Dropped my MacBook: Startup with the chime but black screen

Hi guys,

I recently dropped my MacBook swinging away from my arm to the floor, the MacBook dropped is covered with a zipped MacBook sleeve, I would say its a strong impact as the sleeve is punctured with a tiny hole and eventually dented a little on my MacBook.

The first thing I do after the drop is take it out and try to startup my MacBook.

My attempt to startup the MacBook is a failure, as I heard the usual chime when you startup a MacBook, but the screen stays black, the screen has LIGHT, that means the monitor is still functional.

Then, I tried to type my MacBook password with the black screen, after a few seconds, the keyboard lights up. I guess this means that I was able to login, but after the login, I tried to interact with the keyboard light buttons, sound buttons, PLAY button, but unfortunately, nothing happened.

I've tried to search in Google for answers, but most of the post I see are people who could not start up their MacBook.

I hope someone could help me out on this problem as I have zero computer knowledge.

Sorry for my bad English as English is not my native language.

Thank you!
