Dell Inspiron N5110 15 R Touchpad Problem

Hi all,

I bought a dell inspiron N5110  15 R laptop a month back (28 October 2011))with the following configuration,

i5 Procsser

4 GB RAM

500 GB HDD

Window 7 

Sometimes when i connect it to AC supply my touchpad becomes sluggish and its not responding properly.

but when i remove the Charger or data card it works properly .

 But sometimes even when AC is plugged in the touchpad is working perfectly.

This makes me wonder whether its a adapter problem or touchpad problem.

Plzzz let me know the exact solution ...:emotion-6:

 Regards

Kunal
