MacBook Pro black screen but camera light on

To perform an SMC reset you need to follow the instructions for a T2 Mac:

You either hold the power button for 10 seconds after which the laptop will power off (usually with a swish of the fans) or by pressing & holding the Left Control + Left Option + Right Shift keys for seven seconds then while still holding those keys press & hold the power button for about seven seconds (you should see the laptop power off and hear a swoosh of the fans as it happens).

If you have access to another Mac you may want to try "Reviving" and "Restoring" the T2 firmware:

Beware that "Restoring" the T2 firmware will destroy all data on the laptop so I hope you have a good backup.

In my case, it ended up being a hardware (logic board) issue and required a full repair.

Then your laptop is still under warranty so it should be a free repair. Contact Apple or an Apple Authorized Service Provider to perform the repair.

Yep, I hadn't even reached the two-month mark yet when it happened to my machine. Sorry to be the bearer of bad news, although your situation may be different. If you do go the repair route, I also hope you have better luck with it than I did. I dropped it off a month ago and still don't have either the repaired machine or a replacement (which is supposedly on the way, since the repair has taken so long) in my hands yet.

Did you get this sorted out? I have the same issue (battery ran dry, green light on, not responding to anything I do) and any advice would be appreciated!

Anyone get this sorted out? Having the same issue. SMC isn’t doing it.

Great. This computer is two months old.

Thank you. I figured. It just doesn’t inspire confidence. And I live a couple hours from a shop and have a bunch of grades due next week. C’est la vie in 2020!
