Touchpad not working on W540

2020-09-13, 19:37 PM

I am having a very frustrating time with the touchpad on a W540, to the point that whatever I try the touchpad and trackpoint will not work.  Hoping for some ideas to get it working again. |Some details 

  • It is not a HW problem, I have booted with a Linux distro and it works well
  • Running Windows 10 with all updates
  • The touch pad was working albeit I had to re-install drivers occasionally
  • The driver that was working :- 19.0.17.135
  • Since it failed have tried a number of drivers including the latest from the support site (19.0.17.142) Oddly it shows on the W540 download page but W540 is not listed as a support  device
  • One of the main symptoms is, on the mouse control panel properties page - Thinkpad tab - the pointing options field shows an empty list. (it use to show options of touchpad & trackpoint,  just touchpad and  just trackpoint)

 

Any suggestions to resolve this are much appreciated 

Dave
