When turning on my notebook, the screen is suddenly black, it has no lighting on a close look, but you can see what is the reason for that?

Windows 10? There are different settings for the brightness between battery and mains operation. So change the operating mode and see if that changes. Then, when you can see something, change your attitude to the way you see nothing.

Example: I had a notebook, since the brightness for network operation was set to 0 after an update. This is absolutely pointless, but Windows, well, Microsoft does not have it. So battery power started and changed in the power settings.

There's probably the backlight failed. You may need a new inverter for lighting…

So if you see something then I would first connect a screen and check the settings… If everything is normal, lighting is broken the lighting or the connection is severed…
