The Lenovo Community Knowledge Base is integrated with the discussion forums and allows members to find valuable articles through search, or by browsing the knowledge base directly related to a particular set of products and using date range and categorization labels to narrow the range of results.


The Community provides easy navigation from the discussion forum areas to the related Knowledge Base functions.  Simply click the small book icon to the right of a discussion board to access the related KB.




If a discussion board does not have the book icon to the right of it, this means that the knowledge base for that forum has not been activated.  These will be systematically rolled out over the course of several weeks begining in mid-May 2010, and we expect to have most KBs activated with some starting articles in place by June, 2010.  The value of this resource will grow over time as more community members begin to contribute and harvest the collective knowledge of thousands of existing solutions .


Available articles in the specific KB are displayed 1 to X and may be browsed by pages.  The filter functions in the left navigation may be used to refine displayed articles by date range and labeled content.   Depending upon member permission levels, additional filter options may be provided for article and publication status. The search function at the top of the page can be used in normal search or advanced mode and will search the knowledge base and forum discussion areas based on the terms entered.


Depending on member rank and permissions granted, the Knowledge Base Dashboard provides additional options to help manage articles.    Nominated discussions and solutions may be provisionally accepted or rejected, and articles started from scratch or based upon previously nominated discussions and solutions. 





Community members can collaborate to build more complex articles, drawing in content from the original forum discussions they were based upon, supplemented with additional content.  The Community Knowledge Base keeps track of content authorship, and credits the original material's author as a contributor whether or not he or she is the member editing / building the KB article.  


Drafts may be saved and revision histories are maintained and may be compared while editing to allow collaborating members to keep up with changes being made by other members.  When an article is ready , it can be submitted for publication.


Once published, the community can comment on articles, and this feedback can be a valuable way to collect additional information to be included in a future edit.  More advanced members may edit and republish unrestricted articles.

Dear all I am using a lenovo 3000 N100 machine, Model 0689, with 32 bits running XP . I upgrades 3 days ago to Windows 8.1. The update went well but for one thing -  I do no have any sound now.  The machine has a Digital Audo (S/PDIF) High definition device.


I have tried several things without success. I am hopeful that someone in the community has a solution.


Secondly I backed up all my files prior to the upgrade using the backup facility on XP. How do I restore these files ? Win 8.1 does not seems to have the same backup program that XP had.


I am getting extremely worried now.


My new Lenovo B590 laptop has a magnifier which increases and decreases the size of the screen with no input from me.  There's no pattern.  I have to constantly reset it to default.  I have unchecked the "start magnifier" option in the display options to no avail.  The thing has a mind of its own!  If I can't correct it, can I disable the function permanently?  I don't need it.  Don't want it!  Thank you!  (Screen size changed twice while I typed this!)

hello , I have problem in rebooting the system using bootable error occurs with the message "INVALID PRODUCT KEY" though i am not getting any option to enter KEY..System directly give me this message....What should i do???????????????


G470 cannot upgrade to IE11 or IE10 due to Win7 BSOD.

G470 notebook, Windows 7, BSOD Iqdpmd64.sys " Page fault in non paged area" running Internet Explorer 11 ( you can re-create this BSOD with playing multiple Youtube video tabs at the same time). 

The BSOD seems to occurring to labtops with Internal VGA graphics and AMD( ATI ) graphics together. My desktop and old Thinkpad X61 have no problem with IE11 + Win7.

HP forum tells to remove KB2670838 to fix the same symptom. But if you do, IE 11 is either removed together during the process and returns to IE8 or IE9 - if you have KB2834140  installed. MS is withdrawing support for old IEs and forces to go with IE11 but G470 with Win7 cannot go. I have tried latest VGA drivers without problem fix. 

So who should fix the problem?  MS or Lenovo?


Look at Google search: There's no fix for most Lenovo Laptops other than uninstall the "evil update KB2670838 " at this time... So have to stay with IE9,,,


hi admins


please help with my Lenovo g475, after i cleanboot, its always beeping and blackscreen everytime i rebooting


I bought the Flex 2 14 last month but cannot install my prized software, SAS Ver 9.2.  I am getting the following error message : This application does not support your platform.


The instruction from SAS is to remove the Windows Update KB2919355, but I cannot remove the file. Whenever I right click on the file the uninstall option does not come up.


