Touchpad not working

[eem2am]

Hi,
My Touchpad on Lenovo Yoga 510 stopped working today (it was ok yesterday).
(My USB mouse works though).
"Touchpad" is a word i cannot see in the device manager.
Do you know how to get the touchpad back?
I use Windows 10.
As attached shows, there is no option to turn the touchpad on or off

Look along the Function keys for one that enables/disables the touchpad (such as F6, F8 or Fn+F6/F8/Delete) If the shortcut key does not disable or enable the touchpad, go to Lenovo support website to download and install the latest touchpad driver, then retry.
