Laptop died

Long story short, it was working perfectly fine and then I put it in my case (Which had a iPad with a magnetic case in it) and it stopped working after I brought it to my mothers house. I suspected that the magnetic iPad case caused a screw to come lose or something so I opened my computer and surely enough, that was the issue. After I fixed it however, nothing changed. When I opened the laptop nothing seemed to be broken, if I could receive some help it would be appreciated.
