Just to add to this article, I have this exact problem on a 2019 13" Macbook Pro, but not after replacing a battery. Problem starting happening itself along with some intermittent mic problems. Sometimes the mic works, sometimes it does not and no one can hear me.
For me, and the same as the original poster:
> The computer wakes up, but does not light its internal screen after the lid has been shut once. The computer does "wake up" and this can be proved by connecting an external monitor. Notably, if you look in Preferences --> Display, the computer does not seem to even know it has an internal screen after re-opening, just the external one appears. No unplugging, or manual sleeping or autoboot disabling solve the problem. The only way to come back from this condition is to turn off the computer.
I've also tried resetting all PRAM, NVRAM, SMC etc. and no fix.
