Here I'll go into more specifics of what I have tried. I wrote a blog post about this modification when I did it and there is a bunch of comments mentioning different drivers so it may be worth digging though them and seeing what you can get working:

You may find that the installers will refuse to run due to the machine model not matching but you should be able to force it to install by doing "Update Drivers" in Device Manager.

Mine is a Synaptics unit, hence using the Synaptics drivers however people with the ALPS version suggest that this driver works: It's also worth noting that there are two different manufacturers of those Touchpads - ALPS and Synaptics. That said, I run Linux on my T440s so I've only very briefly tried the touchpad with Windows (8.1 Pro) so things may have changed. I actually did this modification to my T440s a while back and had to use the n10gx25w to get it to work properly under Windows.exe].exe. Since this is the touchpad from a newer model and not a W540 you should try installing the drivers for a machine that shipped with that touchpad such as the W541, W550s, T450s.etc. I am a technically competent user and can not figure this out. So its not a Windows issue and is definetly some sort of issue with the touchpad.Īnyone know what is causing this massive headache? I just want gestures and 2 finger scrolling and such. Iv'e also tried putting this touchpad on a Windows 7 W540, and it doesnt work their either. Still no way to customise my new touchpad. Still no thinkpad tab in the mouse settings.

After hours of work and countless restarts I decided to do a new fresh install of Windows 10 and install the drivers. I tried near everything in the book to fix it. I then uninstalled the ultranav drivers and reinstalled the newest ones, they installed without error. I then tried to go into the mouse settings in control panel to adjust things, and there was no thinkpad tab for changing advanced mouse settings. So i succesfully installed the new touchpad on my W540 within 5 minutes, and everything was working fine it seemed. The new ones are much better, so I proceded to do that. I saw that it was possible to install a new touchpad from the W541 onto the W540. I own a Lenovo W540 with Windows 10 on it and the default touchpad is absolutley terrible.
