Lenovo X1 Carbon Mute Button - Win 7

Hi All My x1 Carbon came with Windows 8 pre-installed; however, I found it horrible and such I reinstalled Windows 7 64Bit (Personal Copy). After spending hours trying to download all the drives, I downloaded system update and it seemed to install 100% of them for me; however, the mute button does not work. If I press the mute button nothing happens, nor does the little LED light up. I have installed all Lenovo drivers under the sun, including the hot-button one; however, I still cannot get it to work. The Mute Microphone next to it works fine; however, not the mute speakers. The strange thing is that the Mute Speakers LED lights up during Boot (BIOS Screen) so its obviously working. Does anyone have any advice? I have a Late 2012 model - 3443-CTO Thanks!

Check out this link... http://windowsvc.com/bbs/board.php?bo_table=windowsvc&wr_id=2160 I deleted the service and then installed the hot key driver from the lenovo support site, and it put it back. My issue was exactly the opposite. By executing the above it left me with exactly the same issue I already had. My mute button turns itself on all by itself. I turn it off by pressing the mute button, and it goes back on all by itself! Think Lenovo has issues with its software. Called Lenovo support and after they tried a few things suggested I send the laptop in for repair/replacement. Anyway, check to see if this service is running, maybe this will help. My laptop is a a model 20BS X1 Carbon. Thanks.

T500 mute button and OSD not working

Hi. I'm having a problem after upgrading my t500 to windows 7 ultimate 64bit.
The volume buttons work fine (even without the hotkey software installed), but the mute button and the on screen display doen't work.
While I can live without the OSD, the lack of a mute button is really bothering me.
I have the power manager installed as well as the hotkey software. not sure if this has anything to do with it but UltraNav is also installed.
No idea where to go from here so I'd appreciate any help the community can provide.
Solved!

I was having similar problems with some R500's and so I did some research, and came across the following, as mentioned in:
http://forums.lenovo.com/t5/Windows-8-and-8-1/ThinkPad-On-Screen-Display-hotkeys-for-older-systems-T...
“To make OSD work, you might need to install Hotkey driver and Microsoft Visual C++ 2010 Redistributable Package.
To test if this is your issue, run C:\DRIVERS\HOTKEY\OSD\tposdsvc.exe and see if it complains that msvcr100.dll is missing. If it does, install Visual C++ and it should work after that.”
What is not said, but what is critical, is that you have to install the 32 bit version of the Microsoft Visual C++ 2010 Redistributable Package, even on a 64 bit version of Windows 7 Professional.
You then have to reboot the computer after the install for the change to take effect.

Satellite A660: Remark and a question about illumination/mute button

Remark:
Hi, I am a proud owner of a satellite A660-166 (3 days old) and I installed everything from scratch on the win 7 pro since I received my laptop with a home version (need pro for work)...I encountered some problems but this forum really answered all my questions :) Never found such a helpful forum for technical support. So I wanted to express my gratitude and my support for everything you do for the users :)
Problem: Well, it's not really a problem, more of a curiosity... I had some problems with the eco button at that point illumination/mute button was for mute....Thanks to you guys I found out what needed to be done, I reinstalled Flash card software and everything was working properly plus the illumination/mute button was for illumination now. I don't have anything against that, I prefer it that way, but I'm wondering how do I change that...I found some unanswered thread about using toshiba assistant and the illumination tab...Since my laptop is pretty new, I don't have an illumination tab, I was wondering how do I change the button to mute if I want to?
Thanks, keep up the good work!

It is nice to hear you found answers to your questions here. Many people here try to help.
Back to your issue: It is not easy to offer precise answer and I really dont know if you can change settings for one single button. I think it has something to do with registry entries but how to change it is another question.
If you use this button for illumination ON/OFF you can use FN+ESC for MUTE option so you will have both options that can be used using one single button or quick key combination.
Can you please test it and confirm it works properly?

Volume buttons and mute button don't function in Windows 8 64-bit

Almost funny, I also have installed Windows 8 64-bit on my ThionkPad SL500 (clean install). I have read other people complaining about "Volume buttons and mute button don't function". This is exactly the same problem I have. I have found no exact procedure about what software to install to make this work. Instead people refer to other threads that often end in some desert... So, does anyone (Lenovo?) have a clear answer on what software to install (and links to those drivers please...) :-? And, yes, I have tried installing different software packages by following threads, but nothing has worked just yet... So, clear instructions / links, please :-)
Thanks,
Niels

