ThinkPad x240 missing drivers

Hello! I've recently installed Windows 8.1 on my new ThinkPad x240 and I've been looking for certain missing drivers ... Those devices are marked as "Unknown" by the device manager and the drivers are most probably not downloadable from the lenovo driver matrix (because I downloaded & installed all relevant). The Lenovo Solution Center nor the System Update can find anything ... The hardware IDs are as follows:1st device:USB\VID_138A&PID_0017&REV_0078
USB\VID_138A&PID_0017 2nd device:ACPI\VEN_INT&DEV_33A0
ACPI\INT33A0
*INT33A0 3rd device:ACPI\VEN_INT&DEV_340F
ACPI\INT340F
*INT340F 4th device:PCI\VEN_8086&DEV_9C3A&SUBSYS_221417AA&REV_04
PCI\VEN_8086&DEV_9C3A&SUBSYS_221417AA
PCI\VEN_8086&DEV_9C3A&CC_078000
PCI\VEN_8086&DEV_9C3A&CC_0780 5th device:PCI\VEN_10EC&DEV_5227&SUBSYS_221417AA&REV_01
PCI\VEN_10EC&DEV_5227&SUBSYS_221417AA
PCI\VEN_10EC&DEV_5227&CC_FF0000
PCI\VEN_10EC&DEV_5227&CC_FF00 Do you know, what kind of hardware that might be and where can I get the drivers? Thank you!

Hello,
Unsure about the first device.
Second device appears like it might be the iSCT ACPI Virtual Device.
Third device appears to be the Intel Collaborative Processor Performance Control Driver.
Fourth device appears to be the Intel Dynamic Platform & Thermal Framework Driver.
Fifth deviceappears to be Realtek RTS522x PCIE Card Reader Driver.
Since none of these drivers are specifically for your model of ThinkPad, and appear to be for Windows 8.0, not 8.1, I would advise some caution when installing them.  At the very least, perform a backup of any valuable data
Alternatively, wait until Lenovo officially releases Windows 8.1 compatible computers and begins supporting it, and then install the drivers qualified for your operating system.
Regards,
Aryeh Goretsky

  • ThinkPad X240 missing WLAN drivers on Windows 7 64bit Enterprise

    Hi,
    I got first X240 to our company. I have had serious problems to install drivers into operating system. All Windows updates are up to date, thinkvantage system update has been run numerous times. Unfortunately, I had to install all thinkvantage programs manually as well as drivers. Now there is one particular unknown device listed in device manager. I have downloaded and installed the right Thinpad wlan driver from the drivers section for x240. I have still problems to get wlan controller identified by Windows 7. I have also tried to install those drivers manually. I am starting to wonder that there is something wrong with the drivers or the hardware itself. I have installed around 450+ Lenovo Thinkpads during my career. Any suggestions? Is there known issue with the x240 wlan controller driver?
    Thanks in advance.
    Solved!

    Hi Supre5,
    Apologizing for the inconvenience caused. Could you please try installing this Intel Wireless LAN driver?
    Else, try running Intel Driver update utility which auto detects the relevant drivers for your system and install it.
    Hope this helps!

