Black screen on brand new M1 Pro
Woke up this morning, opened my laptop that I was using last night, and the screen was black. Rebooted, nothing. Reset NVRAM, SMC, tried recovery mode. Nothing, screen is just totally black.
Nothing shows up with a flashlight, and the Apple logo on the lid does not light up (this is a 2021 MBP—the logos are supposed to light up, unlike the previous models).
If I boot the computer, wait ~30 seconds, and type my password, it will log in and I can plug in an external display which works fine. In sys prefs and sys profiler, I can see the internal retina display, which shows up fine and does not report any errors.
So the display is connected—the computer sees it—but is getting neither video nor backlight. I am at a total loss. I got this laptop delivered less than 3 weeks ago, brand new. It was just sitting on my desk all night. Any ideas?
