S340-15IWL Mouse destroys touchpad

2019-09-30, 9:49 AM

Hi all,

after unboxing the touchpad on the S340-15IWL worked like charm. Unless a bluetooth mouse came in.

 

Actually, the HID-compatible mouse driver by Msft seems to have eliminated the touchpad completely from the system. There's no more touchpad in the Device Manager at all. The installattion of the Lenovo official driver does not help: there is no pointing device other than the HID mouse any more on my Ideapad. F6 clearly has no effect either. When I remove the mouse and restart, there's no cursor.

 

Should I uninstall the mouse driver to make it run? What will happen when I connect a mouse again to a USB port? All the same? Could the touchpad be used instead of the mouse and vise versa via some simple switching process? Like "disconnect your mouse - touchpad starts automatically"?  Or should I perform a driver magic every time? 

 

Thank you.

Solved! See the solution

Solved.

 

First, uninstall the mouse driver. I also uninstalled the ghost "second keyboard" featuring the yellow trinagle as it  " can not be started".

 

Second, install the genuine Lenovo touchpad driver set (for both pad producers; only the right one will install duly - but silently). In the case of S340, the set should be found via Google, as touchpad is not present on the appropriate Lenovo driver page for some reason.

 

Third, reboot. You should finally see two mice in the Device Manager, of which one is the touchpad.

 

Now the touchpad and whatever mouse attached work together smoothly. If you choose so, press F6 to turn off the touchpad. Press again to re-make it work.
