MacBook stuck on black screen
About a month ago my 2019 MacBook Pro was stuck on a blank screen.
It’s like the laptop was still working, but the screen stopped working. There would be a sound when I plugged the charger in, I could hear the fans working, I could even charge my phone. But the screen stayed black.
Eventually I found a fix online. I reset something by holding keys down after pressing the power button and it started working again.
Anyways, this exact same thing has happened (black screen), but I’ve forgotten what I reset to make it work again.
Can anyone suggest what I could try?
It wasn’t the SMC or PRAM/NVRAM. It was another one which I found only after hours of searching.
Any help would be greatly appreciated.
