Question Lenovo l14 Music on startup

[deathrament]

Laptop will sometimes have a black display and upon startup will play music. I looked into the sound and it says its likey a bad screen. Problem is it has happened twice and and I've left it powered of overnite and both times now the next day the display was working g again.
I've never seen a bad screen do this, from my experience they die and never work again. Looking for help as I'm not sure if I should order a new screen or not.

You should go onto Lenovo's support site and see if you have a BIOS update pending;

either using the Detect Product feature or key in the Serial Number of your laptop into it.

If you're using Windows, open up Device Manager and see if anything is flagged with a yellow exclamation mark.
