I left my laptop on last night when I went to bed. I got up this morning and it was dead. The power lights were on but the PC was dead. I have had this laptop maybe a month at the most. I make an appointment to take it into Best Buy. The guy pushes the power button and it comes on. He said it's a glitch that showed up in Windows 8 and it still shows up in Windows 10. When it shuts down on it's own for updates it gets stuck in off. You have to push the power button for at least 10 seconds to unfreeze it so it will come back on. I really hate PC's. At least I know now. The guy was really nice though, not condescending or anything. He probably had a good laugh after I left though.
