My Windows 8 touchscreen quit working. I found quite a few posts with the same issue. The computer I have is a Sony Vaio T Series Ultrabook. The model number that I have is: SVT1511L
The solution for me was to download and install the Firmware update. I don't know why it wasn't automatic. I found the update at: http://esupport.sony.com/US/p/swu-download.pl?mdl=SVT15112CXS&upd_id=8475&os_group_id=24
Let me know if this solution works for you.
