Heating above laptop hard disk

If it's under warranty, demand that it's either fixed or replaced. There is no reason for a new laptop to have problems. Sure, some stuff might slip past quality control, but if the part was replaced and it's acting the same way, I'd want a new replacement laptop.

i'am asking for that ma friend. but the service claims that they can replace the laptop only if complaint occurs within the first 7 days.  

in my case they are saying that only the damaged part will b replaced. dont knw wat to do now. already changed the hard disk within 20 days. now its the 6th day after i got it back serviced. the same heating symptom happening again.
