My laptop screen/monitor Cannot turn on! But the machine/motherboard is on!

Mar 18, 2023
I always take care my laptop very softly, so the external factor or damages cause is impossible. Yesterday before it happened, i download application from the forum or website, so i bet is because a virus or system crash. What should i do? I cant do anything, Even i want to restore or reset the pc is black, so its impossible to do that. Im already restart the EC with pushing the tiny hole behind the laptop motherboard but its still same. Nothing happened, my laptop still black but the machine is on! What happen with my laptop? What should i do to turn on my screen?
