I use Lenovo S510p Ideapad that I've had for around four months.
I recently today, I installed some Windows updates. (I didn't upgrade to Windows 8.1 though.)
When I rebooted my touch screen had stopped working and I can not find out how to get it to work again. My drivers are all up-to-date and I have not done anything to damage the touch screen function.
What can I do about this?