  • How To: Debug missing Drivers in MDT

    The definitive post on missing drivers in MDT (most comprehensive list I've done so far)…
    Please to NOT post questions from this thread, instead create a new thread.
    How to debug Network Driver Problems
    One of the earliest hurdles an MDT administrator will come across is the management of device drivers, specifically networking drivers. With most other drivers, like Audio, printer, and video drivers, a quick call to Windows Update or install over the network
    will resolve the Installation. However unless the Network (and storage) Drivers are installed into Windows from the start, it will be much more difficult to install the rest of the system.
    This post should help you get started if you find a machine that did not install a device driver properly, and you want to know how to find and import the correct drivers.
    Installing network drivers in the
    full OS
    Step 1 - Try network connection again
    It's possible that you might get a DHCP error from MDT, but when you try again later to connect the Deployment Share it works! This may be caused by a slow or malfunctioning DHCP server in your network. Re-check your DHCP servers, ensure that PortFast is enabled
    on your routers. If all else fails get your network administrators to document the DHCP delay. A long delay in modern networks is unnecessary. 
    Step 2 - Verify connectivity
    You may not have a driver problem but a network problem. Check the physical connection on the computer (Network installs on MDT *REQUIRE* a wired network connection, no Wi-Fi). Open a web browser. Check the IP Address (ipconfig.exe /all). Ping the Deployment
    Server, manually connect to the Deployment Share. IF you can't connect to the Deployment Share, neither can MDT.
    Step 3 - Find the Correct Driver Package
    Before you load the driver into MDT, first verify that you have the correct driver. There are scenarios where you may *think* you have the correct driver, but the driver will never run because the package is designed for a different OS/SKU/Platform/whatever.
    Install the driver package by:
      ○ Open the Device Manager (devmgmt.msc).
      ○ Find the network device in the list (ensure this is the wired device, not the wireless device)
      ○ Right click on "Properties" and click on the "Details" tab.
      ○ From the "Details" tab, select the property "Hardware Ids" select all the values, and copy to the clipboard, it would be a good idea to save for later. Should look something like:
          PCI\VEN_8086&DEV_1502&SUBSYS_21F317AA&REV_04
          PCI\VEN_8086&DEV_1502&SUBSYS_21F317AA
          PCI\VEN_8086&DEV_1502&CC_020000
          PCI\VEN_8086&DEV_1502&CC_0200
      ○ From the "Driver" tab, click on "Update Driver…", click on "Browse my computer for driver software" locate the driver package on the local machine or USB Drive, and install the package.
      ○ You should get a confirmation that the driver package was installed.
      ○ IF you do not get confirmation, MDT driver installation may not work.
     Windows will install the driver starting with the *.inf install package, and will typically include a *.sys (binary) and a *.cat (digital Signature). If the driver package has been re-packaged into a *.cab, *.zip, or other compressed *.exe file, the
    package must be extracted first. This is a hard requirement for any driver used by MDT and/or SCCM. All driver packages that are signed by Microsoft (WHQL) will be installed from the *.inf file, and you should only use devices that have the Microsoft WHQL
    Logo as a sign of quality.
     If you need a help on where to find driver packages for your devices, the 3 largest Computer OEM manufacturers supply drivers grouped by Make and Model that are easily imported into MDT and SCCM. See:
    http://deploymentbunny.com/2014/07/08/back-to-basicwhere-to-find-drivers-for-servers-and-clients/
    Step 4 - Load driver into MDT
    If you have more than 20 driver packages, or if you anticipate you will have more than 20 drivers, you should start grouping your drivers in sub-folders for organization. One popular method is to group by Computer Make and Model. Ensure that you are using the
    correct Driver Selection Profile in your task sequence. If you are unsure, disable any selection profile(s) to ensure the driver is installed correctly.
    Step 5 - Run the full MDT installation
    During installation MDT will perform the following:
      ○ Run the PNPEnum.exe utility and capture output to PnPEnum.xml. The VEN_Xxxx and DEV_Yyyy from the "HardwareIDs" property above must be present in this list. Otherwise we won't have a match.
      ○ Search through the %DeployRoot%\control\drivers.xml file looking for a match for the HardwareID. MDT may filter the search based on the folder search type.
      ○ MDT will copy each matching driver to the local c:\drivers directory using the xcopy.exe command. You can search (grep) for the string "xcopy" in the ZTIDrivers.log file, that will get you list of all driver packages matched by MDT.
