Update = After completing troubleshooting, a DELL-Cares agent setup a part replacement.
I have worst experience with my Inspiron 15 3511 and also with the tech support. I purchased the laptop on Nov 11th , one of the hinges was broken, preventing me opening the laptop because it was damaging the LCD pushing it out of its bezel. I shared my experience with Dell customer executive service, they were  open a new service request for me after i sent them some pictures showing the damage. it's been 19 days no one is responding. till now i didn't get any update.I do not understand when simple opening and closing of the lid (normal use of the laptop) can break these hinges Dell installed in the laptop in less than a 6 months! if the situation is like this i will complaining this issue to concern authorities.i will give bad feedback on dell service. And do not recommend any one to bye a dell product. So please resolve the issue as early as possible..