I recently found this information on the micorsoft troubleshooting website and thought of your post, not sure if you had found a solution but hopefully it is helpful.
My keyboard volume controls suddenly stopped working
If the volume controls on your keyboard stops working, check the Human Interface Device Access service on your computer to make sure it is set to Automatic.
In the Start menu, type View local services.
From the Search Results list, select View local services.
In the Services dialog box, locate Human Interface Device Access. Make sure the status is set to “Started.” If it is not started, click Start the service.
Right-click Human Interface Device Access and select Properties.
On the General tab, in the Startup type, select Automatic, and then click OK.
Thank you for being a part of the Lenovo Family,

ThinkPad Hotkey Features Integration 3.89.0000 On Screen Display and Mute Button Fail

I am installing updates on a T400 system running WIndows 7 Pro 64-bit.
The system has been freshly factory restored and all features work properly...
After running System Restore to update to the latest drivers and recommended software, I find Thinkpad Hotkey Features Integration 3.89.0000 breaks features.
I am able to use Hotkeys to change brightness up/down, Fn+F5, Fn+F6, etc. The volume up and down keys work to change volume. The mute button does not work at all! There is no On Screen Display to show the adjustment settings for any Hotkeys.
I have found that installing the older 3.88.0000 (8jvu40ww.exe) version of ThinkPad Hotkey Features Integration works successfully with mute button functionality as well as the On Screen Display features.
Comparing what is different between the 3.89.0000 and 3.88.0000 versions, I find On Screen Display version and Full Screen Magnifier have advanced. The version information table at the bottom of the software download page is inconsistent compared to what is actually reported from the 3.88.0000 setup.exe:
Setup shows:
On Screen Display 6.71.00
Full Screen Magnifier 2.40
The table shows:
On Screen Display 6.72.00
Full Screen Magnifier 2.41
The System Interface Driver is 1.05 on all the recent versions.
With the 3.89.0000 version installed, I cannot uninstall and go back to the older version to get it working. Instead, I have to do a System Restore to a point previous to the newest install... something changes in the new version but I am not yet sure what.
I have no warranty on this system. Lenovo technical support is unwilling to entertain a conversation about solving this issue with their software unless I purchase a support package. Perhaps someone from Lenovo reads this forum and/or one of the community members has a contact or option so that I may report the issue to those who are responsible for resolving Lenovo software issues. I am hopeful they can solve it in their next release so that I do not have to hide the current version from System Update.
If anyone has ideas on what causes the latest On Screen Display or Full Screen Magnifier to disable the mute button and prevent On Screen Display from working... I would love to try and solve that problem. Additionally, if you have ideas on what prevents uninstalling and going back to an older version, that would also be helpful as I would not like to rely on System Restore.
If there is no solution other than to avoid 3.89.0000 it is what I will do and this message will help others so they do not spend hours to confirm the issue is with the 3.89.0000 version rather than suspecting hardware issues.
trying to figure out the source of the trouble.
Thank goodness Lenovo offers previous versions in a table at the bottom of the pages so we can try older versions and go back to what works. It is a shame they do not advertise a link or other option to report bugs and issues with Lenovo software/drivers directly.

This is the roulette you play with updating functions that are already working properly.
If it's not broken, don't fix it. Do the release notes describe a fix or enhancement that you want? No? Then leave it alone. Hiding updates in Lenovo Update is the easiest solution. For RChesley, in this case.
Bob, I realize that you want the function that the update is supposed to deliver, but the update has failed you. It's like installing version 1.0.0 of software sometimes, with Lenovo Update. You're never quite sure what you're going to get. There's tons of posts here that read as though the users are beta testers--installing updates and finding the bugs! So the developers can go back to the code and try again.
I've learned to never be an early adopter here.

HP Probook 4520s: sound card doesn't work (no sound, red mute button)

Нello!
I have an issue with my HP Probook 4520s. Its internal speakers and microphone doesn't work. I've tried to install and reinstall drivers from here, tried to rollback driver to older version but I always have the same result: installed the IDT sound codec, and after a restart, the mute button turned red and I cannot switch it.
Soundcard device ID: HDAUDIO\FUNK_01&VEN_111&DEV_7605
OS: Windows 7 Professional x86
How can I fix it?