      ○ MDT will allow the machine to boot into the NEW OS, and Driver Installation will begin in the OS. IF there are multiple drivers found and copied locally, the Windows (not MDT) will determine the best one. The c:\windows\inf\SetupAPI.*.log files
    will detail which drivers copied locally were installed (or *not* installed).
    Installing Network Drivers in
    WinPE
    Step 6 - Try the network connection again
    (See above
    Step 7 - Verify Connectivity from within WinPE
    Verifying network connectivity will be a bit more difficult in WinPE, since we have a limited User Interface, so all investigation must be done in the debugging mode (Press F8) cmd.exe
      ○ Try connecting to the Deployment Share:
      c:\> net use * \\MDT\DeploymentShare$ /u:UserDomain\UserName *
      ○ Try pinging the Deployment Server:
      c:\> Ping.exe MDT.Corp.contoso.com
      ○ Verify that you have an IP address ( ipconfig /all ) If you have an AutoConfiguration address - Driver OK - WinPE can't reach the DHCP server. If you have "Media Disconnected" - Driver OK - Physical adapter not plugged to network. If
    no devices are listed - Driver bad - Driver not installed.
      ○ Check the x:\windows\system32\WpeInit.log - This log will show the network driver (if found) being installed.
    Step 8 - Verify driver packages are getting included into WinPE
    Firstly, verify the correct driver package from within the full OS above. By default MDT will import *all* Storage and Networking drivers into your WinPE image. However it is possible to change the subset of files copied via "Selection Profile" or
    other method. Cross check your WinPE Driver Settings.
      ○ From within the MDT console, right click on the root of your Deployment Share and select properties.
      ○ Click on the "Windows PE" tab, and the "Drivers and Patches" sub tab for both x86 and x64.
      ○ Your Network Drivers package must be in the "Selection Profile" if enabled.
    Finally verify that the correct Network Driver package is being copied to WinPE. If necessary this may include setting up a debugger to watch the MDT Provider build the WinPE Image from scratch. My preference is to use the SysInternals 
    http://live.sysinternals.com/Dbgview.exe tool.
      ○ Open up the MDT console.
      ○ Download and run the DbgView.exe tool.
      ○ Update the deployment share in question.
      ○ The DbgView tool should show what drivers were copied to each WinPE Image.
    Other
    Whenever you add a driver into the MDT console, you must update the deployment share for that drivers to be added to your WinPE Image. If you are unsure, select "Completely regenerate the boot images." to ensure the drivers is imported. Additionally,
    you must copy the updated LitetouchPE_x??.wim and *.iso files to the other consumers of the WinPE image like WDS/PXE and or any USB offline media.
    Note that some Broadcom NetXtreme class of drivers have a multi-function driver architecture that may have difficulty loading in WinPE. Ensure that you load the "RIS" class of drivers from Broadcom in your MDT environment. 
    Note that by default MDT does *NOT* support the installation of Windows over Wireless network devices (Wi-Fi). The MDT installation sources must either be available through wired networking, or offline (USB Flash) media.
    This post does not discuss origination of drivers within MDT ( Chaos vs. Total Control ), that is a different topic.
    http://www.deploymentresearch.com/Research/tabid/62/EntryId/112/MDT-2013-Lite-Touch-Driver-Management.aspx
    Further Help
    If you are still having problems with drivers in via MDT, ask the experts in the MDT Technet Forum:
    Include a short description of the problem. Including the Make/Mode if necessary.
    Include the HardwareIDs from the Device Manager (Devmgmt.msc) into the post (from above).
    Copy your known good driver package (step 3 above) to OneDrive.
    Copy the following log files to a public site like OneDrive and include the link:
      ○ PnpEnum.xml (from Client)
      ○ Bdd.log (From Client) - or at least the ZTIDrivers.log file.
      ○ c:\windows\inf\SetupAPI.*.log (from client)
      ○ %DeployRoot%\control\Driver*.xml
      ○ %DeployRoot%\control\SelectionProfile*.xml
      ○ %DeployRoot%\control\settings.xml (if problems in WinPE)
      ○ x:\windows\System32\WpeInit.log (if problems in WinPE)
      ○ If the MDT server is not including your driver package in WinPE include the DBGView log.
    This post is by Keith Garner - Keith was a developer on the MDT team where he developed the ZTIDrivers.wsf script, he also worked for the Windows Hardware Quality Labs as a technical PM on Driver Quality, and developed samples for the
    Microsoft Device Driver Kit (DDK) specifically around the area of Device Driver installation in the OS (Windows NT 5.0, 2000 and Windows XP). (So yes, I know drivers :^).

