I have HP Pavilion dv4-1428 and under that I have installed the windows 7. But I think the touchpad scroll not reactive. Sometimes moving, sometimes does not scroll. Sometimes I have to do it several times before you travel. I used notepad but not all had this problem in two-finger scrolling. I thought maybe it was a driver problem to visit the website on, but we recommend going to the manufacturer's website for most of the drivers applicable. Now I don’t how to solve this issue. Can anyone suggest on this issue
