C340 touchpad not working

2020-01-19, 18:40 PM

Hi

 

My c340 touch pad stopped working yesterday.

 

Button press works but no cursor. Yes I have ensured the fn key and touchpad active. 

 

Checked driver HID is ok and current drivers. uodated to he latest bios Dec19 still nothing 

 

Deleted driver and reboot and reinstall no good

 

New windowsninstall still no good and now fn key does not switch on ir off does nothing.

 

Looks like a service call

Hi jaz41,

 

Thanks for reaching out.

 

Kindly provide the MTM of your machine, so I can check if there are any dedicated drivers for this machine.

 

Thanks,

Jack_Lenovo1
