My laptop acer aspire lite AL 15-41. I kept it on sleep after studying and when I woke up the next day after oning it its processor is making sound but the screen is black .does anyone have an idea on what the problem could be ? I browsed through so many posts but known of them helped me solve this problem . I also gave to a repairman he said the voltage is not being passed evenly throughout the laptop
