I also have a dell inspiron 15r SE 7520 I think it's having mb issues cause it randomly crashes but it works I use it for movies. Itvhas a 3rd gen Core I7 processor 120gb HDD (100GB I have dedicated to virtual machine running Windows 10) and a 33gb SSD with Ubuntu 15.1 on it. Battery still holds a great charge only has 4gb ram right now cause I lost 1 stick when diagnosing the issue I'm still looking for it its supposed to be 8gbMaybe. Sony 7.1 new?
