Ok can you take good pictures of the laptop with angle on botton, keyboard, front, side and back? Upload it, I cannot find a service menu for the exact model. The picture will help to identify where the HDD is. I thought that EasyNote Butterfly is the model and S-FN-055 is the version. Usually same model share same chassis and parts are interchangeable.
Please mail me at: email@example.com and I will forward you some pictures.
