Black screen MacBook Pro 2019 (touchbar)

Hi.

After closing the lid on my Mac and reopening it a moment after, I had a black screen.

I could hear it was awake but no lights were on the keyboard or anywhere else.

After a day I disconnected the power to see if the Mac would start up

after the battery had used its power – and yes it did and the Mac seems

normal again.

Can I do anything else if it happens another time? Sure I will have to let someone professional to take a look I guess.

Thanks for any insight.
