Black Screen Turning Laptop on, on Battery

[TheLamerLinux]

Hello,
I've came back to Linux Lite because I was missing how great it was on my computers. I'm having an issue with my new laptop that I use for college and personal uses. When I plug in the charger in my laptop it boots up just fine but when I unplug the laptop and turn it on I get a black screen. I've done an update and still no fixed.

I've tried other distros and never had this problem unless I had my monitor plugged in and installed it, but I had nothing plugged in except the USB drive.Here is the laptop specs:

Hi!

Second post I see here with same issue and also a Ryzen config.

A quick gogole search indeed shows you are not alone, there is a similar bug reported in Ubuntu forums :
https://bugs.launchpad.net/ubuntu/+sourc...ug/1870971

Other posts mentions to try and remove the battery, is removable, which is not really useful.
But, a post mentions to try and change display output with an external monitor plugged in.
This could be useful, I would also try to just trying the "Function Key + Change Monitor output key" without any other monitor plugged in, maybe this could "do" something.
