Is your touchpad jumpy and erratic

well think about what changes did you do to software, if you didnt do any change, and no new softwares were installed, you can most certainly put your head on hardware. I have a lenovo y410 and my touchpad was jumpy and it used to get stuck every 5 seconds. Finally i realized it was due to the power supply i purchased newly from ebay. The supply was good, it was shorter than the OEM though, but the difference is the fact that it had only 2 pins. Seems static is building up and disturbing the electro-static touchpad that my lenovo has (most laptops have that). So the solution was to get the three pin AC power supply. See how power supply can affect the functioning of a laptop !!! interesting isnt it. Ebay has a small section for feedback, i wish i could have given more feedback there , not necessarily that the product is bad, but it is not suitable for me for sure.
