Dell Inspiron 15 3542, I have been using this laptop from past one year. It has 1.7 GHz Intel Core i3-4005U 4th Generation Processor, 4GB DDR3L 1600 Mhz RAM, 500GB Hard drive, 15 inch HD LED backlit display, Intel HD graphics 4400 and 4 hours average battery. Earlier this laptop was superfast and there was no issue with it but with the passage of time it got slower. Today it takes almost 20-30 seconds to turn on and it takes so much time to do simple tasks, the programs keeps crashing even google chrome gets crashed and I have to open it again and again. I strictly do not recommend this laptop to anyone but do not buy it.
