Laptop charger has 2 plug pins only

Dear All,

I have purchased Inspiron N5010 from Seoul (South Korea) before 8-9 months. Initially for 3 months, I had used laptop in seoul very well.

After that I am using laptop in India. But here i have faced lot of problems like Motherboard replacement, Bluetooth card replacement & touchpad and Keyboard replacement. 

In Seoul all Electrical connections with 2 pins only. Hence I got dell charger with 2 pins.

Dell engineer said I am facing all this issue because of 2 pin charger only. Because in India we used 3 pin charger with Earthing connection.

He recommended me to use 3 pin charger to avoid all this issues.

My question is really I need to convert 2 pin charger to 3 pin?? And if so, can i get seperately  charger connector cable ( from adaptor to plug socket) in market as charger is working well. But I want 3 pin connector cable..

Regards,

Nilesh