My co-worker with another brand machine had the same problem, but when the solution from SAS is applied it works on his machine. Software install and works quite well.


Solution from SAS is to remove the update KB2919355. Instruction to remove update: Go to Control Panel, System Security, Windows Update. Check KB2919355, Right Click and Uninstall.


I really need a solution to this problem, because I am not able to work on the go just now. I really need help badly in this regard.

Please suggest me.



There were a LOT of issues with looong boot times after BIOS update. This solves the issue (worked 100% on my T500). This problem is NOT software related. User must wait for boot screen and enter BIOS to edit two fields.


If these long boot symptoms, following the BIOS update occur, multiple customers have reported success in resolving them  by disabling Intel AMT and setting the security chip, TPM, as active in the BIOS.


Steps to disable Intel AMT and enable TPM settings as below.


  1. Boot into BIOS
  2. Select Config
  3. Select Intel AMT
  4. Press Enter key on Intel AMT Control and select Disable
  5. Press ESC twice
  6. Select Security
  7. Select Security chip and select Enable
  8. Press F10 and click Yes.

My Lenovo laptop G580 displays error code Oxc0000185 then switches itself off, what can I do to stop this, it will not stay on long enough for me to activate any repair programme?


I have a w540 Thinkpad with Windows 7 64-bit.  My Microsoft Vitual Wifi miniport adapter and Microsoft Vitual Wifi miniport adapter #2 keep getting turned off.  I would like to know why, and what I need to do to stop it. 


On my W540 Thinkpad with Windows 7 64-bit, I keep getting messages from my Device Manager that the Microsoft Virtual Wifi Miniport Adapter and the  Microsoft Virtual Wifi Miniport Adapter #2 have stopped working.  In order to find out anything about it, I have to switch to the Administrative account.  When I do so, and look at the Device Manager, both devices report that "Windows has stopped the device because it reported problems (Code 43)"


What does this mean, and how do I fix it?

I am not sure where to post my issue with my Sisley S90. But I hope you can direct me to the right path or help me with this concern.


I bought my Lenovo Sisley S90 about 3 weeks ago. I am currently having issues with my Google Play Music. Whenever I download music from an app or ask someone to bluetooth a music, it is automatically being deleted on my Google Play Music list. I tried uninstalling the downloader that i'm using, try to delete cache of the Google play but it's still happening. Is there a setting that I need to adjust on my phone, or is it a common issue? My friend also have the same phone but she is not experiencing any of these.

Thank you for your assistance!

Subject: New Lenovo P51 cannot support 4 displays (Notebook plus 3 external displays).


Message body:

Almost a week ago I received my new P51 loaded with all available components, as did my last Lenovo W530. The P51 appears to be a great machine.  My current problem is that I cannot display 4 screens (notebook plus 3 external displays). Since I have used my W530 with 4 displays for over two years I fully expected to achieve the same with an even more powerful Notebook.


The new P51 has two 512 GB SSD drives, the Intel Xeon E3-1505M v6 vPro MB CPU, a NVIDIA Quadro M2200M 4GB graphics card, 32GB(16+16) DDR4 2400 SoDIMM, a notebook display of P51 FHD NT 2D MC CS WLWW and the latest Windows 10, 64 bit operating system.


Since I received the P51 and its docking station (P/N: 40A50230US) I have connected the three external monitors to the docking station via a HDMI port, a DVI converter to HDMI and a Display Adapter converter to HDMI. The BIOS was updated to the latest and the 256 Mb default memory for the displays was increased to the 512 MG setting. I have also moved the displays and cables around to confirm that cables are fine and only two external displays will be seen at any time.


In speaking with Lenovo hardware support, one individual said I needed to subscribe to software support to get the BIOS changed. Later, a second person said that I needed to play around with the BIOS settings and it should work. I have also rebooted the system a few times. Unfortunately I still cannot view 4 displays. 


As an IT, Telecom and Cybersecurity SME and Project Manager I realize that since my system is a newly released product (April 29, 2017) problems are expected. I am reaching out to the Lenovo community hoping that some of you have also upgraded to the latest, greatest and most powerful Think Pad. Perhaps some of you may have experienced the same problem. I doubt that the new P51 would support less displays than my 5 year old W530.


Any help or advice from the community would be greatly appreciated.
