for your spec its only HP DV6-4001. You can get a Notebook cooler and it will solve your heating issue. The heating is due to dedicated VGA as well. Other than this their is no other issue. If the DV models r not good HP will not be selling so many in SL.
Softlogic is the Agent for Dell. Buy from them. If you buy from any other place you'll have a lot of trouble for warranty claims/after sales service for it.
