If this is a business system (i.e., time-critical support), start with the Precision 3000 series. Do not expect the same level of support from an Inspiron or Vostro system -- those are consumer-grade models with limited, consumer-level support.  
Dear members, I have been using a single Dell laptop for past 9 years with no upgradation and it has been working great for me. But now I want to buy a new Dell laptop which I can use for both gaming and for normal purposes like using photoshop and video editing. Please recommend me a good laptop which is under Rs 1,00,000. Thank you.
