My laptop won't turn on. Maybe it's on but my monitor is all black. And when I force it to shut down by click'n'hold my power button. But then when I power it on back 2 seconds later it goes to sleep mode. No boot animation or anything. But nothing. It goes to sleep mode. I'm not that certain if it's sleep mode but it flickers on'n'off. What should I do? And before that, my USB port won't work. I fixed it by updating them but they are updated!! What the efffff!!? What should I do?? Need help pleeeeeaaase!
