Re: erratic touchpad when AC charger is plugged

Same issue here!  New laptop and new AC adapter.  What's weird with mine is that my touchpad is only erratic when my AC adapter is plugged in on one side of my house.  If I take the laptop and the same adapter and plug it into an outlet on the other side of my house, then it works fine.  Until I did a Google search and seen that there a lot of people experiencing this problem, I thought maybe my house power might be hosed up.

 Like everyone else though, when it's not working, it works fine all the time on the battery.

Let me know if Dell ever decides to find the real root cause to the problem and fix it!
