W540 touchpad - erratic behavior in Windows 8.1

This is not a rant about the touchpad design - I'm actually not too bothered by it.

 

I'm having major issues using the touchpad even with the latest W540 drivers on Win 8.1. I have v18.0.7.57 which is the latest available as per Lenovo's downloads site. The cursor movement locks up for several seconds, then starts highlighting text I haven't selected, scrolls when I'm not using 2 fingers etc. Overall, it's very annoying. I have disable 'tap to click' and this helps a bit, but I still have the locking issues. Also, 'Synaptics touchpad 64 bit enhancements' is one of the top CPU consumers on the system, especially during the lockups - I can't imagine why an app that handles input should be consuming so much CPU!

 

I have uninstalled, reinstalled (rinse, repeat) several times and haven't found any improvement.

Hi W540_tp,

 

Welcome to Lenovo Community!

 

As per the query we understood that you are facing the issue with Touchpad on your ThinkPad W540.

Uninstall the current driver and check with Microsoft generic driver.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: W540 touchpad - erratic behavior in Windows 8.1

Hello,

 

The generic microsoft driver does not support two fingered scrolling and the gestures. Is there a version of the Synaptics driver that doesn't have this issue? Is there a fix in the works?

 

Are there other users with this issue?