    OK. I have redone the drivers for WinPE which has reduced the image size by about 200MB. Unfortunately the problem persists.
    Is there anyway to turn on some sort of boot logging so I can see what driver it is failing on?
    I am also still seeing the weird behavior of it working over PXE but blue screens when booting from USB. Can anyone explain that?

    Hello..i recently upgraded my G40 to win7 64bit and have been very dismayed at all the missing drivers.
    so far
    1 Cd/hd dvd drive - driver not supported on this product - it was when it was on vista 32 - now i just get cd drive error.??
    2 tv tuner - no driver available
    3 av controller - no driver available
    4 acoustic silencer - no driver available
    5 finger print software - installed driver - no hardware found?? it definatly has one ..im looking at it.
    6 hdmi control manager - no driver available
    7 infrared driver- no driver available
    some of these drivers i can do without - (finger print im not worried about 0 but the CD/HD DVD drive is a real problem..
    Im normally reasonably fine with installing all these drivers...but it seems there are non there ..or they dont see the hardware....please help.

    Wait a moment you are mixing something.
    Do not mix CD/DVD driver and HD DVD driver.
    When you install operating system optical disc drive must be recognized properly. If you have problem watching HD DVD movies that completely other issue.
    So, is optical disc drive recognized properly? Can you use music CDs and watch DVD movies?
    If you cannot find Toshiba HD DVD player for 64 bit OS try to use some other players. I don't have HD DVD media and cannot test it for you.
    PCI memory controller is maybe cardreader.

  • T500 Windows 7 Wifi Connectivity/Missing Drivers

    A few days ago, my T500 (Windows 7 Ultimate, 32-bit) crashed and went through a startup recovery process. When it was finally logged into Windows, I was unable to detect or connect to any wireless networks and Google Chrome (my primary browser) was gone.  After I couldn't find any restore points when running Windows Restore, I decided to just manually restore the missing components. I was able to connect to the internet via ethernet and reinstall Chrome (albeit missing all of my bookmarks and plugins), but still had issues with the wireless connection. Windows Network Diagnostics returned "There might be a problem with the driver for the Wireless Network Connection adapter," but was unable to troubleshoot the issue.
    Windows Device Mangager showed no missing network adapter drivers, but under "Other devices" each of the four items were missing drivers:
    Base System Device (x2)
    PCI Serial Port
    PCI Simple Communications Controller
    I've downloaded a number of drivers, (including several variants of Inter AMT and the Multi Card Reader, as suggested by similar threads), but none have addressed the four missing drivers. All attempts to update the drivers were unsuccessful.
    Could the missing "Other devices" drivers be causing my wifi issues? 
    Are there drivers I can update them with? 
    Is an updated driver available for the wireless network adapter (currently 12.4.1.4; none of the downloads have updated it)? 
    Is it possible to recover my data from the old installation of Chrome without any backups or restore points? (obviously I should have been backing up my data)
    Thanks.
    Lenovo T500, Windows 7 Ultimate (32-bit; upgraded from Vista Ultimate 32-bit), T9600(2.8GHz), 4GB RAM, 256MB ATI Radeon HD3650, Intel 802.11agn wireless (Intel Wifi Link 5100)

    I ran sfc /verifyonly and sfc /scannow; it said there some corrupt files and to check CBS.log. The file was fairly long, and I couldn't really discern any relevant information from it. Ctrl-F didn't find anything related to the driver. I don't know what, if anything, was fixed, but the driver issues still remain.
    I've tried to manually delete the old 12.4.1.4 drivers with no sucess. Even as an administrator in safe mode, I still couldn't modify anything. SYSTEM and TrustedInstaller are listed as having full control over the files, and there was no option to change the permission settings (check boxes were grayed out). 
    Is there anyway to modify those permissions so I can delete the old drivers? Would it helpt to reinstall 12.4.1.4? I've looked for a download online but haven't found anything yet. The only other solution I can think of is reinstalling Windows 7. Does that sound like the right course of action? The wireless card and the other drivers haven't had any issues up until now. It seems like some system files were corrupted when it went through the startup repair that started all of this.
    Thanks
