I mostly use a mouse and I am getting annoying mouse pointer jumps when I inadvertantly touch the touchpad while typing. It seems like just pressure on the area outside of the touchpad is enough to make the pointer jump. I would like the touchpad to be disabled when a mouse is present on the system and be enabed when no mouse is present. I would not want to be caught having to find my way to the Control Panel using keystrokes.
It does not seem like this is possible so I am hoping that Lenovo is monitoring these posts.

Hello. What type of ThinkPad do you have and which OS are you running?

The option to automatically disable the TrackPad is not available through the UltraNav utility, but there you can just turn it off if you don't want it active while using the external mouse. Another option is to open the Charms - Settings - Change PC Settings - PC and Devices - Mouse and Touchpad and change the delay for the Trackpad to Medium or Long delay, which will ignore these accidental touches.
If you are comfortable in editing the registry, there should be an option there (present in my T430), through the Synaptics driver to actually enable the feature you're asking about, i.e. to automatically disable the TrackPad when connecting an external mouse.
Open up regedit - navigate to HKEY_CURRENT_USER\Software\Synaptics\SynTP - double click DisableTouchPadIfMousePresent and change the value to 1 and reboot the machine.
See if this doesn't do the trick.

Thanks but I do no want to disable it completely. Then I would not be able to enable it if I did not have my mouse.
What I have done is put it into Classic Track Point Mode Only. So now you really have to press hard to get a click. And I still have the track point to use to enable the track pad if I do not have my mouse.

You'd always have the TrackPoint enabled unless you specifically disable it in BIOS or through the UltraNav utility. The registry change only applies to the TrackPad.

Yes, I want this feature too. This is only the second laptop I've ever owned that didn't have this feature standard (the first was a Surface pro 2, and my first laptop was 1997). It's truly disappointing that Lenovo doesn't provide this basic and crucial capability. One wants to use the trackpad when the mouse isn't hand, but wants it disabled when a mouse is being used. I think almost all people wan this behavior, and this "premium" Thinkpad can't do that. There must be a fix somehow.
