Identification and Background

Released in late 2012 as a part of Dell's Inspiron product line that targets budget and design, the 15-3521 features 3rd Generation Intel® Core™ processors in a sleek design that’s 21 percent thinner than the 2011 model. It is just over an inch thick with a 15.6" HD display, with a textured lid for feasible grip. Other features of this laptop include a 10-key number pad, 8-in-1 media card reader, four USB 3.0 ports, HDMI port, and more. All these features make the Dell Inspiron 15-3125 a perfect competitor to Acer Aspire, HP Pavilion, and Toshiba Satellite.
