In the first week with my Y700, sometimes, when the pc started, the touch screen just didn`t work and i had to reboot in order to use this functionality. Now, there`s nothing i can do to use the touch, it`s like the computer never had a touchscreen.
Looking in device manager i haven`t found anything related to the touch interface but there is a " Unknow USB Device" in Universal Serial Bus controllers tab.
What shall i do?
Solved! Go to Solution.

You should contact Support and ask for a warranty repair. Go Here - http://support.lenovo.com/us/en
Search for your product, enter the serial number (details) and create a warranty repair case.
You can contact lenovo by phone as well -
If you purchased this within last 30 days, you can also return the product to Lenovo. Thanks.
