So basically what happened was that I dropped my macbook pro the beginning of this year and it severely cracked the bottom right screen and the bottom screws holding the screen broke so the underneath of the macbook is exposed. And just recently it won't startup anymore as it now will turn on and go to the loadup screen with the apple logo then shutoff.
So can anyone tell me a estimate of the total repairs it will cost me to repair my laptop? The warranty on the macbook pro won't cover the repairs because of how it was damaged and I have no proof of purchase for it.
Any help would be much appreciated, I am very worried on what to do.
