Thinkpad T440P no option to disable touchpad when external mouse is connected

New ThinkPad T440p and the first issue I encountered is there is no option to disable the touchpad when an external mouse is detected. I don't want to do it via the bios or some other hack as I use the touchpad when it is not convenient to use an external mouse. So it should be able to do the switching as needed, this is a simple feature that other manufacturers have had for years and years. 

 

I already upgrade the UltraNav Driver to the latest v18.0.7.57 and that didn’t present a solution. I am running Windows 7 SP1 - 64bit.

It's technically part of the driver, so try the registry edit here if you can't find the option in UltraNav settings:

Re: Thinkpad T440P no option to disable touchpad when external mouse is connected

ColonelOneill,

 

The guide put me in the right direction but I had to adjust the value in the HKEY_CURRENT_USER versus HKEY_LOCAL_MACHINE

Registry Change

HKEY_CURRENT_USER\Software\Synaptics\SynTPEnh\DisableIntPDFeature

Dword from hexadecimal 22 to 33.

 

It is a bit frustrating being a long time Dell Laptop user that other manufacturers are not as diligent in making sure this feature is externalized in the control panel for users that have no registry access. Like is often the case in a corporate issued computer. 

 

So issue solved but again it would be great if this was in the Touchpad software versus having to change registry values. 

 

Thanks!

Re: Thinkpad T440P no option to disable touchpad when external mouse is connected

This registry fix only sort of worked it allowed for the touchpad to be disabled when I connect an extrenal mouse but it doesn't recognize the removal of the mouse. If I reboot the machine it starts up and works then pops up and says touchpad is dasabled due to external mouse yet there is not one connected. 

 

Any one seen this behavior or have a fix for this?

I'm having the same problem.

But going thru control setting every time ist still very cumbersome. Laptops form other vendors and even other Lenovo

Models have a special FN key for enabling/disabling the touchpad. Would it be able to change the behavior of one of the function keys to perfom this?

Re: Thinkpad T440P no option to disable touchpad when external mouse is connected

My model is a T440s; hopefully this helps on your model too. Also I haven't read the whole thread, I'm just assuming you're doing it for the same reason I am: My palms keep moving the mouse pointer. 

 

In Windows 10, open start and search "trackpad". You'll see "Mouse Properties (Touchpad Clickpad...)". Choose this one and NOT the normal "Mouse Properties" result.

 

In that window there should be a tab for ThinkPad, go to it, and under Pointing Options select "Use Track Point Only". 

 

This will make it so it only responds to the little red "nub" between your G, H, and B keys, and not the touchpad. 

 

Hope this works for you!
