Dell Inspiron 15 3542 windows 8.1 touch and pen issues

I have a Dell Inspiron 15 3542 windows 8.1 that had touch and pen when I first received it ( around 4 months ago ).

After windows updates and Dell bios Version A04 update my touch and pen no longer work.

In fact if I go to windows and look Touch and Pen I see (no pen or touch input is available for this display)

Also I have refreshed the laptop and reinstalled windows and it still doesn't help.

Anyone have this similar issue and has a fix ? any help would be appreciated

thanks
