Well I am very happy to have this piece of dell company here. I purchased this laptop in 2011 and it is in good condition since then. I work for more than 10 hours on it still it is not heating a lot.easy working with.fingers aren’t tired on the keys. Dell inspiron N5110 has best quality with battery reliablity for hours and it has stored a lot of load yet I dont find difficulties like we face in other laptops. If any kind of problems I face, I can call to dell directly and they come to home to redius the problems. Whtelse we can ask for.
