I don't know about HP or SONY but Dell is absolute crap when it comes to their after sales service in India. My dell laptop had a fault....it help shutting down on its own. When I talked to the dell authorities they said that they will call me later. But they didn't till this day. I had to get my laptop repaired from a local store.
Buy whatever you want but just stay way from DELL.

From what I know Sony has the best service. They repair laptops quick and their customer support is pretty good. But you shouldn't just decide what to buy on terms of warranty , and on tech specs , Sony is behind every one these days.
