Well, I trust you will think of this as "help". Certainly the drop has damaged something. Take it to a laptop service shop & have it diagnosed before you can know what steps or decision to take next; make sure the shop specializes in laptops. Do not try poking @ it yourself. I will warn you, laptop work, labour & the parts can be costly. Depending what the shop discovers, may be most effective/efficient to grab data from it & buy a new laptop.
There is probably nothing software related that anyone can suggest doing. It has suffered physical damage.
