So let us start the troubleshooting process of Laptop display is not working or Laptop screen and external monitor not working.
First, we have to check whether the display is bad or anything else, which is causing the problem. To do so you will need to shut down/restart the laptop.
1. How to shut down/restart when the Laptop display is not working.
It’s not as difficult as you may expect to shut down when you cannot see what’s going on the screen?
Very simple, long-press the power button until the laptop is shut down. If you were working when the problem occurred, then I don’t think you can save you files because when you can’t see how are you going to save the data?
So, unfortunately, the unsaved data you are currently working with will be lost.
If you wish you can make a one minute silence for the unsaved data lose.
But this has nothing to do with your Laptop screen and external monitor not working problem.
2. Check if the operating system is causing the problem.
Some times your laptop may start normally and also display the login page. And once you login the screen goes black.
If this is happening then your laptop is having issues related to the operating system. This may not be related to any hardware of your laptop.
3. Is your laptop is overheating?
The laptop may be overheating, and it may shut down automatically.
It may only turn off the display by cutting power to the GPU.
You can shut down the laptop for a few hours and then try starting it again.
And after a few hours, if the device starts normally, this means its an overheating issue.
Before we proceed any further with the troubleshooting process first make sure that there are no cracks on the screen.

Laptops must be handled carefully as they are delicate and can easily be damaged.
It could be because you have dropped your laptop, held it in a difficult angle or placed a heavyweight.