Hi, just registered to post my solution. I got HP ProBook 4330s in for repair. Problem: some sticky liquid spilled all over and no sound. Also discovered that no microphone as well, but webcam did work just fine.
What I tried:
1) Installed fresh Win 7 Ultimate 32-bit and all official drivers (audio driver did not want to install), still no sound. Sound icon shows red cross. Message: No audio output device installed.
1) Installed the newest version of BIOS, in my case F.40, still no sound.
2) Pluged in headphones, still no sound.
3) Took apart, unpluged and firmly inserted every possbile cable, still no sound.
4) Found in BIOS everything that relates to Audio. Made sure Audio device is enable, still no sound.
5) Install XP and installed XP sound driver, still no sound. In fact, that driver did not install correctly, showed some kind of error.
What did work, in consecutive order:
1) Took apart again and took out the coin battery that retains the BIOS data, date, clock etc.
2) Put everything back together, switched on, entered the correct date in BIOS settings, and started Win 7 Ultimate. Still no sound. But I noticed that Win 7 Ultimate has found some devices and was installing drivers for it. Though did not check exactly which ones.
3) If I could not get the sound working I was determined to buy some speakers with USB connection. Then, I remembered that I already had a set of speakers for another laptop. These speakers had USB connection to draw power from and a grean standard headphone connection/plug to draw audio signal. I plugged in these speakers into HP 4330s and the sound started coming from these external speakers. The sound icon next to the clock in bottom right corner switched to normal mode and I could control volume with my mouse. Then I unpluged external USB speakers and the sound started coming from the HP's built in speakers.
Checked with Device Manager that correct sound drivers are installed and microhpone appeared to be installed as well. Though did not check with Skype if microhpone was working.
I was soooo happy!!! I struggled with this problem for three long days, searched many forums (none gave solution), tried everything with drivers, took apart the laptop some three or four times (now I learned to do it with my eyes closed, so to speak).
I started to think that taking out the BIOS/date coin battery did the trick. There must be some glitch in BIOS to motherboard connection in these HP ProBook laptops, and all BIOS settings need to be reset.
I'll be happy if this helps someone.

Mute button on V570 with WIndows 7?

I just purchased a Lenovo V570 with WIndows 7. One thing I don't see is a mute button. Is there such a thing? Or a shortcut?
Any help is appreciated.

there's none.

T420 Mute button queues up unnaceptable amount of Kernel work

FAO someone from Lenovo - for the Driver dev team.
To reproduce:
Download DPC Latency Checker or LatencyMon
Run either utility
Hit the Hardware mute button on the T420.
Watch the DPC Latency Spike to around 4000 micro seconds. Same applies when unmuting. Also occurs when using windows mute option, because it lights up/turns off the hardware mute internal led.
I fail to understand why the hardware driver (simple HID device) needs to queue kernel work like this, it's a simple command that can be implemented using an inverted call pattern to tell other user mode programs (such as the on screen drawing device) that it was successful.
The Windows Driver Development Guidelines state that queued work should take no more than 100 micro seconds.
If someone (ideally a Lenovo driver dev) could pick this up that would be great. Thanks.

Confirm on W520, except around 8000 microseconds.
Could it be scaling with respect to visible core count? (T420 at 4, W520 at 8.)

HP Probook 455 G1 dts+ audio software & mute button light change missing on Windows 10

Dear Support! I upgraded my probook from win 8.1 to win 10 home and i have a few problems in relation with the audio. 1. In win 8.1 the audio driver has a dts+ software (if i remember good for the name) which can optimize the sound with effects and eq etc. The notebook sounds good with this but in windows 10 i can get this and the quality of the sound is much worse. In addition in the device manager on win 8.1 the audio card names as IDT High Definiton audio but in win 10 it is "High Definition Audio Device". I don't know whethet that matters. (also has an amd high definition audio device, but if i know good its the hdmi audio) So I want to ask how can i get this to win10. 2. The audio mute button in win 10 doesnt change color -the wifi button does it- from white to orange if there is a change. The funcionality is working so it mutes the sound. So i would like to get some solutions about that, i tried to download drivers from hp support but i didnt see anything for this. Thank you for your answers, Akos ConfigHP Probook 455 G1 with AMD A10-5750M APU

Everything i need is the driver from the win 8.1, i can't believe nobody from HP can help me in this.......

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp56501-57000/sp56717.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, restart the notebook and let Windows fully load. Open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, restart the notebook again.
Regards,
DP-K

I don't have any volume. When I push the mute button or try to increase the volume up or down nothing happens. The volume shows up as if it were at full volume but no sound. I am so frustrated.

I need some help with the volume on my macbook pro. I am getting absolutely no sound no matter if I push the volume increase or decrease button. Nothing changes. The volume bar shows up as if it were at full volume but no sound and the mute button doesn't do anything either.
Please help.

Go step by step and test.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers.
    Make sure that Mute is not enabled.
2.Plug in and remove the headphone.
    If you see red light in the headphone port or not, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
    Try this even if you don’t see the red light.
3. Reset PRAM. http://support.apple.com/kb/PH14222
4. Reset SMC.     http://support.apple.com/kb/HT3964

5. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
