T450s scrolling issues

Question

Hi there! I recently received a new T450s and after performing a clean install of Windows 7 and updating my computer, I find that scrolling with the trackpoint (using the middle button we all missed) is broken. In every application, scrolling is either insensitive, barely works, or most often randomly jumps a page while scrolling, as if someone was pressing PgDn every few seconds. I started with version 18.1.27.20 of the UltraNav driver, but it was simply unusable. Downgrading to version 18.1.27.14 helped things somewhat, though I am still nowhere near an acceptable point. Adjusting settings has had no impact. Two finger scrolling on the trackpad works beautifully in every application. Suggestions? Comments?

Answer 1

I am investigating these customer reports of dissatisfaction with the response on T450s TrackPoints and TrackPads.
I'd like to get some more information:
Are you running Win 7 or Win 8.1?
Has your laptop been updated to Synpatics driver 18.1.27.20 release 4/3/15?  http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t450s/downloads/DS102029
I reviewed and sorted your feedback:
TrackPoint:
In-line flash images conflict with the T450S trackpoint scrolling
The trackpoint scrolling sticks and intermittently jumps during use
In-line flash images conflict with the T450S trackpoint scrolling
TrackPad:
Scrolling with the trackpoint using the middle button is broken
Scrolling with the middle button is lagging and slow
In every application, scrolling is either insensitive, barely works, or most often randomly jumps a page while scrolling, as if someone was pressing PgDn every few seconds
The scrolling function sticks and jumps while using a file explorer window
The trackpad also misses on 2 finger scrolling about half of the time
If you have any additional feedback for the TrackPoint or TrackPad, please add it so I can include it in my investigation.
Thank you,
