P52 - Trackpad middle click not working anymore

#1 Post by H-Atkinson » Mon Nov 21, 2022 1:21 am

For whatever reason a Windows update has broken the middle click button on my trackpad. I know it still works in hardware and that the issue isn't the trackpad firmware since it still works in the BIOS self test, but for whatever reason something happened to break the driver (presumably) with Win10 22H2. I've tried everything I can think of (trackpad firmware reflash, clean driver reinstall, using generic Windows drivers, forcing it to use a whole bunch of versions of Lenovo's driver), and nothing has worked. A factory 1809 install works fine, a clean 22H2 install does not, even with drivers. Ideas? I don't have my P53 on-hand to test if it has the same issue, am dailying the P52 while Lenovo replaces the faulty motherboard in my P1 Gen 5, and this is a seriously hinderance to my work, and I've run out of ideas.

I've found one dead-end reddit thread (https://www.reddit.com/r/thinkpad/comme ... correctly/) that described the same issue a year ago, but I have no idea if its actually the same problem, or if they ever fixed it.

Can't help you here with W10, but that Reddit link shows the problem already existed with W10 21H1.
They also mentioned an Elan touchpad, which sounds iffy to me.
Sure enough, further searching finds this: https://www.reddit.com/r/thinkpad/comme ... t14s_with/
HTH.

I should clarify, its not the middle trackpoint button, that works fine, its the dedicated middle click for the touchpad.

As for the issue existing in 21H1, I'd believe it, I went straight from a clean factory 1809 to 22H2.

Dare I say it: why not use a mouse?
Nowadays I use a small Logitech M330 Silent mouse with my T440p.
Its clunkpad was upgraded with Alps touchpad+buttons, but the touchpad has been disabled.
I use the trackpoint maybe once or twice a month.

I have a mouse, and I mainly use the trackpoint in daily use, but navigating CAD with 1 hand while holding the laptop in the other is best done with a trackpad. Middle button not optional.

Considering it, but again, the issue isn't hardware. The buttons work in the BIOS self test and in a clean Win10 1809 install.
