This problem started a few months ago. My ASUS laptop used to work but then it would randomly shut off. I would try to turn it on but it would not work. After a few minutes to an hour, it would turn back on. It now currently is not turning on at all. It shows a flashing orange battery symbol and sometimes a solid green battery symbol. Any suggestions? I have tried unplugging everything and then holding down power button for 30 seconds.
