Touch Screen malfunctioning of my Sony VAIO
My Sony VAIO T series 15, a touch Ultra-book, but for the last few days its touch has become very irresponsive. Some parts of the screen are like they are just not receiving what I touch i.e it gives no response, while others are too slow, if I touch to close an app it will take 10 seconds or more to respond, is it something with hardware or internal problem? What should I do?
