I have tried all the methods online, SMC reset, PRAM reset, type in password and hit return, and key press sequence to restart the computer (even turning on the brightness, yes!). I’ve also tried to connect it to a monitor and that doesn’t work either. One thing is to be noted, it would first turn on completely black, but then after a minute or so the light would be on, but it remains black (I hope that makes sense). And if I boot it up with it connected to the monitor, the monitor would first be white, then it would turn grey when the screen (of the macbook itself) lights up. Anyone has any clue as to what to do?
