I had one of these back a couple years ago. It's a piece of shit dell shat out. My freshman year of college they had an amazing deal on these. Two of my other room mates and I got one each by random chance. Within a year all three had broken multiple times with multiple different errors. Since we all had the warranty dell replaced every part of mine and my friends basically three times each. We all ended up getting brand new laptops (alienwares) for free courtesy of dell because they realized how horrible these were. The main problem is the heat flow for these things are horrendous because the majority of the air flows out of the bottom. They ended up making a new battery that lifted it up at a slight angle but that only slightly fixed the problem.
