I was on my laptop, which was working fine. I took a picture with the photobooth application than out of nowhere the screen turned off. I figured it was dead so I plugged it into charge. I waited about an hour, and opened it. the screen popped up, and could be seen clearly, but then flashed off almost immediately. I tried to turn it off but it wouldn't. it is still on, but every time I open it the screen flashes, then just goes black again. what should I do? does anyone have an idea of what could have happened? thanks, so much!
