So, I was trying to take my laptop (hp elitebook 830 G3) casing off for unrelated reasons, when I accidentally made the little part circled in the image spark. I wanted to know what this piece was so I knew if I could replace it and how. I've searched the user manual but I can't really figure it out. I also asked my sister and she said I'm gonna have to buy a whole new motherboard but I still have hope.
