Question My laptop screen is black and unresponsive, but the laptop boots ?

How to get screen working again.
My screen is now totally black and I get no response on the screen. But the laptop boots.
I followed a guide (https://www.tonymacx86.com/threads/...-card-by-unlocking-the-insydeh20-bios.235692/) on a site on how to force the laptop to use the dedicated Nvidia gpu.
After I did what it told me to do, the screen just turned black and I get no response on it. But the laptop boots, and I even heard a windows notification sound. Any idea on how to fix the issue? Thanks!!!

try a external monitor and undo what the guide told you to do

I have tried with an external monitor.
The problem is my screen never turns on, and it does not give a hdmi output. So I can't undo the changes

the guide is for disable discrete gpu not igpu
and since you did it in bios. need to reset bios.
look up online for your exact laptop model to see if there is an option to reset bios
