I suppose most laptops would have adaptors that would work with dual voltage 110V or 230V. But just make sure that it is so, otherwise it might fry the internal laptop components!!! In case it supports 230V, you only need a cheap pin-adaptor which will map the flat US-pins to rounded Indian-pins.
In an unlikely case that it does not support 230V, you will need a transformer (sold in electrical shop) to step-up voltage from 110V to 230V.
