How to resolve the problem "touchpad is not working properly while charging"

I had same issue when i was using Dell INSPIRON N4050.

I was worried about this irritating nature of touch pad...and i  searched so many forums but there was nothing special and exact solution for my problem.

but my search for the solution was in vain.

i have found a good solution for this problem.

Please remove any other chargers of phones or tablets like Samsung, blackberry, or iPhone,  which is connected in the same wall socket using adapters or another socket  in the same room.

it will be working..if still out of order  call an electrician and check your Earth line in the main power supply line.

one thing more don't plug in Power socket which provide electricity by UPS.
