Dell Latitude 3350 was not so good as I thought, when I buy it after 1 month it gets hang and battery discharge and speaker problem arises.
I recommend you to buy HP laptops for a heavy use. If you use a designing softwares like Autocad software catia software then you to buy a minimum of 2GB graphics card which should install in your computer.
Please don't go through Dell Latitude 3350 it is not that much of relabel computer for the heavy use. Or go through Lenovo which is cheapest laptops, and with the best features. Thank you
