Charger wire is getting hot and melting !! Help

[digit1191]

I have an old HCL laptop. 4 yrs old.. the thing is the charger got burnt in the tip (where we connect it to the laptop, that pin) and it melted the plastic coating and the pin inside.. I got a new charger from HCL today.. after 5 mins running time again some burning smell started coming..

There is no voltage fluctuation in the house.. so im guessing something wrong with the charging point of the laptop? i know it cant be changed as it comes with the motherboard please give me any ideas about what might have gone wrong. please!!!
