I was watching videos on my laptop and i hit my laptop and then the screen glitched out so i turned it off and went somewhere else. Then as i came back to my laptop i tryed to turn it on but the power button is the only thing that lights up. I tryed the f8 and shift method but the laptop just starts up as per usual then shuts down leaving the power button lit , the screens stay black of course. I try most of the methods on the internet but nothing happens. Please help
