Hi All,

My touchpad no longer works.  It is no longer in the device list via control panel.  I used to run with the touchpad disabled if I had a mouse attached but this option has disappeared as I have no touchpad properties.  Obviously fn+F7 has no effect.

 

Any help most gratefully receieved.

JUST NOTICED

Pursuing another similar discussion I saw a reference to HID Driver I2C being a cause of the problem.  This is list as a problem by Device Manager on my machine. The driver is the latest version but the following is listed

This device cannot start. (Code 10)

A request for the HID descriptor failed.

 

Can anyone interpret this for me?

Hi,

I solved the issue by uninstalling the offending I2C HID device and rebooting.  Windows reinstalled the device and the touchpad worked immediately.
