Windows 10: Why does my laptop show black screen upon startup and why did my laptop get unlocked by an...

During startup of my Windows 11 PC, I encounter an error related to graphics and display sometimes. The screen becomes completely black and I cannot even see my mouse pointer. To overcome this issue, during entering my PIN, I purposely enter an incorrect PIN and then I enter the correct one. This solves the problem. However, today I entered the wrong PIN and still the computer got unlocked and I had access as if I had entered the correct PIN. Now, I need help with two things: 1-How can I solve this display problem that is occurring very often? and 2-Can Microsoft or any representative explain

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

Laptop Goes to Black Screen at Startup

Hi Greg,

Unfortunately my laptop did not make it past step two. I've gone into my BIOS menu and had my installation media drive as the prioritized boot option with fast boot disabled, but I am still getting to a black screen after my manufacturer logo appears and
the circle spins. Attempting to reach the Advanced Startup Options menu by force shutting down the laptop three times in a row also led to a black screen. Are there any other options?
