Vaio E series touchpad Problem
Sorry for the late response Jimmy.
What Operating System are you using? If you haven't changed your OS then you are using Windows 7 since it is the default OS for the whole series. Touchpad problems with E series are quite common. Just go to your Control Panel, type "Mouse" on search and then select "Change Mouse settings". On the "Pointer Options", Check the "Enhance Pointer Precision".
If this does not work, bring your laptop to a Sony Service Center. I have a friend with a problem like your. She also has a Vaio, different series though. Her problem was caused by the hardware itself. I hope your laptop has warranty.
It seems that the signals which are produced by the touchpad are not identified or not clear to recognize to your laptop. First you have to update your drivers or reinstall your system.
If those options didn’t work then there must be an error in the circuit of the touchpad. Repair it before the situation get worst.
