you cracked your LCD

check your device manager. make sure the device is connected. try updating the drivers.

dont bother. you have to take the whole thing apart. take off the back plate -> remove the battery -> take out the mother board -> youll see a metal plate held in with plastic dots (those are plastic rivets) you neet to cut them with an exacto knife and then you can get to the keyboard........ then you need to superglue the metal play back down and reassemble the entire laptop......... waste of time and effort. the entie laptop costs around 300 ..... time and labor into it will be about 400 ---- just buy a new PC
