Most of the laptops from dell is nice for worlimg but not this one. My sister bought this few months ago and along with her I use this too. It has a 15.6 inch screen and 2.53 GHz processor. Hard disk is 500 GB and ram is 4 GB. Operating system is windows 7. However main problem started after some months. It was abkut battery. Battery backup is too low. It hardly runs laptop for 3hours. Another issue is heating. Somethin its get too much heated and shut downs automatically. There is no graphics card. So you cant play high resolution games on it. These are the main problem of this laptop. Otherwise this laptop is okay.
