T420s 4174-fm9

I have no function in my speaker volume button, what driver should I install?

Then I have pci serial port and USB controller driver missing in the properties of the computer...?

And in addition a specific driver missing?

I installed this one: Hotkey integration of features for Windows 7 (32 bit, 64 bit), Vista (32 bit, 64 bit), XP (32-bit, 64-bit) and 2000 - ThinkPad

  • T420s external microphone does not work

    I just bought a T420s, 4174-P5G Type, I want to use an external stereo microphone (Sony ECM-719) rather than the built-in microphone, but as soon as I plug the combined headphone/microphone jack, the microphone is recognized as helmet. Anyone has an idea how to do the external microphone works?

    The sound card is named 'Conexant HD SmartAudio 20672' and I think that I have the latest version of the driver installed correctly.

  • URGENT: T420s BIOS v1.29 and PGP Whole Disk Encryption

    ATTENTION!

    I have several portable T420s (4174-2AU). I recently upgraded to 2 of these phones to the latest version of the BIOS (v1.29). These two laptops were more able to access the encrypted drive.

    -----------------------------------------------------------

    BootGuard stage2...

    PGPWDE disk data is corrupt...

    system stopped...

    ----------------------------------------------------------

    My company does not recovery discs, for what reason I don't know. All I know is that I had to reimage the readers. I have tried to quantify again and restarted and received the same error again. So I reconfigured again and has not encrypt the drive. Others say it has to do with the PGP and the Sandy Bridge architecture, but I disagree. I could populate the BIOS with Lenovo's FLASH tools. I descended to v1.25 (download) and THEN encrypted the drive again. After the reboot, there is no problem.

    I hope that no one else has this problem. If you do, here is your solution.

  • How can I confirm that my T420 is updated after a fresh installed win7

    Hi all

    Well, as the title says, I just bought a T420 and installed a new SSD. Then, I installed win 7 and managed to get the other drivers from the support page for driver lenovo than win 7 didn't pick up. However, I know there are updates driver and/or utilities lenovo I should put to day and so I was wondering what is the best way to confirm that my system works the latest revisions of drivers/firmwae/bios/utilities... without adding utilities bloatwhare.

    I noticed there is a Thinkvantage utility, which is useful

    Thank you

    Derek

    Good day and welcome to the community.

    Not sure that Thinkvantage 'utility' that you see, but if it's SystemUpdate, then Yes, it is useful for what you hope to accomplish.

    Please see: http://support.lenovo.com/us/en/products/Laptops-and-netbooks/ThinkPad-T-Series-laptops/ThinkPad-T42... for the latest version.

  • Incompatible Audio volume T420 - Audio problem.

    Hi all

    recently I've been an audio problem with my T420. It doesn't matter if I use the built-in speakers or an external playback via the audio device, audio volume goes up and down several times for a minute.

    It's rather annoying and irritating. I use the standard driver provided by Lenovo and with stock settings.

    If someone had this problem and could give me some advice?

    Thank you very much!

    The framework was already to the people with reduced mobility.

    I thought, maybe that's the problem, I've been experience, because it is only when I used Ethernet instead of WiFi: DPC latency + audio / mouse skip and stutter on t420--Lenovo's community

    I tried the proposed parameters, without success.

    Interestingly, re - install the same drivers that have been installed previously seems to have solved the problem.

    Maybe some settings or installation screwed up.

  • T420 & Windows 8 questions.

    Greetings to the community.

    I would write some of the issues I'm facing after installing windows 8 on my T420.

    I bought the laptop in August with windows 7... then somewhere around early November, I upgraded to Windows 8.

    I met other threads that directed me to the updates for windows 8. I installed everything I could find for windows 8.

    However, the following issues still remain.

    1 micro button mute does not work.
    2 Fn + F2 does not work

    3 Fn + F3 does not work

    4 Fn + F5 does not work

    5 Fn + F6 does not work

    6 Fn + F8 does not work

    7 Fn + PrtSc doesn't work

    8 Bluetooth remains on all the time with no way to disable the right click. Yesterday I downloaded an update through the update of the system for the bluetooth, but the problem remains.

    9 Thinkvantage does nothing.

    Could someone help me identify what might cause these problems and how I could find a solution for the same?

    Any help with much appreciated!

    Thank you.

  • The upgrade of the card Wifi in T420s AC

    I think the upgrade of my wireless card Intel AC card.

    As far as I understand there is a white list of BIOS for the authorized material that will require flashing before you install anything with non - Lenovo FRU. As I have not been able to find a card that is dealt with by Lenovo, I don't really see option to blink.

