To be true Guys I am writing this review through my Dell vostro laptop. It completely hangs. manytimes it get stuck and it is difficult to use it, Also it has many battery issues. The RAM of laptop is also less due to which many of the software does not work properly. But the laptop is having Great Speed. But then also I recommend not to buy dell vostro 1540 laptop .you can buy other Dell laptops. Sony is also creating reliable laptops. You can buy it.
