP should release W10 audio driver for this problem, as the wrong audio driver provided by W10 is a reason for this problem I think.

  • impossible to reinstall windows XP pro...

    Hi, I'm hoping there's an Assistant "you have not" reading of this...

    I got tired of random programs from decide who wanted not run/open/work at all without reason aparant, some viruses of compensation or foolishly setting set somewhere im enough computer but I have the wrost chance in the known universe.

    sort of, I'm so fed up with progs (Itunes 10, steam and a few others which im not to bothered all) does not work after reinstalling and ask questions on the support pages (no awnsers), I went to my irritable Local store "Yet-to-be-tamed" and am myself a Xp pro SP2 boot disk, I bung inside as he told me how to "repair" Reinstall if I lose any data/settings (I wondered weather it is possible but what _ I'l give it a shot.) So I stuck the cd player, auto run, I chose the installer of windows... a black magic happened, an error that happened (sorry I forgot what he said... no doubt VERY important, something put in shape) I click ok... He continues... cool it restarts... running the ASUS... What ever, it's that I had with the MB, entry of the Os, POST Hits startup boot screen... Then the Group of experts of vacuum... not even a mouse... the screen remains black keyboard stays on... CD player still spinning... nothing... then a new sound arrives, a little like a horn noise sounds / burrr dissaproval. I can enter the place of startup parameters (forget his name) and allso I can't enter the menu "what do you start from", but none or the start device setting will get me anywhere. This have on earth I did... that is why I hope that there is a reading assistant.

    Oh allso not even invite him "press a key to continue."

    I searched on google for about 3 hours... try each veriation of 'I failed to reinstall win xp pro' I think.

    I gave up with the Go how ever many music... game saves, docs edited, all, I fortunately will wipe away everything just to get it working again. I don't just save my data any more, if I can save is great, but I'm not going to be bothered if I lose everything...

    I'll pop in my shop techy "yet to be tamed" and beg you to help me.

    but for the time being. you guys will have to put up with me for abit.
