Laptop display randomly turns black

My dell laptop display randomly turns black. Sometimes it goes for some time with no problem than it starts turning black every minute or so until it starts “blinking” and at last it’s black most of the time.
While it’s black I can still type and it will react to my input in the background.
The OS is windows 10. I reinstalled display drivers (downloaded newest drivers) and ran some hardware tests on startup.
Any ideas how to fix this.

Thank you!

 

Laptop screen is turning black randomly

On July from last year, I bought a new Lenovo laptop. About 4 months later, my laptop screen turned black for the first time while the laptop was still running. It stopped responding and I did not find another way to turn it back on except to force shutdown
the laptop. Now, the screen of my computer is turning off more often than before and the only way to turn it back on is to force shutdown. Is there a way to stop this or is it a hardware malfunction? It almost never happens when I am home, but at school, if
I use my laptop for half an hour, the screen will turn off randomly. Please help me fix this issue because its getting quite annoying, especially when I'm working in school.

 

Surface Laptop 3 Screen Randomly turns black

The screen randomly turns black, though the back lit keyboard remains on. To fix this issue i must force shut down the laptop, though the moment it turns off it makes a pop sound. This happens every few hours and i have noticed no trend/trigger to this issue.
Really inconvenient as it closes all apps, especially frustrating when using word and all progress is lost.

Any solutions or similar problems please let me know ASAP.

Thanks
