I do have a Dell Inspiron N5010 laptop. I bought it around six years back for 40000 rupees. Its the best laptop in that range. The service of dell is excellent when compared to others. They come at your doorstep for servicing. They charge very less for servicing.
Coming to the laptop working condition, its simply the best. The sound of dell is best in its quality. This laptop can be used for playing games for hours without any problem of over heating until u have a graphic card of 1gb in the selected model. The battery back up is awesome. People say Dell laptops / processor will get damaged very soon. But trust me am using it from six years and I have just seviced it twice and changed the battery once. Not more than that. If u think of buying any dell laptop within some range. I suggest u this.
