“How to fix the vertical scroll of the touch pad? I just bought this Sony SVE1511RFXB laptop. I have tried so many times to increase the speed of the vertical scroll of its touch pad, I did it through control panel and vaio control center too by increasing the speed of the wheel. it does take effect but after sometimes it goes back to the default speed which is very slow. it definitely goes back to original speed when I restart it. Could you please help me out. Thank you!”
