Hey everyone, im new on this website and i have a question about the inside of my laptop, i have a HP Pavilion DV7 3130ED and i noticed when opening its case for cleaning it from dust that there is a open space inside of it next to the motherboard with a loose connector just hanging around in there, so my question is, what is that open space for? An graphics card or something? Or an HDD? I can provide a picture if anyone wants that.
