The black line shows where the slight bump is. It is not visible in the picture due to my camera phone quality and the flash. It is not really visible in real life either, but noticeable enough for me to find it without dificulty. If I run my finger over the area I can feel a bump. Maybe about 1mm overall in height. Will there be any problems in the future? Does anyone else have this problem with their laptop and what would you do? EDIT: I took 2 better pictures, the line is now visible at a different angle after I ran my fingernail through it a couple of times.
