Windows 10: My laptop screen can't turn on, it stays black all the time

So.. it's been a while since my laptop got this problem. My Lenovo laptop turns off, became a blue screen of death or pure black screen on some time when i used it. It's either when i play a song nor searching for something on the internet.That started before the new year, approximately early December. And it became worse today, my laptop won't turn on at all—I can hear the fan and hardware inside it running but the screen just.. won't pop up. I've spammed windows+ctrl+shift+b key all the time but it won't solve anything. I tried to charge it and turning it on but it doesn't help either. Lastl

Toshiba Laptop Black Screen

I have a Toshiba Laptop, Was reinstalling windows 7 on it last night left it doing the updates then shut it down. Turned it on this this afternoon only to find the laptop screen is Black and also there is a burning smell coming from the Fan.

I connected the Laptop to a external monitor that is fine, Can go into bios, Windows boots up fine Etc.
Just took apart the laptop earlier to check all the cables where in correctly, Checked the motherboard over for any damage, burnt bits but but found nothing. Just put it back together now but im still getting this burning smell and i still cant use the laptop screen only a external screen.

I Tried Pressing FN+F5 to switch to the laptop screen, But still black screen. Any Suggestions please ?

Thanks

 

Every morning, Laptop running, screen stays black...

I ran a sleepstudy report. It's interesting, although doesn't tell me anything. I'm attaching in a zip if you want to take a look.

You can scroll down to 2020-06-23 22:55:06, as seen like below:





That is showing when I put it to sleep

Then when it auto booted for a Windows update, and how long it was on, like seen here: (just showing snippits)






Then, there is when I hard reset it:





I haven't tried the non MS drivers suggestion yet. But I did turn hibernation back on.

There's a lot of reports available via that powercfg command. I may look at some more of them.

I ran a power energy report, attached. I'm not thinking it is of any consequence, as it is a snapshot of right now, not when the problem happens. Several warnings in it too. Quick view:





I also attached another interesting report: system sleep diagnostics, attached. The sleep diag report mentions requests by Conexant ISST Audio, even though I am not playing anything through audio. They are highlighted in orange, so makes me think that is warnings. I did a requests report, and that one indicated that the Conexant ISST Audio had an audio stream currently in use.
