Re: Re:Stuck with driver installation on Win10

Yes, I checked the hardware IDs and they are different (LEN0036). I put them into the GP which should prevent from updating, but doesn't.

 

 

Thanks for your assistance!

Re: Re:Stuck with driver installation on Win10

Hi,

I've just installed the creator update for windows 10 today and all 3 physical buttons stopped working. I though this should not happen since i have set the group policy to not update the synaptic driver. Has anyone experienced the same thing?

Yes the same thing happened to me.

After the creator update i had to deactivate the group policy (so i could install the correct driver) and go through the entire process again..

First n10gx25w, then n15gw07w, since i think n15gw07w alone wouldn't have correctly recognised my trackpoint buttons.

(although that's just from my previous experience, i didn't try directly installing n15gw07w this time)

Re: Is it possible to replace the button-less touchpad of a T440s with the 3-button touchpad of a T4

2017-05-29, 7:47 AM

Oh what a mess!

My admin colleagues did a fresh install of Win 10 on my TP 440s and the touchpad worked, but not the hardware keys.

A gfew days later I installed the Creators Update (accidently clicked OK ...). After that the device was disabled and was hidden in the Device Manager.

Then I tried to go through the steps above to get driver ..85 running. But I forgot to switch off the internet connection, so always driver version ..115 was installed by Windows. I established the group policy to prevent Windows from updating my hardware IDs, but Windows did not follow that policiy like it was a few weeks before (see above). I always got driver ..115.

Today I tried again but was not allowed to update the driver because of the policy (hmmm!!). Even after this policy was disabled or not configured the driver installation ended with an error related to the policy. I had to create a new policy that explicitely allowed the driver installation for that hardware IDs. Then I installed driver ..57 - rebooted - installed ..85 - disabled internet and removed the new allow policy - rebooted and all worked fine including hardware keys.

A few seconds after internet was enabled again Windows installed driver ..115 again!!

I have no idea how to fix this deadlock situation:

  • With the prevent policy activated I am not allowed to install drivers, but Windows does.
  • With the prevent policy removed I am still not allowed to install the drivers.
  • Whith a special allow policy enabled I can install the desired drivers.
  • Whith the allow policy removed Windows again installs driver ..115.

Windows feels very opaque for me.

 

Regards Christoph

(still missing the Trackpad keys...)

It is incredible than Lenovo is too stupid to release a driver that recognizes the right touchpad. What a joke this company has become!

Re: Is it possible to replace the button-less touchpad of a T440s with the 3-button touchpad of a T4

2018-01-04, 23:09 PM

I completed the install of a T450 type 3 button touchpad a few years (2015) ago on my T440s but it stopped working after I upgraded to windows 10 PRO 64bit from windows 7 64bit.  I was able to get it working today with a newer driver so figured I'd share my experience after reading through this thread.

 

My hardware ID for the new 3 button touchpad shows as LEN0036 in windows. Noted here as it was mentioned throughout this thread.

I ordered the 3 button touchpad from ebay a few years ago.  Looks to still be listed as ebay itemID 252005477202 if you search for that number on ebay. 

 

STEPS:

1. Download the driver from Lenovo https://support.lenovo.com/jp/en/downloads/ds104007 or search for document ID DS104007 on the Lenovo site.

 

 

2. Run the jbg214ww.exe and extract the contents to a folder and note the location. Example C:\DRIVERS\UltraNav_ds104007.  Do not run the installer after extracting files (uncheck "Launch Synaptics UltraNav Driver") on last screen and click Finish.

 

3.  Open Device manager and uninstall (remove and delete) the existing drivers under "Mice and other pointing devices".  Then restart windows.

 

 

4. After restart, the touchpad driver should show as a generic PS/2 Compatable mouse in Device Manager. The touchpad functions but with limited functionality.

 

5.  In Device Manager, update the generic PS/2 Compatable mouse driver by getting properties on it and selecting the update driver button.  Then browse to the path of the new driver noted in step 2.  Be sure the "include subfolders" box is checked when the folder path is specified.

 

6. The driver should be successfully updated to Synaptics Pointing Device and shown as follows with driver version 19.3.4.119.

 

7.  Restart windows and the driver should work as expected.  The "Mouse & touchpad" settings in windows settings should have the configuration for the Thinkpad 3 button touchpad now under "Additional mouse options".

 

--

This seemed to work for me.  I have all 3 buttons working along with the two finger zoom, side and bottom touchpad scrolling if enabled in the "Additional mouse options" settings, etc.

 

Good luck!

Re: Is it possible to replace the button-less touchpad of a T440s with the 3-button touchpad of a T4

The new driver JD2000 linked to worked for me.

 

I had previously done the replacement and installed the the n15gw07w.exe version of the driver following Erratic_Banana's procedure. After the most recent Windows update in Jan 2018 the driver stopped working -- the trackpad was detected as a PS/2 device missing a driver (similar to step 4 of JD2000's post -- but my trackpad wasn't working at all). Anyway, after using the driver in jbg214ww.exe everything is working again. Hopefully it stays that way!