    Could someone point me in the direction of a work card, or a mod of BIOS work? I thought the 7260 Intel as a replacement card.

    Did anyone done this before? :-)

    Welcome to the forum!

    There is no wireless card out-of-the-box-work AC for a T420, so looking for a mod of BIOS.

    There are places online that specialize in the provision of modded bios, I doubt anyone here will post a direct link with one of them on Lenovo's own forum.

    Time to put the search engine of your choice to work.

    Good luck.

  • T420 driver windows problem 10

    Hello

    I have ThinkPad T420.

    Could someone help to find the drivers for these devics:

    (1) USB\VID_0BDB & PID_1911 & REV_0000

    (2) VEN_1180 & DEV_E823 & SUBSYS_21CE17AA & REV_05 PCI

    (3) PCI VEN_8086 & DEV_1C3D & SUBSYS_21CE17AA & REV_04

    I just upgraded to 10 Windows, and I can't find these drivers. There is no drivers for Windows 10 on the support page. I tried to use the lenovo system update, but completely the thing it installs is "dependence of the device.

    Best regards.

    1. There is no driver win10 of Ericsson and Lenovo for the F5521gw. And most likely will be unavailable again.

    Therefore, to use drivers win7 in compatibility mode, there are mentions on the success on the forum (probably, win8.1 drivers work also).

    Install the drivers in the folder where the drivers package is extracted to launch the following string:
    Setup.exe /wNOAUTOSENSING /wUSELASTKNOWNRADIOSTATE

    2, 3. As you understand, drivers Intel MEI and Ricoh are needed.

    I know of cases successful on ThinkPad Laptops, the SandyBridge-based (as T420) and the upgrade of win10, without problems, using built-in win10 drivers only, and not from Lenovo or components manufacturers. Unfortunately, currently ms update catalog does not load the drivers of their identity documents, because of the error appears.
    So, I can not explain the cause of problem of drivers.

    Finally, I didn't check whether the Ricoh site related win10 drivers.

  • T420 graphic card appearing does not

    Hi, I have a T420 that I recently bought, and the seller said that the computer comes with a

    NVIDIA NVS 4200 M graphics card. And no matter what I try I can't find anywhere.

    I went through:

    Device Manager

    CPUID HWMonitor

    BIOS (no mention of switchable graphics anywhere, or even mention of video anywhere.)

    I have downloaded the nvidia driver and he said that he could not find compatible graphics hardware.

    As silly as it sounds I only bought this computer due to his condition and does, it came with a graphics card.

    The model number is 4180-CP1, I checked the drivers for the model, and it is said there are available for laptop nvidia drivers. It is in very good condition so I don't think that the card can be fried, but I don't know what to do to get it activated. I've already updated the bios and nothing seems to have changed. (Through the lenovo update tool)

    I really need to understand this because otherwise I have return the computer and that will cost me much!

  • Power Manager 8 (.1) T420 and windows

    As a user of two years of the T420, I'm pretty used to the Manager of power and its extended options. When I tried Windows 8 a a few months I noticed that there are only standard electric Windows Management options available. Mind you, it has worked well, but they were not nearly as good as the power manager Lenovo.

    My question is whether or not this (Power Manager) feature is available for windows 8 (.1) or will be available in the future?

    There is no ThinkVantage Power Manager for Windows 8.

    Power Plans and slow down timers are managed by the operating system itself.

    Lenovo power options such as battery Stretch and 30 days of standby can be configured in the settings of Lenovo.

    What specific feature of Power Manager you think you miss on Win8?

    Greetings!

    I'm probably not the first person who cares, but I did not find the same topic in the forum.

    I have T420s Lenovo ThinkPad Mini Dock Plus Series 3 with USB 3.0 plugged 90W. The problem, I USB 3.0 port on the dock (blue) work in USB 2.0. The port of the laptop works very well. I check it by plugging Seagate drive HARD mobile - when the HARD drive is plugged into the port blue station dock Windows (7, 64-bit) complains "device can run faster", using the port laptop does not trigger the message.

    USB 3.0 is installed.

    BIOS version is 1.37.

    Drivers Intel Chipset are updated.

    Device Manager displays the connection as a chain of two "Generic USB Hub, if the HARD drive is connected to the laptop port its chain of" Renesas Electronics USB 3.0 blah - blah ".»

    Help, please! If this combination is not supported, please point to the corresponding link.

    Thank you!

    USB 3.0 port on the dock is not supported on the T420s, it is supported only on T430s and later versions.
