Dropped my laptop and now there is no display.

I accidently dropped my laptop yesterday, and when I picked it up, it was just a black screen but was still lit up. I connected it to an external monitor and it was functional. I moved my screen up and down a bit and at a certain angle, it started working again but with lots of flickering, but after a minute or so it stopped and worked completely fine for the rest of the night.

Today when I woke up, it didnt work and was not even lighting up. I opened up my laptop and reseated the ram but it didnt work. I was looking for the cmos battery but I couldnt find it and there were no videos on youtube showing how to find it.

I check the camera using the camera app and it worked.

My laptop model is: 15-dw0xxx
